Expert Contributor Terms

1. PARTIES, SCOPE AND ACCEPTANCE

1.1These Expert Terms of Use govern the relationship between Jerome Goerke, trading as greentech.training, Kolonnenstraße 8, 10827 Berlin, Germany, and the Expert contributing knowledge, materials or professional services. References to greentech.training identify the service provider acting under that trading name. The Expert is the person or organisation identified in the Expert Account.

1.2These Terms apply to the Expert’s use of the Website, LMS and Expert Account, development and provision of Courses, supply of Expert Materials and participation in Expert Digital Twins. The scope of each contribution, authorised use and remuneration depends on the Expert Engagement accepted by the parties.

1.3These Terms are intended for individuals and organisations acting for their professional, commercial or organisational purposes. An Expert’s separate participation as a Learner is governed by the applicable learner terms. Use of Company-facing Services is governed by the applicable Company Terms of Use.

1.4An individual accepting these Terms on behalf of an organisation represents that they have authority to bind that organisation. Acceptance does not automatically bind its employees, parent company, subsidiaries or other organisations, or authorise the use of another individual’s identity, voice, likeness or materials.

1.5By completing registration and accepting these Terms, the Expert submits an offer to establish an Expert Account under these Terms. greentech.training accepts that offer when it confirms acceptance electronically or activates the Expert Account, whichever occurs first. An automated acknowledgement of receipt does not constitute acceptance unless it expressly confirms that the registration has been accepted or the account activated.

1.6Registration does not itself commission a Course, authorise an Expert Digital Twin or create an entitlement to remuneration. An Expert Engagement is concluded when the parties accept its scope and Commercial Terms through the applicable online process or another recorded exchange. Submission of a proposal or materials for evaluation does not, by itself, establish an Expert Engagement.

1.7The deliverables, responsibilities, authorised uses, remuneration rate, calculation basis, permitted deductions, duration and other conditions presented and accepted for an Expert Engagement form part of that agreement. Course contributions and Expert Digital Twin participation may be agreed separately. A general description of available functions or potential earnings does not establish an entitlement beyond the accepted Expert Engagement.

1.8These Terms and any provisions expressly incorporated by reference must be made accessible before acceptance. The Expert must be able to retrieve and save the applicable Terms and Commercial Terms when the agreement is concluded. Publication of a later version or a different remuneration rate on the Website does not, by itself, replace the terms accepted for an existing Expert Engagement.

1.9Subject to mandatory law, any legally effective individual agreement takes precedence over these Terms. Conditions accepted for a particular Expert Engagement prevail over general provisions only to the extent of a direct conflict concerning that Expert Engagement. A general Website description does not otherwise displace obligations imposed by these Terms.

1.10The Expert’s own supplier conditions, invoice terms or other standard terms do not form part of the agreement merely because they appear in a proposal, invoice, payment document or communication. Their application requires express agreement by greentech.training. Receipt of materials or payment of remuneration does not, by itself, constitute acceptance of those conditions.

1.11Where a Company nominates an Expert, the nomination does not itself establish an Expert Engagement. The contracting party, authority to contribute the relevant materials and recipient of remuneration must be identified when the Expert Engagement is accepted. Company nomination does not automatically authorise the creation of an Expert Digital Twin.

1.12Acceptance, engagement confirmations, statements, invoices and contractual notices may be communicated electronically through the Website, the Expert Account or the relevant contact email address, except where mandatory law requires another form. No provision of this Section overrides a specific notice requirement elsewhere in these Terms.

3. EXPERT REGISTRATION AND ACCOUNT MANAGEMENT

3.1The Expert must provide accurate and current registration information, including the contracting party’s name, contact details, professional background and, where applicable, organisation details. Payment and tax information required to administer remuneration must be supplied before the first payment becomes due.

3.2Professional qualifications, experience, affiliations and areas of expertise stated in the Expert Account or submitted for publication must be accurate and capable of substantiation. The Expert must promptly correct information that becomes materially inaccurate or misleading.

3.3greentech.training may request information reasonably necessary to verify identity, authority to act, relevant qualifications or entitlement to receive payment. Any verification undertaken is limited to the information and purpose concerned. Account activation does not constitute certification or endorsement of all statements or materials supplied by the Expert.

3.4The Expert must keep account credentials confidential and restrict access to authorised persons. Where the Expert is an organisation, access must be limited to personnel acting within their assigned responsibilities. Access must be withdrawn promptly when that authority ends.

3.5The Expert must notify greentech.training without undue delay of suspected unauthorised access, compromised credentials or material inaccuracies in account or payment information. greentech.training may apply proportionate verification measures before implementing changes to payment details.

3.6The Expert Account may be used only for activities authorised under these Terms and the relevant Expert Engagement. The Expert must not impersonate another person, circumvent access restrictions or use account access to obtain unrelated Company or Learner information.

3.7The Expert determines the manner and organisation of its work, subject to the agreed deliverables, deadlines, technical requirements and coordination reasonably necessary for the Expert Engagement. Unless expressly agreed otherwise, the Expert may undertake work for other clients, subject to its confidentiality and intellectual-property obligations.

3.8The Expert is responsible for the registrations, permissions and tax obligations applicable to its activities and remuneration. Any withholding, reporting or other statutory obligation imposed directly on greentech.training remains unaffected.

3.9The Expert has no authority to enter into contracts, incur expenditure, make guarantees or otherwise bind greentech.training unless expressly authorised. Statements made in an Expert profile or Course must not imply such authority.

3.10greentech.training may temporarily restrict access where reasonably necessary to investigate suspected account misuse, verify authority or address a security risk. The Expert will be informed of the reason and any steps required to restore access unless disclosure is prohibited by law or would compromise the investigation. Any restriction must be proportionate to the circumstances.

4. SCOPE AND MANAGEMENT OF EXPERT ENGAGEMENTS

4.1Each Expert Engagement must identify the Course, Expert Materials or Expert Digital Twin concerned, the contributions required from each party and the applicable Commercial Terms. Obligations apply only to the activities included in the accepted scope.

4.2Where relevant, the Expert Engagement must specify:

4.2(a)the subject matter, intended audience and learning objectives;

4.2(b)the materials, recordings, assessments or other deliverables required;

4.2(c)the delivery format, language, technical requirements and submission dates;

4.2(d)the review process and criteria for completion;

4.2(e)any participation required in production, testing or launch; and

4.2(f)any continuing support, corrections or content updates included in the agreed remuneration.

4.3The Expert must deliver the agreed contributions within the specified timetable. greentech.training must provide the access, instructions and materials allocated to it under the Expert Engagement in sufficient time for the Expert to perform the agreed work.

4.4Each party must notify the other without undue delay of circumstances likely to materially affect delivery. Where performance depends on information, access or approval that has not been supplied, the parties must review the affected timetable and record any necessary adjustment.

4.5Course Administrators may coordinate submissions, communicate agreed requirements and arrange reviews on behalf of greentech.training. Instructions that materially change the scope, remuneration, authorised uses or delivery timetable require agreement under Clause 4.6.

4.6Changes to an Expert Engagement must be recorded and accepted by both parties before the additional or revised work begins. The agreed change must identify any effect on deliverables, deadlines, remuneration and rights of use. A request for additional work does not, by itself, oblige the Expert to perform it.

4.7greentech.training must review submitted deliverables against the agreed requirements within the period specified for the Expert Engagement or, where no period is specified, within a reasonable period. Requests for correction must identify the relevant deficiency. Corrections needed to meet the original requirements are distinguished from additions or changes to the agreed scope.

4.8Submission or approval of Expert Materials does not itself determine the publication date. Launch arrangements and any publication commitment must be specified in the Expert Engagement. Delayed or cancelled publication does not, by itself, remove an entitlement to an agreed fixed fee for work properly completed.

4.9Continuing availability for Learner questions, live instruction, technical support or periodic updates is required only where included in the Expert Engagement. Any agreed continuing obligation must specify its duration and reasonable limits.

4.10Where an Expert Engagement relies on the knowledge or participation of an identified individual, replacement of that individual requires prior agreement by greentech.training. Any approved additional contributor must have the permissions necessary to perform the assigned work and provide the relevant materials.

5. CONTENT STANDARDS AND UPDATES

5.1The Expert must exercise reasonable professional care in preparing Expert Materials. At submission, the materials must be materially accurate, suitable for the agreed learning objectives and consistent with the level of knowledge reasonably expected of an expert in the relevant field.

5.2The Expert must identify material assumptions, limitations and prerequisites relevant to understanding or applying the content. References to legislation, technical standards, software versions or professional guidance must identify the relevant jurisdiction, version or date where necessary to avoid misleading Learners.

5.3Instructions involving practical activities must identify reasonably foreseeable hazards, required protective measures and any need for qualified supervision or professional authorisation. Educational content must not imply that Course participation alone qualifies a Learner to undertake regulated or safety-critical work.

5.4Assessment questions, expected answers and explanations supplied by the Expert must correspond to the Course content and stated learning objectives. Any material ambiguity or dependency on particular assumptions must be identified so that the assessment can be configured appropriately.

5.5Expert Materials must be original to the Expert or used with sufficient permission for the agreed purposes. Sources and third-party contributions must be acknowledged where required. Confidential information, personal data and restricted Company materials must not be included without the necessary authority.

5.6Where AI tools assist in preparing Expert Materials, the Expert must review the resulting content before submission and check material factual claims, references and assessment answers. Use of such tools does not reduce the standards applicable to the Expert’s contribution.

5.7The Expert must notify greentech.training without undue delay upon becoming aware of a material error, safety concern or rights issue affecting Expert Materials that remain available through the LMS. The notification must identify the affected material and the nature of the concern sufficiently to support corrective action.

5.8Corrections necessary because submitted materials failed to meet the agreed requirements are handled under Clause 4.7. Revisions arising solely from subsequent developments, changes in standards or an expanded scope are governed by the updating obligations included in the Expert Engagement or separately agreed under Clause 4.6. No continuous monitoring obligation arises unless expressly agreed.

5.9greentech.training may temporarily restrict access to affected materials where there are reasonable grounds to suspect a material factual, safety or rights issue. The Expert must be informed of the concern and given a reasonable opportunity to respond or provide corrections, taking account of its urgency.

5.10Review, formatting or publication by greentech.training does not, by itself, constitute independent verification of every factual statement or transfer responsibility for the Expert’s original contribution. Where greentech.training materially changes technical content, it must obtain the Expert’s approval before attributing the changed content to that Expert.

6. OWNERSHIP AND RIGHTS OF USE

6.1Rights in Expert Materials remain with the Expert or the relevant rights holder. These Terms grant greentech.training the rights of use specified below and in the relevant Expert Engagement. Submission, payment or publication does not, by itself, transfer ownership.

6.2For the duration of the Expert Engagement, the Expert grants greentech.training a non-exclusive licence to reproduce, store, host, transmit and make the Expert Materials available through the Website and LMS for the agreed purposes. The licence permits worldwide access, subject to any territorial or audience restrictions recorded in the Expert Engagement.

6.3The licence includes technical processing reasonably necessary for delivery, including file conversion, compression, formatting, accessibility adaptations and integration with Course activities and assessments. Editorial changes must preserve the substance and meaning of the Expert’s contribution. Material changes to technical content remain subject to Clause 5.10.

6.4Translation, substantive adaptation or reuse in a different Course requires authorisation within the Expert Engagement or a subsequently agreed change. Approval of one Course does not automatically authorise use in unrelated Courses, Company training environments or standalone products.

6.5greentech.training may permit hosting, production and other service providers to process Expert Materials only as necessary to perform the authorised activities on its behalf. Learners may receive the limited rights needed to access and use the materials for the agreed learning purposes. These permissions do not authorise independent resale or unrelated exploitation of Expert Materials.

6.6greentech.training may identify the Expert as a contributor using the agreed professional name, biography and profile image. Promotional use of Course extracts must be limited to excerpts approved by the Expert or expressly authorised in the Expert Engagement. Such use must not misrepresent the contribution or imply endorsement of unrelated products or services.

6.7Attribution must follow the arrangements recorded in the Expert Engagement and respect the rights of the relevant authors and contributors. Existing copyright notices and required third-party acknowledgements must be preserved where applicable.

6.8Where Expert Materials contain third-party content, the Expert must identify any licence conditions or restrictions relevant to the proposed use before submission. greentech.training may decline or request replacement of material whose permissions do not cover the agreed use.

6.9The licence under this Section does not, by itself, authorise creation of an Expert Digital Twin, synthetic voice or avatar, or training or fine-tuning of an AI model using Expert Materials. Those activities require the specific authorisations applicable to the Expert Digital Twin and the relevant Expert Engagement.

6.10greentech.training retains its rights in the Website, LMS, software, templates and production tools that it supplies or develops independently of the Expert Materials. Incorporating Expert Materials into those resources does not transfer rights in the underlying Expert Materials to greentech.training or rights in those resources to the Expert.

6.11On expiry or termination of an Expert Engagement, new sales and uses of Expert Materials must cease unless otherwise agreed. The licence continues only to the extent necessary to fulfil access periods already granted to Learners, complete agreed closing activities and retain restricted records required by law. Remuneration obligations relating to those uses remain applicable.

6.12Remuneration for the authorised uses is governed by the Commercial Terms. Any exclusivity, extended licence or additional use must be expressly agreed. Mandatory rights concerning authorship, protection against prejudicial distortion, remuneration and information remain unaffected.

7. EXPERT DIGITAL TWINS

7.1Creation and operation of an Expert Digital Twin require an Expert Engagement expressly covering that activity. The agreed scope must identify the individual represented, the authorised Expert Materials, intended uses, permitted audiences and applicable Commercial Terms.

7.2The Expert Engagement must specify whether the system retrieves information from Expert Materials, uses those materials to train or fine-tune a model, or combines those methods. Authorisation for one method does not automatically extend to another or permit use of Expert Materials to develop unrelated models.

7.3Use of an individual’s name, image, recorded voice, synthetic voice or animated likeness must be expressly authorised for the relevant purpose. Where the contracting Expert is an organisation, authorisation must also be obtained from the individual concerned. Approval of knowledge-based responses does not itself authorise voice cloning or creation of an avatar.

7.4greentech.training is responsible for configuring and operating the Expert Digital Twin within the agreed scope. The Expert is responsible for the materials supplied and any review or testing expressly included in the Expert Engagement. Model selection, technical configuration and system-generated variations are not treated as contributions personally authored by the Expert.

7.5Before release, the Expert must have a reasonable opportunity to review the presentation of the Expert Digital Twin and test representative interactions. The scope and timing of that review must be agreed. Approval of a tested version does not constitute approval of every subsequent response generated by the system.

7.6The interface must clearly identify the Expert Digital Twin as an AI-enabled system. Its presentation must not imply that the individual Expert is personally participating in an interaction, reviewing each response or providing individual professional advice unless that involvement is expressly arranged.

7.7Access to Expert Materials must reflect the agreed audience and confidentiality restrictions. Company-specific or restricted materials must not be made available through a publicly accessible Expert Digital Twin unless their use for that audience has been authorised.

7.8Changes that materially expand the subject matter, audience, use of identity or permitted processing of Expert Materials require agreement under Clause 4.6. greentech.training may make technical adjustments within the existing scope, provided those adjustments do not materially alter the authorised representation or use.

7.9Either party must notify the other without undue delay upon identifying a material factual, safety, confidentiality or identity-related concern. greentech.training may restrict affected functions while the concern is investigated and must coordinate any necessary correction within the parties’ respective responsibilities.

7.10The Expert receives access only to usage information and reports included in the Expert Engagement and lawfully available for that purpose. Association with an Expert Digital Twin does not automatically grant access to identifiable Learner conversations or other personal records.

7.11The operating period, arrangements for updates and consequences of expiry or termination must be specified in the Expert Engagement. Any continued operation needed to fulfil previously granted access must remain within the agreed authorisation and applicable remuneration arrangements. Retention of restricted technical or legal records does not authorise continued public operation.

7.12Remuneration for Expert Digital Twin use is governed by the accepted Commercial Terms and the Token and payment provisions of these Terms. Creation or availability of an Expert Digital Twin does not guarantee a minimum level of usage or earnings unless expressly agreed.

8. PRICING AND EXPERT REMUNERATION

8.1The Expert’s remuneration is determined by the Commercial Terms accepted for the relevant Expert Engagement. Remuneration may comprise a fixed fee, a share of Course revenue, remuneration linked to Expert Digital Twin usage or an expressly agreed combination of these arrangements.

8.2The applicable rate and calculation basis must be displayed or otherwise provided before the Expert accepts the Expert Engagement. Where Commercial Terms are presented through the Website or Expert Account, the accepted version must be recorded and made available for retrieval. Subsequent changes to published rates do not automatically alter an existing Expert Engagement.

8.3Unless the Commercial Terms specify another calculation basis, a Course revenue share is calculated by applying the agreed percentage to the amount actually received for the relevant enrolment, excluding VAT or equivalent transaction taxes and amounts refunded or reversed. Amounts collected by a payment provider on behalf of greentech.training are included before deduction of that provider’s fees, subject to Clause 8.4.

8.4Payment-processing fees, currency-conversion costs, production costs, hosting costs, marketing expenditure and other expenses may reduce the calculation basis only where the relevant category and calculation method were expressly included in the accepted Commercial Terms. General operating expenses must not be deducted under an unspecified cost allowance. No amount may be deducted more than once.

8.5greentech.training determines the customer-facing price within any pricing limits agreed for the Expert Engagement. Where remuneration depends on the price actually paid, the Commercial Terms must specify any authority to apply discounts or promotions that reduce the Expert’s revenue share. A discount outside that authority requires the Expert’s agreement or must be funded from greentech.training’s share.

8.6Where a Course is sold within a bundle, subscription, group booking or other combined offering, the method for allocating revenue to that Course must be agreed before it is included. The allocation must be consistently applied and identifiable in the remuneration statement.

8.7Free enrolments, review access and promotional access do not generate a percentage-based payment where no revenue is received. Their permitted scope must be included in the Commercial Terms or separately agreed. Such access does not reduce an agreed fixed fee.

8.8Where more than one Expert contributes to a Course or Expert Digital Twin, each Expert’s remuneration and allocation basis must be recorded in the relevant Expert Engagement. greentech.training must not reduce an existing Expert’s agreed share merely because an additional contributor is appointed.

8.9Fixed fees become payable upon the milestones or other conditions specified in the Commercial Terms. They do not depend on enrolment numbers, Token usage or customer revenue unless that dependency is expressly agreed. Revenue-share payment holds do not automatically apply to fixed fees.

8.10Expert Digital Twin remuneration is calculated at the agreed rate using the Token allocation and usage rules in Section 9. No particular percentage applies solely because it appears in general promotional information or was offered for another Expert Engagement.

8.11Remuneration amounts are exclusive of VAT or equivalent tax chargeable by the Expert, unless expressly stated otherwise. Any such tax must be supported by the applicable invoicing requirements. Statutory deductions or withholding must be identified in the payment statement, with supporting documentation supplied where required.

8.12Revenue-based remuneration remains subject to the withdrawal, refund and adjustment provisions in Section 10 and the statement and payment procedures in Section 11. Accrual of a revenue share does not, by itself, mean that the amount is immediately payable.

9. TOKENS AND DIGITAL TWIN REVENUE

9.1Where access to an Expert Digital Twin is charged through Tokens, remuneration is attributed to the Expert when paid Tokens are used for that Expert Digital Twin. Purchase of an unused Token balance does not, by itself, generate remuneration for a particular Expert.

9.2The revenue attributable to Token usage is calculated from the amount actually received for the relevant Token purchase, excluding VAT or equivalent transaction taxes and subject to the adjustments permitted under Section 8. Unless another allocation method is expressly agreed, that amount is divided by the number of Tokens supplied for the purchase to determine the revenue attributable to each Token.

9.3Tokens included as a purchase-linked bonus form part of the allocation under Clause 9.2. Tokens supplied independently without payment, including authorised testing or complimentary access, carry no attributable revenue unless the Commercial Terms provide otherwise.

9.4Each chargeable interaction must be allocated to the Expert Digital Twin used. Where an account contains Tokens acquired through different purchases or promotional allocations, greentech.training must apply a consistent, recorded method for identifying the Tokens consumed and their attributable revenue. That method must be stated in the Commercial Terms.

9.5The Expert’s remuneration is calculated by applying the agreed percentage or other accepted rate to the revenue attributed to the relevant usage. Any permitted deductions must follow Section 8 and be identifiable in the remuneration statement.

9.6The number of Tokens charged for an interaction may reflect the type or extent of use under the applicable customer pricing. A change that alters the Expert’s agreed rate or revenue-allocation method requires agreement. Changes must not retrospectively reduce remuneration attributable to completed usage.

9.7Where an interaction draws on more than one Expert Digital Twin or combines contributions from several Experts, the revenue-allocation method must be agreed before that combined function is offered. The same revenue must not be represented as wholly attributable to more than one Expert.

9.8Tokens restored following a failed interaction, duplicate charge or billing error do not generate remuneration for the reversed usage. Any corresponding correction must identify the affected transaction. Restored Tokens may generate remuneration when subsequently used in a valid chargeable interaction.

9.9Unused Tokens do not generate Expert remuneration merely because they expire or an account is closed, unless the Commercial Terms expressly provide for an allocation of unused balances. Refunds and reversals affecting Token purchases or usage are governed by Section 10.

9.10greentech.training must maintain records sufficient to reconcile Token purchases, attributable values, usage, adjustments and Expert remuneration. The Expert’s statement must show the relevant usage totals, revenue allocation, applicable rate and resulting remuneration without disclosing unnecessary Learner information.

9.11Remuneration attributable to Token usage becomes eligible for payment only after the relevant payment hold has elapsed, the customer payment has cleared and the usage is not subject to an unresolved refund or payment dispute. Eligible amounts are included in the monthly statement and payment cycle under Section 11.

10. WITHDRAWALS, REFUNDS AND PAYMENT ADJUSTMENTS

10.1Customer withdrawal, cancellation and refund rights are governed by applicable law and the terms accepted for the relevant purchase. This Section determines their effect on Expert remuneration and does not restrict customer rights.

10.2Revenue-based remuneration is subject to a minimum fourteen-day payment hold. The hold runs from the day following conclusion of the relevant customer purchase contract. Where an applicable statutory withdrawal period expires later, the affected remuneration remains on hold until that period expires or the withdrawal right validly ends, subject to the minimum hold.

10.3Activation or opening of a Course does not, by itself, establish that a statutory withdrawal right has ended. greentech.training must apply the consent, acknowledgement, confirmation and performance requirements relevant to the purchase. A valid early expiry of the withdrawal right does not shorten the minimum payment hold.

10.4For Token purchases, the hold applies to the purchase from which the used Tokens originate. Usage after that hold has elapsed does not start a new fourteen-day hold for the same purchase. Remuneration nevertheless accrues only when the Tokens are used in accordance with Section 9.

10.5An amount becomes eligible for settlement once the applicable hold has elapsed, payment has cleared and no unresolved refund request or payment dispute affects that amount. It is included in the statement for the calendar month in which all those conditions are met and paid in the following month under Section 11.

10.6Where customer revenue is refunded or reversed, the corresponding revenue-based remuneration is recalculated using the original allocation and rate. A partial refund reduces only the remuneration attributable to the refunded portion. Refunds of unused Tokens must not reduce remuneration attributable to separately paid, completed usage.

10.7If the affected remuneration has already been paid, greentech.training may deduct the documented overpayment from a subsequent payment to the Expert. The statement must identify the original transaction, reason and calculation. Where no further payment is expected, repayment may be requested within thirty days after the Expert receives those details. An adjustment must not exceed the remuneration attributable to the reversed revenue, except for additional deductions expressly permitted under Section 8.

10.8Any hold arising from a refund request, suspected payment fraud or chargeback must be limited to the amount reasonably affected. greentech.training must inform the Expert of the reason, review the hold without undue delay and release the amount into the applicable payment cycle once the issue is resolved. Unaffected remuneration remains payable.

10.9A discretionary goodwill refund outside customer rights or an agreed refund policy must not reduce the Expert’s remuneration without the Expert’s agreement. Any broader promotional refund policy affecting remuneration must be included in the accepted Commercial Terms.

10.10Expiry of the payment hold does not prevent later adjustments for valid refunds, chargebacks or calculation errors. Amounts subsequently recovered must be restored to the Expert’s remuneration to the extent previously deducted.

10.11Customer refunds do not automatically reverse an agreed fixed fee for work properly completed. Any claim concerning defective performance or another breach by the Expert is governed separately by the relevant Expert Engagement and these Terms.

11. STATEMENTS, INVOICING AND PAYMENTS

11.1Revenue-based remuneration is accounted for by calendar month. Each statement includes amounts that became eligible for settlement under Section 10 by the end of the last calendar day of that month, using Berlin local time. Amounts becoming eligible later are included in the subsequent applicable statement.

11.2greentech.training must provide the monthly statement and pay the eligible amount by the fifteenth day of the following month. If that date falls on a Saturday, Sunday or public holiday in Berlin, payment is due on the next business day.

11.3The statement must identify the relevant Courses or Expert Digital Twins, eligible sales or usage, attributed revenue, applicable remuneration rates, permitted deductions, adjustments and total payable. Amounts remaining on hold must be identified separately with the reason for the hold.

11.4Where agreed, greentech.training may issue invoices on the Expert’s behalf under a self-billing arrangement. Otherwise, the Expert must provide an invoice satisfying the applicable requirements. A remuneration statement does not itself constitute a tax invoice unless it meets those requirements.

11.5Required payment and tax information must be supplied in sufficient time to process payment. Where a required invoice or material information is missing or incorrect, greentech.training must promptly identify the deficiency. Only the affected payment may be deferred and must be made within ten business days after the deficiency is resolved, or by the ordinary payment deadline if later.

11.6Payments are made in euros to the payment account designated by the Expert unless another currency or method is agreed in the Commercial Terms. Any conversion method or deduction for transfer charges must be expressly agreed and disclosed in the statement.

11.7No minimum payout threshold applies unless expressly included in the Commercial Terms. Any agreed threshold must specify how unpaid balances are carried forward. On final settlement, an accrued eligible balance must be paid regardless of that threshold.

11.8The Expert should notify greentech.training promptly of a suspected statement error, identifying the disputed entry and reason. Failure to object within a particular period does not, by itself, constitute acceptance of an incorrect statement or waive a valid claim. Undisputed amounts remain payable by the applicable deadline.

11.9greentech.training must investigate a reasonably substantiated discrepancy and provide the information necessary to explain the calculation, subject to confidentiality and data-protection requirements. Confirmed underpayments must be corrected within ten business days after confirmation. Overpayments are handled under Section 10.

11.10Fixed fees are invoiced and paid according to the milestones and deadlines specified in the Commercial Terms. Where no payment deadline is specified, payment is due within thirty days after completion of the agreed milestone and receipt of a compliant invoice.

11.11Expiry, suspension or termination of an Expert Engagement does not extinguish accrued remuneration. Eligible amounts remain subject to the ordinary payment cycle, while amounts still on hold are settled once the applicable conditions are met.

12. CONFIDENTIALITY AND PERSONAL DATA

12.1Each party must protect confidential information received in connection with an Expert Engagement. This includes unpublished Expert Materials, restricted Company Content, technical configurations, access credentials, non-public commercial information and information concerning identifiable Learners or Company personnel.

12.2Confidential information may be used only to perform the relevant Expert Engagement or exercise rights under these Terms. Disclosure is limited to personnel, service providers and professional advisers who require access for that purpose and are subject to appropriate confidentiality obligations. Publication expressly authorised under Sections 6 and 7 is permitted within the agreed scope.

12.3Confidentiality obligations do not apply to information that the receiving party can demonstrate was already lawfully known without restriction, becomes public without a breach, is independently developed or is lawfully received from another source without a duty of confidentiality.

12.4A party may disclose information where required by law or a competent authority. Where legally permitted, it must notify the other party beforehand and limit disclosure to the information required. This Section does not restrict legally protected reporting of wrongdoing.

12.5Each party must comply with the data-protection requirements applicable to its activities. greentech.training’s processing of Expert registration, contact, payment and account information is described in the applicable Privacy Policy. Acceptance of these Terms does not itself constitute consent to optional personal-data processing.

12.6The Expert may access Learner information only to the extent necessary for the assigned teaching, assessment or support responsibilities. Such information must not be used for independent marketing, recruitment or unrelated profiling, or disclosed to a nominating Company without authorisation and a lawful basis.

12.7Data-protection roles depend on the activities actually performed. Where the Expert processes personal data on behalf of greentech.training, the required processor terms must be agreed before access begins. Where either party independently determines the purposes and means of processing, that party is responsible for its lawful basis, transparency and other controller obligations. These Terms do not, by themselves, replace a required processing agreement.

12.8Personal data and confidential information must not be entered into external AI tools, personal storage accounts or other unapproved services in connection with an Expert Engagement. Any authorised use must remain within the agreed purpose and applicable provider arrangements. Where access or disclosure constitutes an international transfer, the required transfer safeguards must be in place before it occurs.

12.9Each party must apply security measures appropriate to the information under its control, including restricted access, secure transmission and storage, and prompt removal of permissions when access is no longer required. The Expert must use the approved systems and must not create local copies of Learner records unless necessary and authorised.

12.10A party becoming aware of unauthorised access, loss or disclosure affecting information received under an Expert Engagement must notify the other without undue delay and provide the information reasonably needed to investigate and contain the incident. Each party remains responsible for any statutory notifications applicable to its role.

12.11The parties must provide reasonable assistance with requests concerning personal data processed under an Expert Engagement. An Expert receiving a request concerning processing performed on greentech.training’s behalf must promptly forward it and act on the applicable instructions. An Expert acting as an independent controller remains responsible for responding to requests concerning that processing.

12.12When information is no longer required, or the Expert Engagement ends, confidential information and personal data must be returned or securely deleted as applicable, subject to continuing authorised uses, lawful retention requirements and any relevant processing agreement. Retained copies must remain restricted to their justified purpose. Confidentiality continues for as long as the information remains confidential, and personal-data obligations continue for as long as the information is retained.

13. PLATFORM OPERATION AND SUPPORT

13.1greentech.training operates the Website, LMS and Expert Account functions required for the agreed Expert Engagement. Any specific availability commitment, technical integration or enhanced support arrangement must be included in that Expert Engagement.

13.2Access may be interrupted by maintenance, updates, security measures or technical faults. greentech.training must take reasonable steps to minimise disruption and provide advance notice of planned work likely to materially affect the Expert’s activities, where reasonably practicable.

13.3The Expert is responsible for the equipment, internet connection and software needed to access the agreed functions and prepare deliverables in the specified formats. greentech.training must communicate material technical requirements before the relevant work begins and give reasonable notice of changes requiring action by the Expert.

13.4Technical faults and access problems must be reported through the support channel identified in the Expert Account or Expert Engagement. Reports should contain sufficient information to identify the affected function and reproduce the problem, without unnecessarily disclosing personal data or confidential information.

13.5greentech.training must assess reported faults and take reasonable steps to resolve issues within its control, prioritising their impact on security, access and agreed delivery. No particular response or resolution time is guaranteed unless expressly agreed.

13.6Routine support covers access to and operation of the agreed functions. Content production, extensive file conversion, additional training and bespoke technical development are included only where specified in the Expert Engagement. Additional chargeable work requires prior agreement.

13.7greentech.training may make technical changes necessary to maintain security, compatibility and functionality. A change that materially reduces an agreed function or prevents performance of an Expert Engagement must be addressed through an agreed adjustment or the applicable termination provisions. Technical changes do not, by themselves, amend the Commercial Terms or authorised uses of Expert Materials.

13.8The Expert must retain copies of original Expert Materials and production files under its control. This does not reduce greentech.training’s responsibility for records and systems that it is required to maintain under these Terms.

14. RESPONSIBILITY AND LIABILITY

14.1Each party is responsible for the obligations allocated to it under these Terms and the relevant Expert Engagement. The Expert remains responsible for the materials, permissions and professional contributions supplied by the Expert. Technical processing, review or publication by greentech.training does not, by itself, constitute a guarantee of those contributions.

14.2greentech.training does not guarantee enrolment numbers, sales, interactions, commercial opportunities or earnings unless expressly agreed. Forecasts, illustrative calculations and promotional examples do not establish a minimum revenue commitment.

14.3Nothing in this Section excludes or limits liability for intentional misconduct, gross negligence, culpable injury to life, body or health, fraudulent concealment or other liability that cannot lawfully be excluded or limited. Liability under an expressly assumed guarantee is governed by that guarantee.

14.4Subject to Clause 14.3, greentech.training is liable for ordinary negligence only where it breaches an essential contractual obligation. An essential obligation is one necessary for proper execution of the Expert Engagement and on whose fulfilment the Expert may ordinarily rely. Liability is limited to loss foreseeable and typical for that Expert Engagement when concluded. Liability for ordinary negligence concerning other obligations is excluded.

14.5For claims governed by Clause 14.4 arising from the same event or a series of connected events, the monetary limit is the total remuneration paid or payable to the Expert under the affected Expert Engagement during the twelve months preceding the first event. Where that amount is insufficient to cover the loss foreseeable and typical when the Expert Engagement was concluded, the limit is that higher foreseeable and typical amount. The calculation does not include remuneration under unrelated Expert Engagements.

14.6The Expert must reimburse greentech.training for amounts payable under justified third-party claims to the extent caused by the Expert’s intentional or negligent breach of obligations concerning rights in Expert Materials, authorisation to use an individual’s identity, confidentiality or personal data. Recoverable amounts include reasonable and necessary legal defence costs. This obligation does not cover the portion of a loss caused by greentech.training’s own breach, unauthorised modification or use outside the agreed scope.

14.7greentech.training must notify the Expert without undue delay of a claim for which reimbursement may be sought and provide a reasonable opportunity to participate in its defence. Any settlement charged to the Expert requires the Expert’s prior agreement, which must not be unreasonably withheld. Urgent protective steps may be taken where necessary to preserve rights or prevent additional loss.

14.8The limitations granted to greentech.training under Clauses 14.4 and 14.5 do not limit the Expert’s obligations under Clause 14.6. Compensation must not be recovered twice for the same loss. Each party must take reasonable steps to mitigate loss, and any contribution by the claiming party must be taken into account.

14.9The limitations applicable to greentech.training extend to claims for damages and reimbursement of wasted expenditure, regardless of their legal basis, and to claims against persons acting on its behalf within the scope of their assigned activities. They do not reduce accrued remuneration, amounts properly due under payment statements or repayment obligations concerning identified overpayments.

14.10This Section governs responsibility between greentech.training and the Expert. It does not restrict mandatory rights of Learners, data subjects or other third parties.

15. DURATION, SUSPENSION AND TERMINATION

15.1The Expert Account continues until terminated under this Section. Each Expert Engagement has its own duration and obligations. Closure of the Expert Account does not, by itself, terminate an existing Expert Engagement.

15.2Unless another period is expressly agreed, an Expert Engagement covering the continuing publication of a Course has an initial publication term of twelve months from the date the Course first becomes available to Learners. greentech.training must communicate that date to the Expert. Development deadlines and any commitment to publish remain governed by the Expert Engagement.

15.3Either party may terminate the continuing publication arrangement by giving at least thirty days’ notice, effective no earlier than the end of the initial publication term. If neither party gives notice, the arrangement continues for an indefinite period and may subsequently be terminated on thirty days’ notice.

15.4An Expert Engagement limited to specified production or development work concludes upon completion of its agreed obligations, subject to any continuing licence or other expressly agreed obligation. The operating period and ordinary termination arrangements for an Expert Digital Twin must be specified in its Expert Engagement under Clause 7.11.

15.5Temporary restrictions under Sections 3, 5 or 7 must be limited to the affected access, materials or functions where reasonably practicable. greentech.training must communicate the reason and any steps required to resolve the issue, unless disclosure is legally prohibited or would compromise protective measures. Restrictions must be reviewed and lifted when their justification ends.

15.6Either party may terminate an Expert Engagement for a material breach where the other party fails to remedy it within a reasonable period following notice identifying the breach. Immediate termination is permitted where the breach cannot be remedied or circumstances make continued performance unreasonable. Mandatory termination rights remain unaffected.

15.7Termination notices must be given in text form, including by email or through an account function that records the notice and makes it retrievable. The notice must identify the Expert Account or Expert Engagement concerned. Notice periods run from receipt by the other party.

15.8When a Course publication arrangement ends, new sales must cease. Existing Learner access and the limited continuation of rights in Expert Materials are governed by Clause 6.11. After receipt of termination notice, greentech.training must not extend existing access periods or grant longer access than previously offered without the Expert’s agreement.

15.9Existing access need not continue where doing so would be unlawful or create a material safety, confidentiality or rights risk. In that event, greentech.training must address the affected Learner arrangements under the applicable learner terms and law. Any resulting remuneration adjustments are governed by Section 10.

15.10An Expert Digital Twin must be deactivated when its agreed operating authorisation ends, except to the extent that continued operation is expressly authorised under Clause 7.11. Retention of underlying records or technical components does not permit further public interaction or new sales.

15.11Either party may close the Expert Account on thirty days’ notice, subject to arrangements necessary to complete any continuing Expert Engagement. Where access is restricted or closed, greentech.training must provide an alternative means of receiving outstanding statements and contractual notices.

15.12Final payments are governed by Section 11, and return or deletion of information by Section 12. Termination does not extinguish accrued rights or obligations intended to continue, including authorised existing Learner access, confidentiality, payment adjustments and applicable liability provisions.

16. CHANGES, GOVERNING LAW AND FINAL PROVISIONS

16.1greentech.training may publish revised Terms for future Expert registrations and Expert Engagements. Revised Terms apply only where made available before acceptance and validly agreed. Existing Expert Engagements remain governed by the version accepted when they were concluded, unless the parties expressly agree otherwise.

16.2Continued account use, silence or failure to object does not, by itself, constitute acceptance of revised Terms. Continuation of an Expert Engagement beyond its initial term under Section 15 does not automatically introduce a later version.

16.3These Terms and the Expert Engagements are governed by German law. Mandatory provisions applicable irrespective of the chosen law remain unaffected.

16.4The courts of Berlin, Germany, have exclusive jurisdiction where a jurisdiction agreement is legally permitted and the applicable requirements are satisfied. Otherwise, jurisdiction is determined by the applicable statutory rules. Mandatory exclusive jurisdiction remains unaffected.

16.5Each party must maintain current contact details for contractual communications. Electronic communications and termination notices are governed by Clauses 1.12 and 15.7 respectively. A change of contact details does not alter the identity of the contracting party.

16.6Failure or delay in exercising a contractual right does not, by itself, waive that right. A waiver concerning a particular breach does not automatically extend to another or subsequent breach.

16.7If a provision is ineffective or does not form part of the agreement, the remaining provisions continue to apply, subject to applicable law. The resulting gap is governed by the applicable statutory provisions. An ineffective provision is not automatically replaced by a broader right or obligation.

16.8The English version is the agreed contractual text unless another language version is expressly accepted as governing. Any translation supplied solely for convenience does not amend the agreed terms.
