Terms of Service

Effective: 23 May 2026 Version: 1.0 Applies to: the AIIA platform and aiia.run

These Terms of Service ("Terms") govern access to and use of the AIIA platform — a multi-model AI orchestration service that produces structured analytical artefacts for institutional decision-making. AIIA is a business-to-business service for professional users. By creating an account, using the platform, or executing an Order Form, the Customer accepts these Terms.

1. Parties and scope

These Terms form a binding agreement between

AIIA UG (haftungsbeschränkt) Kellinghusenstraße 8, 20249 Hamburg, Germany Registered with the Amtsgericht Hamburg, HRB 199065 Represented by managing director Alwin Brehde

(hereafter "AIIA", "we", "us") and the legal entity that creates an account or executes an Order Form (hereafter "Customer", "you").

These Terms apply exclusively to entrepreneurs (Unternehmer) within the meaning of § 14 BGB, legal persons under public law, and special funds under public law. The Service is not offered to consumers (Verbraucher) within the meaning of § 13 BGB. Any deviating or supplementary terms of the Customer shall not become part of the agreement, even if AIIA does not expressly object to them, unless AIIA agrees to their applicability in writing.

Where the parties enter into an individually signed Order Form, Master Services Agreement, or Data Processing Agreement, those documents take precedence over these Terms in the event of conflict, in that order.

2. Definitions

• "Service" / "Platform" means the AIIA software-as-a-service offering accessible via aiia.run, its sub-domains, and any related APIs and documentation.
• "Customer Content" means all data, documents, queries, prompts, instructions, and other inputs the Customer or its Authorised Users submit to the Service.
• "Output" means the analytical artefacts, reports, traces, structured data, and other results that the Service generates from Customer Content.
• "Authorised User" means an individual employee, contractor, or affiliate of the Customer whom the Customer has authorised to access the Service.
• "AI Provider" means a third-party model provider used by AIIA to perform inference — currently Anthropic, OpenAI, Google, and Perplexity.
• "Order Form" means a signed or electronically accepted order specifying tier, scope, term, and fees.
• "DPA" means the Data Processing Agreement entered into between the parties under Art. 28 GDPR.
• "Documentation" means the written and online materials AIIA makes available describing how to use the Service.
• "Confidential Information" has the meaning set out in Section 9.

3. Conclusion of contract

The presentation of the Service on aiia.run is not a binding offer. The Customer makes a binding offer by completing the order process, signing an Order Form, or activating a paid plan. A contract is concluded when AIIA accepts that offer — by countersigning the Order Form, sending an order confirmation by email, or first providing the Service.

All commercial terms (tier, scope, fees, billing cycle, term) are governed by the applicable Order Form. Where no Order Form is in place, free or trial usage is governed exclusively by these Terms, and AIIA may suspend or withdraw such access at any time.

4. The Service

AIIA is a software-as-a-service platform that orchestrates multiple third-party AI models in structured analytical workflows. A single analysis may involve research, expert agent reasoning, adversarial debate between agents, conflict detection, deterministic calculation, and the rendering of outputs in institutional formats.

AIIA's contractual obligation is to make the Service available for the Customer's own use in accordance with the Documentation and the Order Form. The legal nature of the relationship is that of a contract for services / lease of software (Mietvertrag within the meaning of §§ 535 ff. BGB applied analogously to SaaS, as recognised by German courts).

AIIA continuously develops the Service. Updates, new features, performance changes, and modifications to AI Provider mix are part of normal Service evolution and are not considered a defect, provided they do not materially diminish the contractually agreed functionality. Material reductions in functionality require advance notice to the Customer of at least 30 days.

5. Access and accounts

The Customer accesses the Service via accounts assigned to Authorised Users. The Customer is responsible for the actions of its Authorised Users and for maintaining the confidentiality of credentials. Credentials must not be shared between individuals. Multi-factor authentication, where offered, must be enabled for all Authorised Users.

The Customer is responsible for the technical prerequisites at its end (modern browser, sufficient internet connectivity, valid email infrastructure). AIIA's responsibility for connectivity ends at the egress of its hosting provider's network.

6. Licence and intellectual property

6.1 Licence to the Service

Subject to the Customer's compliance with these Terms and timely payment of fees, AIIA grants the Customer a limited, non-exclusive, non-transferable, non-sublicensable right to access and use the Service for the Customer's internal business purposes during the term of the agreement.

6.2 Reservation of rights

The Service, the underlying software, the AIIA orchestration logic, prompts, model routing, calculation engine, Output Lens templates, Documentation, brand, and all related intellectual property remain the exclusive property of AIIA and its licensors. No rights are granted to the Customer except those expressly stated in these Terms.

6.3 Customer Content

The Customer retains all rights in Customer Content. The Customer grants AIIA a limited, non-exclusive, worldwide licence to host, process, transmit, and display Customer Content solely to provide the Service to the Customer and to comply with applicable law.

6.4 Output

Subject to AIIA's underlying intellectual property in the Service and to the rights of the relevant AI Providers, AIIA assigns to the Customer such rights in the Output as are necessary for the Customer to use the Output for its internal business purposes. The Customer is responsible for evaluating the Output before relying on it externally.

6.5 Feedback

If the Customer provides suggestions, ideas, or feedback regarding the Service, AIIA may use that feedback without restriction or compensation, provided it is incorporated only in an anonymised and aggregated form.

6.6 Third-party components

The Service incorporates third-party components (including AI Provider services and open-source software). The Customer's use of such components is subject to the applicable third-party terms, which AIIA will make available on request.

7. Acceptable use and Customer obligations

The Customer shall not, and shall not permit any Authorised User or third party to:

• use the Service in violation of applicable law, including export controls, sanctions, anti-money-laundering rules, securities regulation, and data protection law;
• submit Customer Content that the Customer has no right to submit, that infringes third-party rights, or that contains malware, exploits, or material designed to disrupt the Service;
• use the Service to generate or disseminate unlawful content, defamatory material, content depicting child sexual abuse, instructions for the manufacture of weapons of mass destruction, or content designed to deceive identification of natural persons;
• attempt to reverse-engineer, decompile, or extract the source code, model weights, training data, prompts, or trade secrets underlying the Service, except to the extent expressly permitted by mandatory law (§ 69e UrhG);
• use the Service to build a competing product or to benchmark the Service for publication without AIIA's prior written consent;
• circumvent quotas, rate limits, security controls, or access controls;
• resell, sublicense, or make the Service available to third parties outside the Customer's group;
• use the Service to process special categories of personal data (Art. 9 GDPR) or personal data relating to criminal convictions (Art. 10 GDPR) unless the parties have expressly agreed appropriate safeguards in writing.

The Customer must promptly notify AIIA of any actual or suspected breach of these Terms, security incident, or unauthorised access.

8. Nature of AI output — what AIIA is and is not

Read this section carefully. The Service is a software tool. It is not a regulated financial, legal, tax, or medical service. Output must be reviewed by a qualified human decision-maker before any action is taken.

8.1 AIIA is a software service

AIIA provides a software-as-a-service platform that produces analytical artefacts using AI models. The Service is general-purpose analytical software for institutional users. It is not:

• investment advice within the meaning of applicable financial regulation, including in particular § 1 Abs. 1a Satz 2 Nr. 1a KWG, § 2 Abs. 2 Nr. 4 WpIG, and § 2 Abs. 8 Satz 1 Nr. 10 WpHG. AIIA does not issue personal recommendations regarding transactions in specific financial instruments based on the personal circumstances of an investor or presented as suitable for an investor;
• investment brokerage, contract brokerage, portfolio management, or any other financial service requiring authorisation under the KWG or WpIG;
• tax advice within the meaning of § 1 StBerG;
• legal advice within the meaning of § 2 RDG; or
• auditing services within the meaning of § 2 WPO.

Where the Customer is itself a regulated firm (e.g., a BaFin-supervised institution, a registered investment adviser, an audit firm, or a law firm), the Customer remains solely responsible for ensuring that its use of the Service is consistent with the rules applicable to its own regulated activity, including conflict-of-interest, suitability, recordkeeping, and supervision requirements.

8.2 AI output is probabilistic, not factual

Output is generated by large language models and may contain errors, omissions, fabrications ("hallucinations"), outdated information, mischaracterisations of source material, biased reasoning, or inconsistent calculations. AIIA designs its orchestration to reduce such risks (cross-model debate, conflict detection, deterministic calculation for financial metrics, Glass Box transparency) but it cannot eliminate them. The Output must be treated as a draft for human review, not as a finished verified work product.

8.3 Human oversight is required

Each Output is presented with a transparency trace ("Glass Box") indicating which models contributed to which decisions. The Customer must ensure that a qualified human reviews the Output before relying on it for any external communication, decision affecting third parties, or commitment of resources. The Customer must not use the Output in a manner that would produce legal effects or similarly significant effects for any natural person solely on the basis of automated processing within the meaning of Art. 22 GDPR.

8.4 No reliance for binding decisions without verification

The Customer acknowledges and accepts that the Output is an analytical aid only. AIIA accepts no liability for decisions taken on the basis of Output that has not been independently verified by a qualified human decision-maker at the Customer.

8.5 EU AI Act

AIIA provides an AI system within the meaning of Regulation (EU) 2024/1689 ("EU AI Act") that incorporates third-party general-purpose AI models via enterprise APIs. In respect of the AIIA orchestration platform itself, AIIA may qualify as a provider of an AI system; in respect of the underlying third-party foundation models, AIIA acts as a deployer and uses the model providers as sub-processors. AIIA does not develop or place general-purpose AI models on the market. The Service is not designed as a high-risk AI system within the meaning of Annex III of the EU AI Act. If the Customer intends to use the Output in a high-risk context (e.g., creditworthiness assessment of natural persons, employment decisions), the Customer is itself a deployer of a high-risk system and is responsible for the obligations that arise. The Customer must inform AIIA in advance of any such intended use, and AIIA reserves the right to refuse such use.

8.6 Investment Analysis, M&A Advisory, and financial-instrument-sensitive outputs

The Service may generate outputs labelled or structured as Investment Analysis, M&A Advisory, Investment Memo, Deal Screening, Target Assessment, Market Analysis, Valuation Analysis, Capital Allocation Support, or similar professional research formats. These outputs are analytical decision-support artefacts for professional review. They may contain analytical conclusions, risk assessments, valuation scenarios, diligence gates, investment-committee-style assessments of whether a transaction is supportable as structured, and conditional decision recommendations concerning process steps, diligence actions, transaction structuring, negotiation positions, and undertaking-level corporate finance matters.

Such outputs do not constitute a personal recommendation to buy, sell, hold, subscribe for, redeem, exchange, repurchase, underwrite, or otherwise transact in any specific financial instrument, crypto-asset, or investment-like instrument. AIIA does not assess whether any transaction is suitable for the Customer's portfolio, mandate, risk profile, financial situation, investment policy, regulatory obligations, or other individual circumstances.

Where an Output concerns securities, funds, bonds, derivatives, crypto-assets, tokenized instruments, Vermögensanlagen, fund interests, or other financial instruments or investment-like instruments, the Customer must treat the Output as non-personal research and analysis only. Final investment, legal, tax, regulatory, and transaction decisions remain solely with the Customer and, where applicable, its licensed advisers.

8.7 Professional use, redistribution, and regulated customers

The Customer represents that it acts in a commercial or professional capacity and that Output will be reviewed by persons exercising independent professional judgment before use.

The Customer must not publish, distribute, forward, or republish Output concerning financial instruments, crypto-assets, issuers, funds, or investment strategies as investment research, investment recommendations, marketing material, or other information recommending or suggesting an investment strategy to third parties or to the public unless expressly agreed in writing with AIIA. Where the Customer does so, the Customer is solely responsible for compliance with applicable laws and regulations, including market-abuse, investment-recommendation, disclosure, conflict-of-interest, and supervisory requirements.

Where the Customer is itself a regulated entity or acts for a regulated vehicle, including without limitation a credit institution, Wertpapierinstitut, financial services institution, AIFM, investment fund, regulated family-office vehicle, audit firm, law firm, or tax advisory firm, the Customer remains solely responsible for its own regulatory obligations, including suitability or appropriateness assessments, outsourcing governance, ICT third-party-risk management, supervision, recordkeeping, conflicts of interest, client communications, and required disclosures. Use of the Service does not constitute outsourcing of a regulated function unless expressly agreed in a separate written agreement.

9. Data, confidentiality, and security

9.1 Data Processing Agreement

Where AIIA processes personal data on behalf of the Customer in the course of providing the Service, the parties enter into a Data Processing Agreement (DPA) under Art. 28 GDPR. The DPA forms an integral part of these Terms. In the event of conflict with these Terms in matters of data protection, the DPA prevails. A current sub-processor list is maintained as an annex to the DPA.

9.2 Customer's controller obligations

The Customer remains the controller of personal data contained in Customer Content. The Customer warrants that it has the legal basis to submit such data to the Service and that it has fulfilled its information obligations toward data subjects.

9.3 Confidentiality

Each party will treat as confidential any information of the other that is marked confidential or that a reasonable recipient would understand to be confidential under the circumstances. Confidential Information includes Customer Content, Output, the Service's non-public technical architecture, commercial terms, security measures, and incident details. Each party will protect the other's Confidential Information with at least the standard of care it applies to its own information of similar sensitivity, and in no event with less than reasonable care.

Confidentiality obligations do not apply to information that: (a) was lawfully known to the recipient before disclosure; (b) is or becomes publicly available without breach of these Terms; (c) is lawfully received from a third party without confidentiality obligations; (d) is independently developed by the recipient without use of the other party's Confidential Information; or (e) must be disclosed under applicable law or binding order, in which case the recipient will, where legally permitted, notify the disclosing party in advance.

Confidentiality obligations survive termination of these Terms for five (5) years; trade secrets within the meaning of the German Trade Secrets Act (Geschäftsgeheimnisgesetz) are protected for as long as they remain trade secrets.

9.4 Security measures

AIIA implements technical and organisational measures as set out in the DPA and in the Privacy Policy, including encryption in transit and at rest, access controls, audit logging, and vendor due diligence. The Customer is responsible for the security of its own endpoints, networks, credentials, and Authorised Users.

10. Fees, billing, and taxes

10.1 Fees

Fees, billing frequency, and currency are set out in the applicable Order Form. Unless otherwise stated, all fees are quoted in Euro (EUR) and are exclusive of VAT and any other applicable taxes, duties, or levies, which the Customer pays in addition where due.

10.2 Payment

Invoices are due net 14 days from the invoice date unless agreed otherwise. Default occurs after 30 days from the due date without a separate reminder (§ 286(3) BGB). On default, AIIA may charge default interest at the statutory rate (§ 288(2) BGB — currently nine percentage points above the base rate for transactions between entrepreneurs) and a default fee of EUR 40 (§ 288(5) BGB). AIIA may suspend the Service after a written warning if invoices remain unpaid after the due date.

10.3 Set-off and retention

The Customer may set off only with claims that are undisputed or legally established, and may exercise a right of retention only insofar as it is based on counterclaims from the same contractual relationship.

10.4 Price changes

AIIA may adjust fees for subscriptions with effect for the next renewal period, with at least 60 days' advance written notice. If the adjustment increases fees by more than 10% over the prior period, the Customer may terminate with effect at the end of the then-current term by written notice within 30 days of receipt of the adjustment notice.

10.5 Usage-based components and overages

Where the Order Form includes usage limits or analysis quotas, AIIA may meter usage and bill overage at the rates set out in the Order Form. The Customer is responsible for monitoring usage by its Authorised Users.

11. Availability and support

AIIA targets high availability of the Service but does not guarantee uninterrupted operation. Planned maintenance is announced where practicable; unplanned downtime, AI Provider outages, and force majeure events are excluded from any availability calculation. Where the Order Form includes a service level agreement (SLA) with specific availability commitments, service credits, or response-time commitments, those commitments are exclusive and constitute the Customer's sole remedy for non-availability.

Support is provided via email at support@aiia.run during business hours (Monday to Friday, 09:00–18:00 CET/CEST, excluding German public holidays), unless an Order Form specifies otherwise.

12. Term and termination

12.1 Term

These Terms apply for as long as the Customer holds an account or has an active Order Form. Subscription terms and renewal mechanics are governed by the Order Form. In the absence of a different agreement, subscriptions automatically renew for periods equal to the initial term unless either party gives written notice of non-renewal at least 30 days before the end of the then-current period.

12.2 Termination for cause

Either party may terminate the agreement for cause without notice (außerordentliche Kündigung) under § 314 BGB if the other party materially breaches these Terms and fails to cure within 14 days of written notice, or if any of the events listed in § 314(2) BGB occurs. AIIA may additionally suspend or terminate immediately if the Customer's use poses a security, legal, or reputational risk that cannot be averted by lesser means.

12.3 Effects of termination

On termination, the Customer's right to access the Service ends. AIIA will, at the Customer's instruction given within 30 days of termination, return or delete Customer Content as set out in the DPA, save where retention is required by law. Fees already paid are non-refundable, except where AIIA has terminated for its own convenience or the Customer terminates for AIIA's uncured material breach, in which case unused prepaid fees are refunded pro rata.

13. Warranties

AIIA warrants that the Service will substantially conform to the Documentation. AIIA will use reasonable efforts to remedy material non-conformities reported by the Customer (Mangelbeseitigung) by way of bug fixes, workarounds, or updates within a reasonable period. Where remediation fails after two reasonable attempts, the Customer may, as its exclusive warranty remedies, reduce fees proportionately (Minderung) or terminate the affected Order Form for cause.

Statutory warranty rights of the Customer remain unaffected to the extent they are mandatory under German law. The strict no-fault liability for initial defects of the rented item under § 536a(1) Alt. 1 BGB is excluded, in line with what the German Federal Court of Justice has accepted for SaaS arrangements in the B2B context.

No warranty as to AI Output. Without limiting Section 8: AIIA does not warrant that the Output will be accurate, complete, fit for any particular purpose, free of errors, or non-infringing. The Customer is responsible for evaluating the Output before relying on it.

14. Limitation of liability

Plain summary. AIIA's liability is fully unlimited only for intentional harm, gross negligence, life/body/health, mandatory product-liability claims, and other items required by German law. For ordinary negligence relating to obligations essential to the contract, liability is capped at the foreseeable, typical damage and at the fees paid in the prior 12 months. For other ordinary negligence, liability is excluded.

14.1 Unlimited liability

AIIA's liability is unlimited:

• for intent (Vorsatz) and gross negligence (grobe Fahrlässigkeit);
• for damages arising from injury to life, body, or health caused by AIIA or its legal representatives or vicarious agents;
• under the German Product Liability Act (Produkthaftungsgesetz);
• under any guarantee (Garantie) expressly assumed by AIIA in writing;
• for fraudulent concealment of a defect;
• where any other mandatory statutory liability cannot be excluded or limited.

14.2 Limited liability for cardinal duties

For slight negligence (einfache Fahrlässigkeit) in breach of a material contractual obligation — that is, an obligation the fulfilment of which is essential to the proper performance of the contract, on whose observance the Customer regularly relies and may rely (Kardinalpflicht) — AIIA's liability is limited to the foreseeable damage typical for this type of contract. In any event, aggregate liability for slight negligence is limited to the total fees paid by the Customer in the twelve (12) months preceding the event giving rise to the claim.

14.3 Excluded liability

Liability for slight negligence in respect of any obligation other than a material contractual obligation is excluded. To the extent permitted by law, AIIA is not liable for: lost profits, lost data (beyond the cost of restoration from a backup the Customer was contractually obliged to maintain), lost goodwill, lost business opportunities, indirect or consequential damages, or punitive damages.

14.4 Customer's contributory fault

§ 254 BGB applies. In particular, the Customer's failure to back up data, the Customer's failure to review Output by a qualified human before relying on it, and the Customer's failure to apply available security measures may constitute contributory fault that reduces or excludes AIIA's liability.

14.5 Limitation period

Claims of the Customer arising from defects of the Service or from these Terms become time-barred twelve (12) months after the statutory limitation period begins, except for claims that may not by mandatory law be subjected to a shorter limitation period (in particular: claims for damages based on intent or gross negligence, claims for injury to life, body or health, and claims under the Product Liability Act).

14.6 Applies to all liability theories

The above limitations apply regardless of legal theory (breach of contract, tort, statutory liability) and benefit AIIA's legal representatives, employees, and vicarious agents in the same way they benefit AIIA itself.

15. Indemnification

15.1 By AIIA

AIIA will defend the Customer against any third-party claim alleging that the Service, when used as permitted by these Terms, directly infringes the third party's intellectual property rights under German or European Union law, and will pay damages and reasonable legal costs finally awarded by a court of competent jurisdiction or agreed in a settlement approved by AIIA, subject to Section 14 and to the Customer (a) notifying AIIA promptly of the claim, (b) granting AIIA sole control of the defence and settlement, and (c) reasonably co-operating with AIIA.

AIIA may, at its option, modify the Service to make it non-infringing, procure the right to continued use, or, if neither is commercially reasonable, terminate the affected Order Form and refund unused prepaid fees pro rata. AIIA has no obligation under this Section 15.1 to the extent the claim arises from Customer Content, the Customer's combination of the Service with third-party material not provided by AIIA, modification by anyone other than AIIA, or use outside the scope of these Terms.

15.2 By the Customer

The Customer will defend, indemnify, and hold AIIA harmless against third-party claims arising from (a) Customer Content, (b) the Customer's or its Authorised Users' use of the Service in breach of Section 7 or of applicable law, (c) the Customer's combination of the Service with third-party material not provided by AIIA, or (d) decisions or actions taken by the Customer on the basis of Output without the human review required under Section 8.

16. Force majeure

Neither party is liable for failure to perform a non-payment obligation to the extent that the failure results from a force majeure event — that is, an event beyond the reasonable control of that party. Force majeure events include: natural catastrophes, pandemics, war, terrorism, civil unrest, governmental action, internet or telecommunications outages of public networks, unannounced large-scale outages of AI Provider services, and cyber-attacks of state-actor scope. The affected party will notify the other promptly and use reasonable efforts to mitigate. If a force majeure event continues for more than 60 days, either party may terminate the affected Order Form by written notice.

17. Compliance with laws

Each party will comply with all applicable laws in performing its obligations under these Terms, including data protection law, EU AI Act obligations applicable to its role, export controls, sanctions (including EU and US sanctions regimes), and anti-bribery laws.

The Customer warrants that it is not, and is not majority-owned or controlled by, a person or entity subject to applicable sanctions, and that it will not use the Service for or on behalf of any such person.

18. Changes to the Terms

AIIA may amend these Terms with effect for the future. AIIA will notify the Customer of material changes at least 30 days in advance, by email or via the Service. If the Customer objects to a material change in writing within 30 days of notice, AIIA may terminate the agreement at the proposed effective date, in which case any unused prepaid fees for the period after termination are refunded pro rata. Continued use of the Service after the effective date constitutes acceptance.

Changes that are favourable to the Customer, that are required by changes in applicable law, or that concern purely operational matters not affecting the contractual balance, take effect upon publication.

19. Governing law and jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and German private-international-law rules that would lead to the application of foreign law.

Exclusive place of jurisdiction for all disputes arising out of or in connection with these Terms is Hamburg, Germany, provided that the Customer is a merchant (Kaufmann), a legal person under public law, or a special fund under public law. AIIA is also entitled to bring proceedings at the Customer's general place of jurisdiction.

Consumer dispute resolution. AIIA does not participate in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) within the meaning of § 36 VSBG, as the Service is offered exclusively to entrepreneurs.

20. Miscellaneous

20.1 Assignment

The Customer may not assign or transfer its rights or obligations under these Terms without AIIA's prior written consent, which will not be unreasonably withheld. AIIA may assign these Terms to an affiliate or to a successor in connection with a merger, acquisition, restructuring, or sale of substantially all of the relevant business.

20.2 Subcontracting

AIIA may engage subcontractors to perform parts of the Service. AIIA remains responsible for their performance and compliance with these Terms and the DPA.

20.3 Notices

Notices to AIIA must be in writing (email to legal@aiia.run suffices), to the addresses in Section 1. Notices to the Customer are sent to the email address last designated by the Customer in its account.

20.4 Severability

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions remain in full force. The invalid provision is replaced by a valid provision that, in economic terms, comes as close as possible to the original intention. The same applies in the case of a gap (Lücke).

20.5 No agency

Nothing in these Terms creates a partnership, joint venture, agency, fiduciary, or employment relationship between the parties. Neither party may bind the other or incur obligations on the other's behalf without prior written authorisation.

20.6 Entire agreement

These Terms, together with the Privacy Policy, the DPA, and any applicable Order Form, constitute the entire agreement between the parties on their subject matter and supersede all prior or contemporaneous communications, whether oral or written.

20.7 Written form

Amendments and side agreements to these Terms must be in text form (Textform, § 126b BGB). This requirement may itself only be waived in text form.

20.8 Language

These Terms are issued in English. Where translations are provided, the English version prevails in case of discrepancy.
