Terms of Service

Last updated 2 August 2026

These Terms of Service (the “Terms”) govern the paid services offered through openyabby.com (the “Site”).

The Services are provided by IDOV MAMANE, a sole proprietor registered in France and trading under the commercial name OPENYABBY (“OPENYABBY”, “we”, “us”, or the “Provider”).

By purchasing, booking, or using any paid Service, the person or entity purchasing the Service (“you” or the “Client”) confirms that they have read, understood, and agreed to these Terms.

1. The Services

Our paid services consist of setup, configuration, troubleshooting, and advisory assistance relating to OpenYabby and associated development tools (the “Services”).

The Services may be delivered remotely through video calls, voice calls, messaging, screen sharing, or written instructions.

OpenYabby is an open-source software project made available separately under the MIT License. Purchasing the Services does not constitute the purchase of the OpenYabby software itself.

Unless expressly agreed otherwise in writing, our assistance is based on the version, configuration, documentation, and functionality available in OpenYabby’s public repository at the time the Services are performed.

2. Time-Limited Scope

Each Service is limited to the number of hours, half-days, sessions, or other units of time stated when the Service is purchased (the “Purchased Time”). The Purchased Time represents the full scope of the relevant purchase.

Once the Purchased Time has been used, our obligations relating to that purchase are complete, even if the Client’s desired result has not been fully achieved.

Any additional work, revisions, follow-up assistance, or requests falling outside the Purchased Time:

• are not included in the original purchase;
• will be charged separately at our then-current rates; and
• must be agreed upon and paid for before the additional work begins.

Time reasonably spent during a scheduled engagement on troubleshooting the Client’s environment, resolving access issues, waiting for the Client, or addressing third-party service problems counts toward the Purchased Time where those matters are outside our reasonable control.

Unused Purchased Time is not transferable and is refundable only where required by applicable law or expressly agreed by us in writing.

We do not guarantee that any particular feature, configuration, integration, or outcome can be completed within the Purchased Time.

3. Client Prerequisites

The Client is responsible for preparing their own technical environment before the Services begin. Unless expressly agreed otherwise, the Client must have:

• a supported operating system and suitable hardware;
• a stable internet connection;
• administrator or equivalent access to their device;
• a working local coding command-line interface, such as Claude Code or OpenAI Codex;
• all necessary third-party accounts, subscriptions, licences, API keys, and credentials; and
• current backups of all relevant systems and data.

The Client is responsible for all fees charged by third-party providers, including model providers, API providers, hosting providers, software vendors, and subscription services.

The Client must not disclose passwords, private keys, recovery codes, or other highly sensitive authentication information unless disclosure is strictly necessary and an appropriate secure method has been agreed upon.

If the required prerequisites are not available, we may be unable to perform some or all of the Services. Time spent addressing missing prerequisites or related technical problems may count toward the Purchased Time.

4. Scheduling, Delays, and Client Availability

The Client must attend scheduled sessions on time and provide any reasonably required access, information, files, and cooperation.

Where the Client is late, unavailable, or unable to provide the necessary access or materials, the scheduled time may still count toward the Purchased Time.

We are not responsible for delays caused by circumstances outside our reasonable control, including internet failures, third-party outages, platform restrictions, software updates, service discontinuations, or failures affecting the Client’s equipment or environment.

Where we are unable to perform the Services for reasons attributable solely to us, we may, as appropriate, reschedule the affected time, provide replacement time, or issue a partial or full refund.

5. Nature of the Deliverables

Any setup, configuration, code, script, command, documentation, recommendation, or other material provided during the Services is a “Deliverable.” Unless expressly stated otherwise in writing:

• Deliverables are prepared for the Client’s specific environment and circumstances at the time of the engagement;
• Deliverables may require further testing, maintenance, updates, or adaptation;
• compatibility with other devices, environments, software versions, or future updates is not guaranteed; and
• the Client is responsible for reviewing and testing Deliverables before using them in a production or business-critical environment.

To the maximum extent permitted by law, Deliverables are provided on an “as is” and “as available” basis. We do not guarantee that a Deliverable or any associated open-source or third-party software will be uninterrupted, error-free, secure, permanently available, or suitable for every purpose or environment.

Nothing in this section excludes any mandatory legal obligation applying to the performance of the Services, including the statutory guarantees available to consumers under French law.

6. Client Systems, Data, and Backups

The Client remains responsible for their own computers and devices; operating systems and software; accounts and credentials; networks and internet connections; files, databases, and other data; backups and recovery procedures; and security and access controls.

The Client must create adequate backups before, during, and after the Services.

The Client is responsible for deciding whether to run, modify, deploy, publish, or rely upon any Deliverable, command, configuration, or open-source software discussed during the Services.

We are not responsible for the acts, omissions, pricing, availability, security, changes, outages, or discontinuation of any third-party software, model, API, platform, or service.

7. Limitation of Liability

Nothing in these Terms limits or excludes liability where doing so would be unlawful, including liability arising from fraud, wilful misconduct, or any other liability that cannot legally be limited or excluded.

Subject to the preceding paragraph and to the maximum extent permitted by applicable law, we will not be liable for:

• loss, deletion, disclosure, or corruption of data;
• damage to hardware, software, accounts, networks, or systems;
• security incidents or unauthorised access;
• business interruption or downtime;
• loss of revenue, profits, contracts, opportunities, customers, or anticipated savings;
• costs incurred in obtaining replacement services;
• failures caused by third-party software, services, APIs, models, or platforms; or
• indirect, incidental, special, consequential, exemplary, or punitive damages.

To the maximum extent permitted by applicable law, our total aggregate liability arising out of or relating to a particular Service will not exceed the amount actually paid to us for the specific Service giving rise to the claim.

This limitation applies regardless of the legal basis of the claim, but does not restrict any mandatory consumer right or remedy.

8. Services Only

The Client is purchasing our time and expertise. The Client is not purchasing:

• ownership of the OpenYabby open-source project;
• an exclusive licence to the project;
• a guaranteed technical or commercial result;
• ongoing maintenance or support beyond the Purchased Time; or
• any third-party product, account, subscription, or licence.

The OpenYabby software remains governed by its applicable open-source licence. Third-party software and services remain governed by the terms and licences imposed by their respective providers.

9. Prices, Payment, and Taxes

Prices are displayed before purchase. Payments are processed through Stripe or another payment provider identified during checkout; the payment provider’s own terms and privacy practices may also apply.

Applicable taxes, including French value-added tax where required, will be displayed or added in accordance with applicable law.

The Client is responsible for any bank fees, foreign-exchange charges, card-provider fees, or other transaction costs imposed on the Client’s side.

Unless otherwise stated, payment must be received in full before the Services begin.

10. Consumer Right of Withdrawal

This section applies only where the Client is acting as a consumer and has a mandatory right of withdrawal under applicable consumer law.

A consumer purchasing a Service remotely may generally withdraw from the contract within 14 days from the date on which the contract is concluded, without providing a reason, subject to applicable legal exceptions.

Where the Client asks us to begin performing the Services before the end of the withdrawal period, the Client must make an express request for early performance.

If the Client withdraws after performance has begun at their express request, the Client may be required to pay an amount proportionate to the Services performed before the withdrawal was communicated.

Where the Service has been fully performed before the end of the withdrawal period, the right of withdrawal may be lost only where the applicable legal requirements have been satisfied, including the Client’s prior express request and acknowledgement where required.

To exercise a statutory right of withdrawal, the Client must send a clear statement of their decision to withdraw to the contact details in Section 16 before the applicable deadline.

11. Cancellations and Refunds

Except for mandatory withdrawal, refund, or other consumer rights under applicable law, payments are non-refundable once the Services have been performed or the relevant Purchased Time has been reserved and used.

A Client may request that we consider a refund where a genuine problem has occurred, including where Services could not be delivered for reasons attributable solely to us. Any voluntary refund:

• is considered individually;
• may be full or partial;
• may take into account work already completed and costs already incurred; and
• will not, in any case, exceed the amount actually paid for the Service concerned.

A request for a voluntary refund must be submitted within 14 days after the relevant Service and must clearly describe the issue. Submitting a refund request does not, by itself, create an entitlement to a refund. Any statutory right of withdrawal or mandatory legal remedy remains unaffected.

12. Client Responsibilities

The Client agrees to:

• provide complete and accurate information;
• cooperate reasonably and provide timely access where required;
• comply with all licences and terms applicable to third-party software and services;
• use the Services and Deliverables lawfully;
• review and test Deliverables before production use;
• maintain appropriate backups and security measures;
• avoid using the Services to infringe third-party rights or break applicable law; and
• avoid representing that we endorse, certify, sponsor, or guarantee the Client’s own product or service.

The Client must not resell the Services as though they were performed directly by OPENYABBY without our prior written agreement.

13. Intellectual Property

OpenYabby and any other open-source components remain subject to their respective open-source licences. Each party retains ownership of intellectual property it owned before the engagement.

Unless expressly agreed otherwise, the Client may use Deliverables created specifically for the Client for their own personal or internal business purposes, subject to:

• any applicable open-source or third-party licences;
• payment in full for the relevant Services; and
• any restrictions communicated before or during the engagement.

No trademark rights, ownership of the OPENYABBY name, or rights in our pre-existing materials are transferred to the Client.

14. Third-Party Names and No Affiliation

OPENYABBY and the Services are independent. We are not affiliated with, endorsed by, sponsored by, or acting on behalf of Anthropic, OpenAI, Stripe, or any other third party unless expressly stated otherwise.

All third-party names, trademarks, product names, and logos belong to their respective owners. References to third-party tools are provided solely to identify compatibility, dependencies, or possible technical options.

15. Complaints

If you have a complaint, please contact us first using the details in Section 16 so we can try to resolve it directly and in good faith. We will acknowledge your complaint and work with you toward a fair resolution.

Where you are acting as a consumer, this does not affect any additional out-of-court dispute-resolution right that applicable consumer law may grant you.

17. Governing Law and Jurisdiction

These Terms are governed by French law.

Where the Client is acting in the course of a trade, business, craft, or profession, any dispute arising from or relating to these Terms will be submitted to the competent French courts, subject to any mandatory procedural rule.

Where the Client is acting as a consumer, nothing in these Terms deprives the Client of any mandatory protection provided by the law of the country in which the Client habitually resides, or of the right to bring or defend proceedings before any court having jurisdiction under applicable consumer law.

18. Changes to These Terms

We may update these Terms from time to time. The version applicable to a purchase is the version made available to the Client at the time the relevant order is placed, unless a change is required by law or expressly accepted by both parties. The “Last updated” date at the top of these Terms indicates when the latest revision was published.

19. Severability

If any provision of these Terms is found to be invalid, unlawful, or unenforceable, that provision will be applied to the maximum extent permitted by law or, where necessary, treated as removed. The remaining provisions will continue to apply.

20. Entire Agreement

These Terms, together with the order description, checkout information, and any written terms expressly agreed for a particular engagement, constitute the entire agreement relating to the relevant Services. If there is a conflict between these Terms and specific written terms agreed for a particular Service, the specific written terms will prevail for that Service.
