Terms of service

1. What these terms cover

These terms form the contract between you and Quavern, SASU, 14 Rue de Menespey, 33185 Le Haillan, France, for the use of the myQuavern account space, the Marl assistant, the Marl API, the Marl Code application and the online services of the QuavernOS operating system, together with the Quavern websites.

Marl Code binaries come with their own licence file; it applies alongside these terms. QuavernOS is built on NetBSD and other open-source components: each keeps its own licence, and for the software itself the licences shipped with the system prevail. Enterprise customers with a signed agreement follow that agreement where it differs from this page.

This page is dated and versioned. If a change matters, subscribers are informed before it takes effect; continuing to use the services after that date means accepting the new version.

2. Your account

You need a myQuavern account to use Marl. The information you give must be accurate, and the credentials are yours to keep safe: actions taken with your account are treated as yours. One person, one account.

The services are intended for people aged 15 or over; under that age, a parent or guardian must agree. An organisation administrator manages the organisation's seats, tokens and access, and is responsible for who they admit.

3. Plans and prices

What each plan includes, and its price, is shown on the product pages and at checkout before you pay. Quotas are measured in usage credits over rolling windows; the exact remaining amounts are always visible from your account.

Quavern can change plans and prices for the future. A price change for an existing subscription is announced at least one month before it applies, and you can cancel before it does.

4. Payment, renewal and trials

Payment is handled by Stripe. Subscriptions are monthly or annual and renew automatically until cancelled. The subscription state recorded by the payment processor is authoritative.

Where a free trial is offered, its length is stated at checkout. A trial can be cancelled at any moment before it ends without being charged; otherwise the paid period starts when the trial ends. A given trial is available once per account.

Team plans require a minimum of five seats. Enterprise plans are set up by contract, without self-serve checkout.

5. Right of withdrawal (EU consumers)

If you subscribe as a consumer, you normally have 14 days to withdraw. The services are digital services that begin at once: by subscribing, you expressly ask for immediate performance and acknowledge that you lose the withdrawal right once the service has been fully performed, as article L221-28 of the French Consumer Code provides.

You can still cancel the subscription itself at any time for the next period, as described below.

6. Cancelling and ending the contract

You can cancel online at any time from the billing page of your account, in a few clicks and without calling anyone. Cancellation takes effect at the end of the period already paid; access continues until then.

Quavern can suspend or end an account for a serious breach of these terms, for unpaid amounts, or for abusive use, with notice proportionate to the situation except where urgency requires acting at once. You can export or delete your data from the account before closing it.

7. Acceptable use

Use the services lawfully and respectfully. In particular, do not:

• use them for illegal activity, or to create or spread content that harms others;
• try to bypass quotas, security measures or access controls;
• resell access, share paid credentials, or extract content in bulk by automated means outside the documented API;
• disrupt the service or other people's use of it.

Automated safeguards can block prohibited use. Every refusal carries a stable support code, and you can contest a decision by writing to hello@quavern.com.

8. Your content and Quavern's software

What you write and upload stays yours. You give Quavern only the licence needed to operate the service: storing your content, moving it through the systems that produce replies, and showing it back to you. Replies generated for you are yours to use, to the extent the law allows.

Quavern's software, names and designs remain Quavern's. Open-source components are governed by their own licences; Marl Code is proprietary and distributed as binaries.

Feedback you choose to send may be used to improve the services, without obligation or compensation.

9. AI answers

Marl generates answers with artificial intelligence. Answers can be incomplete or wrong, and they are not medical, legal or financial advice. Check anything important before acting on it, especially code you run and decisions that affect other people.

10. Availability and support

Quavern aims for a reliable service but provides it as is, without a guaranteed availability level unless an Enterprise agreement states one. Planned maintenance is announced when it is likely to be noticed.

Support is provided by e-mail at hello@quavern.com, with priority handling for the plans that include it.

11. Liability

Nothing in these terms removes rights that the law gives consumers, or limits liability that cannot be limited, such as liability for gross negligence or wilful misconduct.

For business customers, Quavern's total liability for all claims in a contract year is capped at the amounts paid for the services during the twelve months before the event, and indirect damages, lost profits and lost data are excluded to the extent the law permits.

12. Personal data

How Quavern processes personal data is described in the Privacy policy, which is part of the information given to you under these terms.

13. Consumer mediation and disputes

If something goes wrong, write first to hello@quavern.com; most issues are resolved directly. If a written complaint does not resolve the issue, consumers in France can use consumer mediation free of charge. The contact details of the mediator Quavern is appointing will be published on this page; consumers can also use the European online dispute resolution platform at ec.europa.eu/consumers/odr.

These terms are governed by French law. Disputes with business customers come before the courts of Bordeaux; consumers keep the jurisdiction rules the law gives them.

14. Miscellaneous

If one clause of these terms turns out to be invalid, the others keep their effect. Not enforcing a clause on one occasion does not waive it. Quavern may transfer the contract as part of a change in the company's structure; you are informed when that happens.

Notices are sent to the e-mail address of your account. The French version of this page prevails over the English one.
