Terms and Conditions

These terms govern the use of the capsul.chat site and of the capsul command-line tool, as well as the sale of the related subscriptions. The service is published by Adrien Pennetier, sole trader (“PENRA”), whose details appear in the legal notice (hereinafter “the Publisher”).

Creating an account or subscribing entails unreserved acceptance of these terms, in the version in force on the relevant date.

capsul is a tool that optimises the context sent to AI programming agents (Claude, Codex) in order to reduce their consumption. It is installed and runs on the user's machine; the site allows management of the account, linked terminals and subscription.

The service may evolve. The Publisher may enrich or reorganise its features, without this degrading the essential characteristics of the plan subscribed to. Any substantial change to the characteristics of a paid plan is notified to the subscriber by email at least thirty (30) days before it takes effect, together with a statement of their right to terminate free of charge within that period; where termination occurs on that basis, the paid and unused portion of the subscription is refunded pro rata temporis.

Access may be interrupted for maintenance; such interruptions are, as far as possible, announced in advance and limited to the strictly necessary duration. Interruptions and unavailability do not affect the rights a consumer holds under articles L224-25-12 et seq. of the French Consumer Code, in particular the right to have the service brought into conformity, to a price reduction or to termination of the contract.

Access to account-related features requires registration, by email address or through an identity provider (Google, GitHub). The user warrants the accuracy of the information provided and keeps their means of access confidential.

Creating an account is reserved for people aged at least fifteen (15), the threshold set by France under article 8 GDPR.

Actions carried out from a linked terminal are presumed, until proven otherwise, to have been performed by the account holder. That presumption does not apply where the use results from identity theft, from a compromise of the Publisher's systems, or from the Publisher's own fault; in the event of a dispute, it is for the Publisher to establish who is responsible for the action in question. The user informs the Publisher without delay of any unauthorised use of their account, at contact@capsul.chat, and may immediately revoke any terminal from the “Terminals” area, which shows the date each was last used. The service keeps no log of prompts: there is therefore no usage record more detailed than that date, and the Publisher cannot produce one.

A linked terminal remains authorised until it is revoked from the account's “Terminals” area.

The service is offered under the following plans:

Prices are shown in euros. As the Publisher benefits from the VAT exemption scheme, the statement “VAT not applicable, article 293 B of the French tax code” applies: no VAT is charged. The prices displayed at the time of the order prevail; the Publisher may change them at any time, with the rates in force during a subscription remaining applicable until it expires.

• Free, ten trial prompts, no card required.
• Pro, €5.99 per month (launch offer; original price €9.99), unlimited prompts.
• Team, priced per seat, from €20.99 per month (15 seats included, then €3.50 per additional seat up to 30; beyond that, on request).
• Annual billing may be offered with a 17% discount compared with the monthly rate.

Subscription takes place online. Payment and subscription management (payment method, invoices, termination) are operated by our payment provider Polar (Polar Software Inc.), which collects on the Publisher's behalf. No card details are entered or stored on the Publisher's servers.

The subscription takes effect as soon as payment is validated and renews automatically each period (monthly or annual) until terminated.

The subscription is entered into for the chosen period and is tacitly renewed at each expiry. The user may terminate at any time from the management portal (accessible from the Billing page): termination takes effect at the end of the period already paid for, without refund of the remaining time, and paid access is maintained until that date.

This principle does not apply to termination exercised following a substantial change to the characteristics of the plan (article 2): in that case, the paid and unused portion of the subscription is refunded pro rata temporis.

The Publisher may suspend or close an account in the event of a breach of these terms or of abusive use.

Under articles L221-18 et seq. of the French Consumer Code, a consumer has in principle fourteen (14) days to withdraw.

As the service consists of digital content and a service performed immediately, a user who subscribes expressly requests immediate performance of the service and acknowledges that they lose their right of withdrawal as soon as performance begins, pursuant to article L221-28 of the same code.

The Publisher is liable, under general law and under articles L224-25-12 et seq. of the French Consumer Code, for breaches of its own obligations to supply a conforming service, including the availability of the site, of the account and terminal management area, and of the interfaces it operates. No provision of these terms has the object or effect of limiting or excluding that liability, nor the consumer's right to compensation for any loss suffered as a result.

capsul runs on the user's machine and drives third-party artificial intelligence agents (Claude, Codex) that the user subscribes to and authenticates with directly with their own publishers. The Publisher does not supply those agents and is not liable for their availability, their pricing or the results they produce. capsul does not replace the user's own judgement about the code produced, which it is for the user to review and test before any deployment to production.

The legal guarantees of conformity for digital content and digital services (articles L224-25-12 et seq. of the French Consumer Code), the legal guarantee of conformity for goods (articles L217-3 et seq.) where applicable, and the guarantee against hidden defects (articles 1641 et seq. of the French Civil Code) apply as of right to consumers.

The processing of personal data is described in the Privacy Policy, which forms an integral part of these terms.

These terms are governed by French law. In the event of a dispute, the user first contacts the Publisher (contact@capsul.chat) to seek an amicable solution.

However, where the user is a consumer habitually resident in another State, the choice of French law may not result in depriving them of the protection afforded by provisions that cannot be derogated from by agreement under the law of their country of habitual residence, in accordance with article 6(2) of Regulation (EC) No 593/2008. A consumer domiciled in a Member State of the European Union may bring proceedings, at their choice, before the courts of their domicile or those of the Publisher's domicile; the Publisher may bring proceedings against them only before the courts of the Member State where they are domiciled, in accordance with articles 17 to 19 of Regulation (EU) No 1215/2012.

Under articles L611-1 et seq. of the French Consumer Code, a consumer may use a consumer mediator free of charge with a view to the amicable resolution of a dispute with a trader.

Version 1.0, in force as of 30 August 2026.
