Who processes your data?

What this website stores

The website stores the information needed for your account: name, email, language, a password hash, verification dates and a phone number if you choose to confirm it. It also stores subscription references and statuses, acceptance of terms, contact or withdrawal requests and limited security logs.

Working documents, case files and AI conversations belong to the separate SaaS workspace and are not stored in this website’s customer database. Their processing and retention rules are specified in the relevant workspace agreement.

For which purposes?

Account management, subscriptions, billing and support are based on preparing or performing the contract. Accounting and legal obligations justify required retention. Abuse prevention and account protection rely on our legitimate interest. An optional phone number is used for the requested verification and any separately agreed use. No automated marketing is enabled by default.

Service providers and payments

Payment takes place on a Stripe page. This website does not receive full card numbers. Stripe processes the information required for payment and billing under its own terms and applicable agreements.

Service emails are delivered by the configured provider: OVHcloud.

The providers, processing locations and transfer safeguards must match the actual configuration. Providers may process data outside the European Economic Area; applicable safeguards are specified in the relevant processing agreements. The website therefore does not make a blanket promise of no international transfers.

Cookies and preferences

A session cookie supports sign-in and form protection. It is necessary for account functionality. Your theme preference may be stored locally in your browser. The delivered website includes no advertising or audience analytics tools. Stripe-hosted pages follow their own cookie notices.

Retention

Contact requests are retained for up to 12 months after the last recorded exchange, unless a contractual relationship or obligation justifies another period. Account data is retained during the service relationship and then according to applicable obligations. Order, billing and consent evidence may need to be retained after account closure. Temporary tokens expire and are purged; backup retention is defined by the operator.

Your rights

You may request access, correction, erasure, restriction or portability of your data, and object to certain processing under applicable conditions. Contact the privacy address above. You may also contact the competent supervisory authority, including the CNIL in France.
