Your data

Without an account, nothing about you is sent to us: your lesson results stay in your browser (its “local storage”), and you can erase them by clearing this site's data.

With an account, we keep your email address (to sign you in) and your lesson results (score and date, to show your progress on any device). That's all: no name, no tracking, no ads, and nothing is sold or shared.

They are stored by Supabase, our database and sign-in provider, which also sends the sign-in emails. We keep them until you delete your account, which you can do at any time from your account page: it erases everything right away. The legal basis is providing the service you ask for (GDPR, art. 6(1)(b)).

Cookies: only the ones needed to keep you signed in. No analytics or advertising cookies, so there is no consent banner.

Your rights: you can access, correct, export or erase your data, and object to its use. You can also complain to the French data protection authority, the CNIL.
