Cookie policy

Essential authentication cookies

We use Supabase authentication cookies to hold your session and refresh it securely. They are necessary when you log in and sync learning activity. Guest quizzes do not require an authentication cookie. Signing out ends your session; you can also clear cookies in your browser.

Your browser settings

Blocking authentication cookies may prevent login or saved progress from working. Public lessons, quizzes and flashcards remain available without an account. Guest progress uses localStorage on this device only; clearing site data removes it.

Advertising and analytics cookies

No advertising or analytics scripts are enabled in this version. We do not show a misleading consent banner for services that are not running. If optional tracking is added, the site will provide the required notice and consent controls before loading it.

Updates

We will update this page when the use of cookies changes. Read the privacy policy for the account information we store.
