Creating an optional account (email and password) unlocks AI scoring and keeps your Pro subscription tied to you; that adds a small profile — your email, name, and study preferences — on our secure Supabase backend. The app has no ads, analytics, or tracking, and you can permanently delete your account and its data from inside the app at any time.

Study data you created as a guest lives only on your device and is removed by resetting or uninstalling the app.
