Privacy

This policy is awaiting publisher contact details. Public release is not available until those details are confirmed.

Your account and learning

Guests can use free lessons without an account. When you sign in, Supabase processes your email address, authentication details, display name, timezone, and learning progress so your learning follows you across devices. Native sign-in tokens are stored in secure device storage. Web sessions use secure cookies in production.

Payments and diagnostics

Stripe processes web payments. Superwall presents App Store offers and handles purchases and restores; Apple processes and verifies those App Store transactions. We link purchase access to your account ID; we do not receive your full payment card details. We do not use third-party error tracking or advertising trackers.

Device storage

The iOS app stores queued progress and opened lessons for offline learning. Paid lessons and recordings remain available for up to seven days after access verification. Signing out removes personalized caches. Clearing device storage may remove progress that has not synchronized.

Retention and deletion

Learning data is kept while your account exists. You can delete your account in settings. Learning records are deleted and retained billing records are detached from your account. Payment providers may retain transaction records under their own legal obligations. Deletion does not cancel an Apple or Stripe subscription; cancel it separately to stop renewal.

Your choices

You can learn as a guest, edit your display name, sign out, or delete your account. Contact the publisher for questions, access requests, or corrections. This policy must be reviewed whenever the app’s data practices change.
