Your privacy matters.

This preview version uses Supabase for account identity and saved learning records. Authored practice does not send your choices to an AI model.

Temporary introduction checkpoints expire after 30 minutes. They contain choice IDs and an optional nickname, with no passwords, payment details or private conversations.

Your own profile, badges, XP and saved checkpoints are available from your account. Marketing consent is separate from creating an account.

The full privacy policy, retention schedule and contact details must be approved before public registration opens.
