What we collect
Your email address (used only to sign you in), profile fields you enter (username, city, state/region, country), study activity (card reviews and scheduling), and content you upload.
What we never do
We don't sell your data. Your study progress and card edits are private to you and never shared with other users.
Third parties
Supabase (database, authentication and file storage), Stripe (payments) and Resend (transactional email). Optional AI deck assessment sends sampled deck content and inspection evidence to the configured provider, Anthropic or OpenRouter. Card generation takes place separately at swankicardsmaker.com; review that service's privacy notice before submitting sources there.
Retention & deletion
Email us to delete your account. Uploaded public decks are attributed to you and may remain after deletion; personal data (profile, study state, edits) is removed.
