Your privacy matters to us. This policy explains what data we collect, how we use it, and your rights regarding your information.
1. Information We Collect
Account info (email, name) via Google OAuth or email sign-up. Decks and cards created from your content, plus practice data (accuracy, WPM, session history). Basic usage analytics (page views, feature usage). Payment info is processed by Stripe — we do not store your card details.
2. How We Use Your Data
To provide and improve the Service. To save your decks, track progress, and sync across devices. To process payments for Pro subscriptions. We do not sell your personal data to third parties.
3. Data Storage
Your data is stored securely using Supabase (hosted on AWS). Flashcard data and practice records are associated with your account. Guest data is stored locally in your browser only.
4. Cookies & Local Storage
We use local storage to save your preferences (theme, language, font size). Authentication tokens are stored securely. We do not use third-party tracking cookies.
5. Third-Party Services
Google OAuth for authentication. Stripe for payment processing. Supabase for database and auth. These services have their own privacy policies.
