Privacy Policy

What we store

Your account (email address and password), your learning data (cards, reviews, study progress), and your conversations with the AI tutor. We store this data to run the app for you — nothing else.

What we share

Payments are handled by Paddle (on the web) and Apple (on iOS) — we never see your card details. The text you send to the AI tutor is processed by AI providers to generate answers. We do not sell your data and we show no ads.

Your data is yours

You can export your cards and learning data at any time. If you delete your account, we delete your data.
