Your sources are private by default.

We store the study material you save, your cards, review schedules, quiz results, details of how each deck was made, and your settings, so your library works across devices.

Who helps us run it

We use service providers for sign-in and cloud storage, hosting, privacy-friendly analytics, error monitoring, and email delivery for contact replies and the daily study reminders you turn on.

Optional AI generation

The standard private engine does not send your source to an AI provider. Only if you choose AI generation and confirm, your source is sent to an AI model provider to make that deck.

Copy in your browser

This browser may keep a copy of your recent library so you can open it during a short outage. Signing out does not delete your cloud data. Deleting your account removes both.

Your choices

From Settings you can export a deck or your whole account, turn off reminders, delete decks, or permanently delete your account. We do not sell personal data or study content.
