Privacy

Recall Engine is built around private lecture uploads and user-owned generated outputs.

Account data

Recall Engine uses email and password authentication. Profile records store your name, avatar, credit balance, and basic academic details you choose to provide.

Lecture files

Uploaded lecture files and extracted page text are stored on your account. They are used to generate study outputs and are not shared.

Quiz and weakness data

Wrong answers submitted during practice sessions are stored in your account to power Weakness Review and targeted revision packs. This data is visible only to you.

Access controls

The database is designed so users can only access their own lectures, pages, generations, transactions, and question history.

Payment data

No payment data is collected yet. Paid features are not active. When payments launch, billing will be handled by a third-party provider and card details will not be stored on our servers.

Server-side secrets

Supabase secret keys, Gemini API keys, and prompt templates belong on the server and are never exposed to browser code.
