Privacy Policy

Files you upload: When you upload PDF or PowerPoint files, we securely store and process them to extract text and images for flashcard generation. Files and extracted content may remain associated with your generation history, course workspaces, source evidence, or saved decks so those features remain resumable and available when you return.

Account information: If you create an account via Google Sign-In, we store your email address and name to identify your account and saved decks.

Usage analytics: We use PostHog to collect anonymous usage data to improve our service. This includes pages visited, features used, and general interaction patterns. No personal content from your files is included in analytics.

Uploaded files, extracted source content, card data, review decisions, and associated images are stored in Supabase (our database provider). Access is restricted to the account or browser session that created the job. Raw lecture and card content is not included in PostHog analytics.

We do not sell or rent personal information or lecture contents. If you explicitly opt in to trusted-card contribution, approved text cards may be de-identified and considered for reuse. Lecture files, images, source excerpts, and your identity are not contributed. A contributed card needs independent approval from multiple students and fresh grounding in the receiving student's source before it is eligible for reuse. You can leave this option off and still use the service.

You can delete your saved decks at any time from your library. To delete your account entirely, contact us at the email below.

If you use the service without an account, durable jobs are associated with a private browser device identifier rather than an email address. To request deletion of an account, course workspace, durable generation data, or a trusted-card contribution, contact us at the address below.
