Privacy Policy

1. Information We Collect

Account Information

When you sign up, we collect your name, email address, and a hashed password. We use Firebase Authentication to manage your credentials securely.

Usage Data

We track study activity including flashcards generated, quizzes taken, quiz scores, groups joined, and messages sent within study groups. This data powers features like progress tracking and spaced repetition.

Uploaded Content

Files uploaded to study group chats (images, documents) are stored in Firebase Storage and are only accessible to members of the relevant study group.

Analytics

We use Google Analytics to understand how visitors use our site. Google Analytics collects anonymized data including pages visited, time on site, and approximate location. No personally identifiable information is shared with Google.
