Last updated: February 10, 2026
1. Information We Collect
Account Information: Name, email address, and authentication data when you create an account (directly or via Google OAuth).
Documents: Files you upload for processing. These are stored securely in Supabase Storage and are only accessible to you.
Usage Data: Session duration, learning progress, and interaction patterns to improve the Service.
2. How We Use Your Data
- Provide and improve the AI learning experience
- Process payments through Stripe
- Send transactional emails (receipts, notifications)

3. AI Processing
Your documents are processed by Google's Gemini AI to enable interactive learning. Document content is sent to Google's API during active sessions. We do not use your documents to train AI models. Session transcripts are retained for up to 5 sessions, then summarized and deleted.
4. Data Storage & Security
Data is stored on Supabase (PostgreSQL) with Row Level Security policies. All connections use TLS encryption. Payment information is handled exclusively by Stripe — we never store card details. API keys and secrets are stored in environment variables, never in code.
