Privacy Policy

Last updated: April 28, 2026

What we collect

Account email, lecturer-provided class and student names (we recommend pseudonyms), scanned page images, OCR/clarity/translation outputs, and usage events for billing.

How student data is stored

Student work is stored in private Supabase Storage buckets. Access is gated by row-level security and short-lived signed URLs. We never expose student work via public URLs.

How AI is used

Text extracted from scans is sent to large language models via the Cien Rios AI proxy for readability cleanup and (optionally) translation. We do not use student work to train models.

Your controls

• Anonymous mode for student folders.
• Export your data on request.
• Delete your account and all owned organization data — see Settings → Delete my data.
