What data is stored

When you answer questions, the site sets a random identifier in a cookie and stores your answers, the hints you used and your progress. Signing in stores your email address. A class teacher sees only your answers on topics assigned in that class after you joined. IP addresses and browser details are not stored in the database. Data is stored on servers in Russia (Selectel, Moscow); backups are encrypted.

The full personal data policy is being published. Requests for access or deletion: privacy@biased.school
