Your knowledge. Your privacy.

What we collect

We store your email, password hash, username, chosen city and avatar, account sessions, game answers, scores and essential first-party activity events. We use these to run games, keep rankings fair, recover accounts and understand participation. We do not use advertising trackers.

What other players see

Public profiles show usernames, city and scores. Email addresses and authentication data are never public. Turn off public profile visibility in Settings to appear as a private player on rankings.

Cookies and security

Essential HttpOnly cookies keep you signed in or preserve guest practice ownership. Database-backed rate limits store hashed request identifiers for short periods. Service workers cache only public static assets, never game questions or authenticated API responses.

Your choices

Request an account data export or deletion through Settings. An administrator reviews requests and applies the approved retention policy. Final response timelines and privacy contact details must be supplied by the operator before launch.

Service providers

The application and PostgreSQL database are hosted on Railway. Transactional email and encrypted backup storage providers must be documented before launch. No sale of personal information is intended.

Young players

Minimum age, consent requirements and related safeguards have not been finalized. Public marketing must wait for legal review.
