Privacy Policy
This private beta is designed to collect as little personal information as practical.
What Is Stored
The app stores your username, password hash, invite/account records, training settings, puzzle sessions, move timings, puzzle results, study-day selections, written reflection notes, guess-the-move notes, and account/session cookies. It does not require email.
Security Logs
The app may store limited security events such as login failures, signup failures, and rate-limit events. IP addresses are hashed before storage where practical.
What Is Not Used
No advertising, tracking pixels, third-party analytics, or intentional sale/share of user data are part of this app.
Cookies
Cookies are used for login sessions and CSRF protection. They are necessary for the app to work.
Children
The app is not intended for children under 13. Do not create an account if you are under 13.
Deletion and Export
During the beta, account export and deletion are handled manually by the site operator using the admin tools.
