Privacy Policy
Last updated: October 12, 2026
This policy explains what information Adin Quiz Master ("we", "the app") collects when you use our website or Android app, how we use it, and how you can request it be deleted.
Information we collect
When you create an account, we collect:
- Username - shown on leaderboards and to opponents in live matches
- Email address - used to log you in and to send password-reset emails

- Age and country - used to show region-relevant quiz content and country flags on leaderboards
As you play, we also store your quiz scores, game results, PvP ratings, and match history, since these power the rankings and leaderboards.
