This policy explains what information the Adin Quiz Master app (published by Amer InfoTech) collects, how it is used, and your choices.
Information we collect
When you create an account, we collect:

As you play, we also store your quiz scores, game results, match ratings and match history, because these power the rankings and leaderboards.
