Privacy and minimum age

No accounts or emails. We store your name, answers, any location you choose to send and game progress in the room record; that record is not deleted automatically. Photos and audio are deleted 24 hours after the game ends, checked every 10 minutes.

Google AI judges photos and audio and may process game answers. Don't send sensitive information or photos of other people without their permission.

Minimum age: 13. Under-13s play with an adult and with parental permission. If you're under 18, ask your parents for permission.

Contact and requests about your data: apps@brainystack.co.

Fandom Night rooms are public: other fans see your generated nickname (fandom, emoji and number), answers and points. We do not ask for names, photos or audio, and there is no open chat. We publish fandom results only after at least 3 games and 10 distinct anonymous players, retained for 90 days. These are game results, separate from K-Pop Arena votes.

App and optional notifications

Installing the app is free and playing requires a connection. The app does not save offline copies of games, answers or photos.

The Android app (Brainy Games on Google Play) opens this same website: it asks for no extra permissions, has no ads or purchases, and the 18+ room is not offered inside it.

Only if you tap the notifications button after a challenge and accept the browser permission, we store the push delivery address (endpoint), two subscription keys, language and signup date. We do not link these to your name, answers, fandom or room. The IP is used only in memory for one minute to limit abusive signups.

Starting the next day, we send at most one daily notification for the new challenge, from 00:05 UTC. Your browser’s push provider processes delivery; the message is encrypted. Receipt time may vary.

To delete the subscription from our server, tap “Turn off notifications” on the challenge result screen. You can also revoke permission in browser settings; if the provider reports that the subscription expired, we delete it automatically. Until then, it is stored only for this notification. If you are a minor, ask your parents for permission.
