Offline Play stays on your device. It does not need an account and does not send game results for Gold, Silver, Bronze, or the Daily Winner.
If you create an account, the server stores your username, optional email/phone, game history, competition coins, purchases, friends, and reports. Daily Winner payment proof is uploaded only by administrators.
During an online human vs human match, the app may use the microphone so players can talk. Voice audio is sent to the game operator's voice server for that match only. You can mute your microphone or speaker at any time. Offline Play never uses the microphone.
Purchases never grant Gold, Silver, or Bronze. Ads never grant those coins.
Contact the operator to request account deletion.
