I bought something and didn't get it
Close the game and open it again. A purchase that didn't finish arrives the next time the game starts, and a payment that is still pending arrives once it clears. Mastermind comes back by itself, or with Restore purchases in Settings.
I got a new phone
Mastermind comes back on any phone signed in to the same store account, by itself or with Restore purchases in Settings. Your company is saved on your old phone only.
How do I change my choices about ads and privacy?
Open Settings and tap the shield. The shield is there in countries whose law asks for it.
How do I delete my data?
Uninstalling the game deletes everything it keeps on your phone. To have anything else deleted, write to us. Our privacy policy explains what the game collects.
