I have a problem. I want to log out of dogfight to allow my brother to play on a separate account but I can't figure out how to do so. If you know how that'd be much appreciated.

you can't. You had to not check the "save my information" option when you logged in. The only way now is removing the game and reinstalling, but you'll lose all "practice" mode data.

Is this android or apple btw?

Im sorry to bring this topic back from the dead, but what if you could save multiple accounts on the same device? You just pressed a button and youre in a different account. Thanks for reading z!
