If you remove a game app in Google Plus, does your game account and game data get removed from the game's database? Or does it depend on the game's publisher?I wonder what's Google Plus's policy about my inquiry.
What happens if you remove a game app on Google Plus?
google plus;games
It depends on the creator of the game.If the game developer has created an account for you on their own systems, removing permissions for a game doesn't necessarily delete your account with them. You'll need to contact the developer if you want them to remove your account or delete information they have stored about you. To find developer contact information, we suggest visiting the game developers website.Source: Removing permissions for a game
