I want to use the Google Play Store, so I need to login with my Google account. The moment you login, Android will store your Google account, so apps like Gmail can access it.
However, the Play Store is the one and only app I want to use my Google account with. I don't want Gmail or anything else to access or even know that I have a Google account.
Is there a way to isolate my Google account to just the Play Store? Is my only option to make a dummy Google account just for this device?
I'm running Android 7.0.
