OK I just made a very strange discovery.
Lets say I have a calendar app and a game, both with paid for attributes on my old android phone. I am NOT logged into google store nor do I have a google account on my graphene phone.
When I load those two apps onto my graphene phone, the paid for attributes are missing, as they are tied to my google account. This is to be expected.
Firstly when i add my google account to the play store, all my apps have the paid for attributes turned on. My game shows all the progress that has been saved. I wonder how sandboxed the google play store is if my widget is fully enabled and all the paid for and saved progress is now available on all my apps.
Secondly, when i got into accounts on my graphene phone and remove the google account, when i load play store it asks for me to sign in as i am not currently signed in, as expected, BUT the paid for attributes and game progress are retained.
I have tested this with a friends graphene phone, same outcome. I can have play store apps fully enabled and functional without retaining the google account on my graphene phone.
Is this known, expected, normal, or some crazy discovery?
