For example, Let's say I have 2 play store accounts signed in on android: > [email protected] > > [email protected] Event 1: I sign into the app using alice@g, and then make a payment to the app using the Google Play Payment Method (GPPM) associated with alice@g, and which is assigned order: GPA.111... Event 2: I then delete the app's data in settings and remove then reinstall it on the same device, but sign into it using bob@g. I then make an app payment using the GPPM associated with alice@g (since it is available and already on the phone), which is assigned order: GPA.222... My question is, for Event 2, is there anyway for the App-admin to associate bob@g's login with the alice@g login (for example, does the GPPM send the app admin an e-mail address such as alice@g or an id, such as gppm-id-alice, or gppm-randomId-associated-with-alice) or is each payment with GPPM fully anonymous?
