My Android app gives users a free monthly quota for the service provided. Users are required to sign in with Google to keep track of the quota.
Now the documentation for Google Sign-In states here
It is highly recommended that you provide users that signed in with Google the ability to disconnect their Google account from your app. If the user deletes their account, you must delete the information that your app obtained from the Google APIs.
and here even:
Applications are required to provide users that are signed in with Google the ability ...
But if I delete the record with the user's quota usage, a user could always simply disconnect his account and sign in again to get new free quotas.
Would it be against Google's terms if I state in the privacy policy and terms of service that a record about the quota-usage is kept even if the account is disconnected?
Does someone have another idea?
