Phillybread00 Just installed Graphene OS, for the play store sandboxed mode, its still making me enter a Google account.
On GrapheneOS the sandboxed Play store is exactly Google's Play Store app, without modifications. It is "sandboxed" in the sense that it runs under the normal Android app rules instead of having elevated privileges. "Sandboxed Google Play" does not mean "Google Play with an added magic privacy shield that causes Google to never require you to provide information".
Like a regular Android app, Play can't read your IMEI or your phone number or your location, unless you authorize it. But in order to use some functions of the Play ecosystem, including some app features, you will need to provide some information to Google.
Phillybread00 How safe is this? I don't want Google anything.
If you don't want Google to know anything about you, it is best not to install Google Play (and, on other Android variants, best not to install microG, which also installs some Google code and also leaks some information to Google).
Most open-source apps are not designed to leak information about you to Google (and many are not designed to harvest information about you at all).
