Using GrapheneOS, my main profile has a handful of apps from PlayStore(Aurora): 1password, ProtonVPN, ProtonMail, etc.
I think I read somewhere that, for an app to appear in PlayStore, it must be compiled with linked libraries that implement check-ins with Google infrastructure… or something like that.
Obviously I’d expect apps like 1password and Proton to be “less evil,” but am curious whether everything from playstore leaks telemetry, or if it’s just “up to the developer”.
(in my case, I don’t have Google services or apps in the main profile at all)
Aurora should actually say in the description of the installation/update screen if the app requires google play services or any telemetry at all (or for that matter, google sign in).
