I am surprised that Google spends so much time tackling custom ROMs via it’s Play Integrity API. If only they paid that much attention to say, curating the Play Store more, it had be much better for everyone
Two credit union apps work fine, venmo and paypal work fine. YMMV with other financial institutions but it’s not been a problem for me so far.
To answer your last question, there’s way too many differences for a lemmy comment, so I suggest reading their features page for a broad overview: https://grapheneos.org/features
One feature that’s closest yo your question, though:
Google Play receives absolutely no special access or privileges on GrapheneOS as opposed to bypassing the app sandbox and receiving a massive amount of highly privileged access.
I read it and I think I understand why people are using it, but just to clarify your Google play example: you still can’t use it without being signed into Google account, right? Is your concern what the app does while it’s not running? Because it feels like they’ll still collect the same amount of info once your sign in to install the apps.
Do you you try to use F-droid for most things?
It’s unfortunately really not that simple. But for a short answer, I use Aurora Store for anything I can’t get from F-Droid., and even tho I have the Google Play Store installed (as some apps require it for stuff like notifications or location) I’m not ever signed into it and I don’t use it to install or update apps
