IMHO if you only care about Google sucking your data and not other privacy/security, the most important question isn’t between OSes as much as it’s between:
-
No Google apps (GAPPS); honestly good ol’ LineageOS is just fine. If you don’t install Google spyware you don’t have Google spyware, just the connectivity check and dns. Which you can probably change. Major con, many applications installed from Play store (through Aurora store, apk, whatever) and practically all notifications you’d receive from them stop working.
-
MicroG; open source GAPPS replacement that tries to send as little data as possible to Google, while keeping Play store apps & push notifications working. /e/, iodé, Lineage for MicroG, Lineage but add microG manually during installation, formerly CalyxOS…
-
Add GAPPS but try to handicap it somehow (incl. GrapheneOS work profile isolation); I don’t remember if it’s eg. possible to block them from accessing the Internet on non-GrapheneOS phones, by app permissions or eg. NetGuard?
If we’re taking into account other privacy and security, then GrapheneOS by a mile.





Is it only Graphene? I vaguely recall having had it on DivestOS (RIP), which was a Lineage fork.Edit: Any app, duh, yes, silly me. Don’t remember if it was possible for all of them.
