This might be a dumb question so apologies in advance. I’m looking into degoogled phones but haven’t taken the plunge yet. If I logged in and used the aurora store to get apps I paid for in the past, will that ''regoogle" my device and allow google to track me again through signing in and using those apps?
Check out GrapheneOS. They sandbox google play services so you have a lot more control over what is sent to google. Might be a good middle ground.
Those purchases will be lost if you want to degoogle. Just went through this some time ago and actually it was a good opportunity to think about which one I’m really using. The ones I really like and there was an opportunity to buy them outside of the Google ecosystem, I rebought (for example Tasker). For all others, I found good replacements.
