I have switched everything to privacy alternatives is it safe to delete my Google account or is it needed for some android features also if I delete my account does Google delete all my data if not, can I request the deletion of my data under the GDPR
Google Account deletion in theory should delete all data stored in Google, but that theory rests on Google following up on what basically amounts to a pinky promise. As long as you don’t have anything important stored anywhere, like in your Google Drive/Photos, etc…, it should be fine.
