Since getting GOS I've always had to use Google contacts as my cloud sync to keep a backup. Not great for privacy at all.
I tried tuta but that didn't work great for me, plus they delete yr account if you don't login after a certain amount of time which was too risky for me
Finally got something private e2ee with free cloud sync.
Disroot cloud service gives you hosted nextcloud facilities including e2ee contacts sync.
Setup is a breeze including installation of the required DAVx to sync.
Finally have a private contacts cloud sync without hosting my own server and can degoogle contacts now.
Thought this might be useful to others that had the same problem.
Thx
