I tried not to make this post lol and tried to do my own research but I’m ready to admit defeat: What is the best app to store contacts so that they are backed up in the cloud? I found DAVx⁵, OpenContacts, and others but I have no idea which one is best to use. I need one that is focused on privacy and also encrypts cloud storage.
Honestly I didn’t think about the fact that he wanted to backup tutanota contacts, but phone contacts, for this reason I also recommended sms import / export that allows you to make a periodic backup of phone contacts as well as sms
Exactly what I do (even if DAVx⁵ or Nextcloud, I don’t which of them, currently mess up some of my contacts for instance by “automaticaly filling contacts initials”!).
