Just got my Graphene phone working. I am trying to get off google as well. I am looking for suggestions about how to replicate contact syncing without using google. I have a home lab and have been looking at nextcloud as the backend and using something like DavX5 to sync to graphene. I am looking for a way to keep my contacts synced to a single account. I would also like the ability to delete the account from graphene and have the contacts associated deleted as well. i work with some activists and journalists and dont want to keep their information in my phone when I have to cross international borders just as a precaution.
any suggestions welcome.
