> You need that sync for backup purposes.

Backup is a simple one way sync, but like you said, it is needed. It could still be private, if backup to another of your devices is made when your phone connects to your home WiFi.

>>zigzag+(OP)
You can (in principle) back of over the cloud and still have everything private. Encryption and open source software can handle that. (You want the software to be open source, so you can check that it's really end-to-end encrypted without a backdoor.)

Of course, that scenario would only become the norm, if there's mainstream demand for that. By and large, there ain't.
