Do you mean encryption decryption happens locally of each individual note and only the encrypted string is stored online?
How would you trust to sync the decryption keys across devices?
Yes. Joplin supports this (although sync gets slow when the number of notes is large). Syncing the encryption keys is your responsibility. I transfer them over the wire to devices I use without sharing them with a third party service.

Now with Joplin Server it’s getting better (compared to WebDAV), in terms of syncing speed
