Yeah I’ve tried that with my webdav mount coz its the obvious thing to do.

Problem is local notes are exposed to other apps and unencrypted.

Apps like neutrinote can protect notes in their app sandbox and create a backup mirror in location of choice e.g. a webdav Mount that happens to be behind mtls.

Syncthing does not offer mtls.

Thanks for the info. Will look in to that approach too.

Mtls requires that the android client device has a certificate installed that matches the one installed on the server in order to access it.

Not Foss. Kinda of a privacy nightmare as you need to verify your identity and location with actual documents but as already said its not google and is a solid option if you are degoogled.
