I sync it using my pCloud folder. In case I'm away and I need access to them, I also have a cron job that copies the most recent version to a webserver I have, under a directory I only know of, protected by a password. My .kbdx files also need a credentials file that can be generated programatically. Secure enough for me.

As a European (but who lived for 10 years in Montreal, that's why I have an account here) I applaud any initiative to move digital infrastructure away from the US. Good luck.
