Then you move your privacy concerns to your ISP.

Kubuntu comes with Apt, and from time to time I use Nala too.
Bitwarden here. Was also a LastPass user. Switched when I retired so I did not have to worry about still keeping any old accounts from work. P.s. Also I like that I can have Bitwarden sync on my phone and my laptop.
Ah, That's why I asked - It has been a long time since I used Joplin, and did not use any of those features when I did (um, I may have had Joplin on my phone tho, but I don't remmeber if I synced between phone and laptop Joplin)
What about Zim? I have been using Zim for a few months. I had used Joplin in the past, and I don't remember any issues but for some reason the most recent time I reloaded/distrohopped I installed Zim instead. The one feature I like about Zim is tables in my notes.
But an ISP can get all that sweet meta-data from your packets - where they are going, and maybe from your DNS queries.
