@nprofile1q... I’ve been using Joplin happily for about three years. I only lost data once at the beginning to a bad WebDAV sync. I like th simplicity and the markdown support. I don’t love the “proprietary” backup format.
I’m currently experimenting with QOwnNotes and SyncThing. I love QOwnNotes on desktop and Markor on phone. Problem is zero iOS support if that’s what you need.
