This app seems similar to logseq

But logseq doesn’t have the same limitations listed here.

Logseq does let you import markdown (uses markdown as its notes format by default also supports .org) and export to PDF and HTML.

As for syncing I just use syncthing to sync all my Notes and that works fine.

Probably wouldent work on modern cell networks.

You realize anyone can just host their own server right?

Just because nobody wants to hear what you want to say doesn’t mean it’s censorship don’t like your server’s rules find another one or host your own.
