Sending all the voice messages I get to some server? Uhm, no.

Great idea in theory, though.

A bunch of marketing blah blah, I wonder what they’re up to.

Matrix is not the right protocol for staying anonymous. There’s way too much unprotected metadata.

You might be able to mitigate that somewhat by using an instance that is accessible via TOR and being careful who you communicate with, depending on threat models and so on.

But if you want to communicate anonymously and not leak meta data… Probably not what you are looking for.

• user names cannot be changed
• never delete your database, have backups, all the state is in there, if you lose your DB, you essentially have to set up a new server: Your server will say you are not in a room while others say you are, so you cannot join. Always keep your DB backed up.

Pretty much the only one.

Though there’s also Neochat fron the KDE F-Droid Repo.
