[Tox](
https://tox.chat) is a decentralized chat protocol with end-to-end encryption. I've been hearing a lot about Signal's "fall from grace" again now all of a sudden (the news was old, so that's a mystery to me). I've never used Signal, because I don't use an Android phone, but I have never been comfortable with a central server. Tox is decentralized and checks the boxes I like.
You can find tox clients [here](

I don't have many viewers, so I've no problem putting that up and can edit it out later if it becomes a problem.
