What do you think of SimplexChat? It does not require a phone number or account setup and you share single use links to set up a chat so there’s no identifiers that can be traced back to you. I’ve been using it with my friends for years now. It has some reliability issues but you can even host your own server if you want full control.

Go use SimplexChat at least, it only uses single use identifiers and you don’t need an account !
