About the startup
I'm building PTT Chat — a privacy-first voice messenger that works in the browser. Privacy features already implemented: End-to-end encryption for private messages (E2EE) No phone number required — you can join as a guest No ads, no data selling What I'm considering adding: Self-hosting option Open-source the client Ephemeral messages The project is funded entirely by donations — no investors, no hidden agenda.
