No account, phone number or e-mail is needed. The audio is encrypted with WebRTC (DTLS-SRTP) and travels phone to phone; a relay is used only when no direct path exists and cannot decrypt anything.

As the default SMS app it handles SMS and MMS, including groups, with quick reply. No ads, no analytics and no tracking. Available in 11 languages.
