Photon
A messenger with nothing in the middle.
No account. No phone number. No password. Your device is your key. Messages, voice and files go straight from it to your friend's, scrambled so only the two of you can read them. Nobody in between holds a copy, because there is nobody in between.
Add your other phone or computer and they keep everything together, so losing one loses nothing. Free, open, and running between real people since July 2026.
Two devices. One line. Ends: 2.
