Channels
One Channel for one team
Keep each project separate. Invite only the people who need access, then let the Channel expire or renew it when the work continues.
See how Channels work
End-to-end encrypted
Messages and supported files are encrypted on your device.
Routed through Tor
Messaging traffic reaches M2 through a v3 Onion Service.
Temporary server storage
Encrypted copies are removed after delivery or within 48 hours.
Messaging and files
Messages, voice notes, and files in one place
Share what the team needs inside the Channel. Voice messages and received files stay easy to find without mixing the work into personal accounts.

Built to reveal less
M2 does not require a global user profile. Messages are encrypted on the device, messaging is routed through Tor, and encrypted server copies are kept only long enough for delivery.
