Link

Secure communication for your own people only

A messenger for Falcon OS. No phone numbers, accounts or email. Messages, files and calls are seen only by you and your contact โ€” the server merely relays ciphertext and keeps nothing after delivery.

๐Ÿ”’

End-to-end encryption

Messages and calls are encrypted between devices. Neither we, nor the servers, nor the carrier hold any keys.

๐Ÿ†”

No numbers or accounts

No phone number, email or login. Your identity is tied to nothing an operator could be asked for.

๐Ÿค

Trusted devices only

Works only between Falcon OS devices. When adding a contact, the phones verify each other's hardware authenticity.

๐Ÿ›ฐ๏ธ

Resistant to blocking

Traffic goes through our own protected gateways. If one becomes unreachable, the device moves to another.

โณ

Disappearing messages

By mutual agreement, conversations erase themselves โ€” from 30 seconds to a month.

๐Ÿ“ž

Voice and video

Encrypted calls over the same protected channel, with no third-party services.

How it works

Link ships with Falcon OS. On first launch the device activates โ€” it proves its authenticity and receives a personal protected channel. After that you add contacts in person, by QR when you meet, and talk directly. History lives only on the phones themselves: losing the device means losing the history; there is no recovery by number or email, by design.
