Encrypt your content before it leaves your device. Send it anywhere. It stays locked - no matter where it lands.
The channel is locked. But the moment your message lands - it's readable. One wrong contact. One unlocked phone. Everything exposed.
⚠ Encryption ends on arrivalCipherBrick encrypts the content itself. The channel doesn't matter. The destination doesn't matter. Only the right key opens it.
