Privacy is a right, not a feature.

We started Blink with a simple conviction: the people you talk to, the files you keep, and the moments you share should be yours alone. Not the server's. Not ours. So we built encryption in from the first line of code — not as a setting you have to find, but as the default that holds everywhere.

Every message and every file is sealed with AES-256-GCM before it leaves your device, using keys derived through ECDH on the P-256 curve and HKDF-SHA256. Our servers store only ciphertext. Your conversations live in the cloud so you can restore on a new device, while your keys never leave your hands — your device holds only derived keys and an encrypted vault. That's the whole point: powerful, fast, and provably unable to read you.

Blink is the polish of a modern team messenger with the trust posture of a privacy-first one — secure messaging, groups and admin channels, a Secure Locker for files, an anti-keylogger keyboard, remote device wipe, and a reverse-PIN duress wipe for the moments that matter most.
