Resources to help you trust — and verify — Blink.
Browse our whitepapers, threat model, honest roadmap, and support resources. Blink is private by design and fast by default.
Security whitepaper
Learn how Blink encrypts messages and media on your device with authenticated encryption, keeps its keys in your phone's secure hardware, and rotates keys every seven days for forward secrecy.
Threat model
We spell out what we defend against and what we don't: servers that only ever hold ciphertext, encryption keys that stay on your device, a duress wipe, and screen protection.
Honest roadmap
See what's live today and what's coming soon, including end-to-end encrypted (E2EE) calls and additional data-residency regions.
Help Centre
