UsChat is a peer-to-peer encrypted messenger for iOS. Each account generates its own key pair on-device — our servers carry the envelope, never the letter.
End-to-end encryption isn't a feature we bolted on. It's the architecture.
When you create an account, UsChat generates a unique key pair locally. The private key never leaves your phone — not even to us.
Every message, photo, and file is sealed with the recipient's public key on your device. By the time it hits the network, it's already unreadable.
Decryption happens on their device, with their private key. Our servers route the envelope. They cannot — and will not — read the letter inside.
