An encrypted messaging app uses cryptography to make your conversations unreadable to anyone except the intended recipient — not the service provider, not your ISP, not a network attacker. NoChat implements end-to-end encryption so messages are encrypted on your device before they're ever sent.

Yes. Messages are encrypted with AES-256-GCM using a session key derived from ECDH key exchange, and keys are generated client-side. The NoChat server only ever sees ciphertext. You can verify this in the open-source code at github.com/kindlyrobotics/nochat.

AES-256-GCM for symmetric message encryption, HKDF-SHA256 for key derivation, P-256 ECDH for classical key exchange today, and ML-KEM (Kyber-1024) for post-quantum key encapsulation — the NIST standard chosen to resist quantum attackers.

Signal and WhatsApp still require a phone number at signup, which links your identity to your account. NoChat supports fully anonymous signup with no phone number, and we ship post-quantum encryption that neither Signal nor WhatsApp offers today.

No. Your private keys never leave your device, and the server only stores encrypted payloads. Even under legal order, we could only produce opaque ciphertext — we have nothing to decrypt it with.

Yes. The entire client and server are open source at github.com/kindlyrobotics/nochat so anyone can audit the cryptography and verify that encryption claims match the code.

No. You can create an anonymous session in one click and start an encrypted meeting immediately. No email, no phone number, no identity required.

Yes. Video and audio calls use encrypted peer-to-peer WebRTC, so media never passes through our infrastructure. Voice, video, and chat are all protected under the same end-to-end encryption model.
