The encrypted messaging app with no phone number.
They're watching. Every message.
Hey, can you send me the account details?

Sure, the password is Summer2024!
10:43 AM
Got it. What about the PIN?
10:44 AM
It's 4729. Don't share this with anyone.

Without encryption, every keystroke is exposed.
The secure messaging app where privacy is a right, not a feature
NoChat is an encrypted messaging app built from the ground up for anonymous messaging, zero knowledge storage, and post-quantum encryption. Here's what that actually means.
Post-Quantum Encryption Messaging
Every message is protected by post-quantum end-to-end encryption (ML-KEM / Kyber-1024). Your conversations stay private even against future quantum attackers.
Private Messaging, No Phone Number
A phone-number-free chat app. No SIM, no SMS, no identity required. Start anonymous messaging in seconds without surrendering personal information.
Zero Knowledge Messaging
A zero knowledge architecture: we store encrypted blobs, never your keys. Your private keys never leave your device, so we literally cannot read your messages.
Encrypted Video & Audio Calls
Crystal-clear peer-to-peer video and audio, fully end-to-end encrypted. No media passes through our servers — it's just you and the other side.

A messaging app built
for the quantum era
Quantum computers will break today's encryption. Every message you send now could be stored and decrypted later. NoChat is among the first messengers shipping post-quantum key exchange for direct messages — protecting you today against tomorrow's threat.

Harvest Now, Decrypt Later
Why this matters today, not tomorrow
Nation states are already storing encrypted communications. When quantum computers arrive, they'll decrypt years of captured data instantly.
Most mainstream messengers — including WhatsApp and Telegram — still don't offer post-quantum messaging. NoChat ships post-quantum key exchange for your direct messages today.

Join the quiet ones
Join a community that values privacy over convenience.
No phone number, no tracking ID
Sign up anonymously. There's no number to link your conversations back to you.
Encrypted on your device
Messages are sealed with AES-256-GCM before they leave your device. The server only ever sees ciphertext.
Read the code, don't trust us
The entire client and server are open source. Verify every claim on GitHub instead of taking our word for it.
