Private messaging. No phone number. None.
They're watching. Every message.
Hey, can you send me the account details?

Sure, the password is Summer2024!

Got it. What about the PIN?
10:44 AM
It's 4729. Don't share this with anyone.

Without encryption, every keystroke is exposed.
Private messaging that doesn't wantyour phone number
Your phone number is the single most linkable piece of identity you own. We don't ask for it — ever.
Never Asks for a Number
Signup doesn't have a phone number field. There's no SMS step, no verification code, no carrier involved.
Identity as a Key Pair
Your account is a cryptographic key pair held on your device. Contacts find you by key fingerprint or username, not phone number.
Immune to SIM Swap
Since there's no phone number attached, SIM swap attacks have nothing to hijack. Your account can't be stolen by trading phones.
Encrypted End to End
Private means the content is actually private. Every message is end-to-end encrypted, and direct messages add post-quantum key exchange on top.
Built on auditable, standards-based cryptography. How we secure it
Your carrier can't leak
what they never had
Carrier databases are one of the biggest sources of identity leaks on the internet. When NoChat never stores your phone number in the first place, a carrier breach can't touch your private messaging.

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.
