The anonymous messaging app that forgets you on purpose.

Your phone number is the single most linkable identifier you own, tied to your real name, your address, your billing information, and probably your other social accounts. The instant a messenger collects it, your supposedly anonymous account is welded to your offline identity. That's why private messaging with no phone number isn't a feature in NoChat. It's the foundation.

Signing up to NoChat requires no SIM card, no SMS verification code, and no carrier interaction whatsoever. Your identity is a cryptographic key pair that lives on your device. People reach you by username or by a key fingerprint, neither of which depend on any phone carrier knowing you exist.

Anonymity collapses the moment a server can correlate sessions back to a real identity. NoChat is built as a zero knowledge messaging system: your private keys are generated and stored on your device, the server only handles encrypted ciphertext, and there is no escrow or recovery mechanism that could be used to retroactively de-anonymize you.

We don't attach IP addresses to user records, we don't fingerprint devices, and we don't build social graphs from contact uploads. There is nothing in the database that a hostile actor, or a subpoena, could use to convert an anonymous user into a named one.

If your anonymous messaging app uses only classical encryption, today's anonymous conversation becomes tomorrow's deanonymized record. A quantum adversary with stored ciphertext can retroactively unseal both the content and any timing or routing patterns. For people who rely on anonymity (journalists, activists, abuse survivors), that's not an abstract concern.

NoChat closes the window by combining anonymous signup with post-quantum key exchange for direct messages using ML-KEM (Kyber-1024). Your anonymous DM today still looks like an anonymous conversation in 2040, even to an adversary who recorded every byte.
