DESIGNED FOR PRIVACY
LESS IDENTITY.
MORE CONTROL.

No unnecessary contact exchange
Connect through the conversation instead of automatically exposing your personal number.

Direct invitation
QR codes, private links and chat keys give you deliberate ways to establish a connection.
03
Protected communication
Use encryption and secure transport for the data the current implementation protects.
04

FAQ
STRAIGHT ANSWERS.
TECHNICAL WHEN IT MATTERS.
Can I use Chat256 without a phone number?
Yes. The core Chat256 chat experience is designed to start without requiring your personal phone number.
Do I need a traditional account?
No traditional account is required for the core chat workflow.
How can someone join my chat?
Chat256 supports direct invitation methods including QR code, private link and chat key, subject to the current application flow.
What does AES-256-GCM provide?
AES-256-GCM is an authenticated encryption mode. It provides confidentiality and integrity for data encrypted with the appropriate key and nonce handling. The implementation details and key lifecycle determine the security of the complete system.
Is Chat256 anonymous or untraceable?
Chat256 is designed to reduce unnecessary identity exposure. That is different from claiming that a user, device, IP address or network activity is untraceable. Privacy protections depend on the application, device, network and deployment environment.
Does HTTPS/WSS matter if application data is encrypted?
Yes. Application-level encryption and TLS solve different problems. TLS provides encrypted transport, server authentication and protection against network tampering; application encryption can provide an additional confidentiality layer for supported data.
