Cryptans -is a private messaging application built on one principle: no one except you and the person you're talking to can ever read your conversation. Not the server. Not the company. Not anyone in between How it works? -Every room is created with a 6-character invite code. That code is never sent over the internet — you share it in person, by phone, or through any channel you choose. This means there is no moment where the code travels through our infrastructure. Once two people are connected, the encryption session begins automatically. THE ENCRYPTION -Every message is encrypted on your device before it leaves. The server receives an unreadable blob of bytes and forwards it to the other person. The server cannot decrypt it. We cannot decrypt it. WHY INVITE CODES MATTERS? -Most messaging apps exchange encryption keys over the internet, which creates a window where a sophisticated attacker could intercept. Cryptans removes that window entirely. The code is the key handshake. It happens offline. There is no attack surface. WHAT THE SERVER KNOWS? -The server stores a SHA-256 hash of your room code. never the code itself. -It sees that two connections joined a room. It sees encrypted blobs pass between them. It cannot read them. -Your IP address is immediately hashed with a rotating daily salt and discarded. No plaintext IP ever touches storage or logs. its 100% secure if people dont make mistakes #Avazaky < 3
