About

Qwertion is a minimal private messaging application designed for two people. It has no accounts, no contact lists and no public rooms. You create a chat with a name and a code, share them privately, and the conversation stays between you and the other person.

Chats. Each chat has a validity you choose, from 1 hour to 7 days. Once the second person joins, nobody else can enter.
End-to-end encryption. Messages are encrypted on your device with AES-GCM, using a key agreed through ECDH P-256. The server relays ciphertext it cannot read.
Peer-to-peer files. Files go directly between devices over an encrypted WebRTC channel. The server does not keep them.
Local storage. Messages exist only in this tab's memory and are gone when you close it. Your private key stays in this browser until you leave the room.
Online status. Presence reflects an active connection. If your connection drops, you will see Reconnecting rather than Online.

Qwertion has not been independently audited. The server can still see IP addresses, connection times and room activity. See SECURITY.md for the full model.
