## Description

khazan — offline chat for workers and teams in places with no network coverage: tanks, tunnels, construction sites, warehouses, basements and remote areas.<br><br>HOW IT WORKS<br>Open the app and it automatically finds nearby coworkers over Bluetooth within seconds — no internet, no cellular network, no account, no phone number. Messages hop from phone to phone (mesh networking) to cover areas far beyond normal Bluetooth range.<br><br>WHAT YOU CAN SEND<br>- Text messages with delivery and read receipts<br>- Photos from camera or gallery<br>- Voice notes and push-to-talk walkie-talkie<br>- Your location — only when you choose to share it<br>- An urgent ring alert to a specific coworker<br><br>SOS DISTRESS CALL<br>An emergency button fires a loud siren, camera-flash strobe and vibration on every nearby device, repeating automatically — built to rescue a worker trapped in a tank or tunnel.<br><br>REACH FURTHER WITH INTERNET<br>When any internet connection is available, an additionally-encrypted copy of your messages is relayed through public relay servers to reach a distant coworker — and a single connected phone can act as a gateway for the whole group. One tap turns this off.<br><br>REAL PRIVACY<br>- Full end-to-end encryption (X25519 + AES-256-GCM)<br>- No accounts, no sign-up, no developer servers<br>- No ads, no tracking<br>- Conversations stored only on your phone<br>- QR identity card to add a distant coworker safely<br><br>EXTRA TOOLS<br>Smart call log, fast contact search and coworker-to-contact linking — all on-device.<br><br>Perfect for maintenance crews, construction, factories, mines, ships, events and off-grid trips — anywhere the network disappears but communication must not.
