Create a private room, share one link, talk, then destroy it. Messages are encrypted in your browser and never stored anywhere.

How the security works
  • Your browser generates a random encryption key and puts it after the # in the room link. Browsers never send that part to any server.
  • Every message is encrypted with AES-256-GCM before it leaves your device. The server only relays scrambled data it cannot read.
  • In password rooms the key is derived from the link and the password, so someone who only gets the link cannot decrypt anything, even if they bypass the server. The server stores a separate check value that does not reveal the key.
  • File attachments get the same treatment. A file is encrypted on your device with the room key before it leaves, sent to the other members in pieces, and decrypted only in their browsers. The server relays the pieces and never stores a file.
  • Every message and file carries a timer chosen by its sender, one hour unless changed, from one minute up to never. When it runs out, every member's browser deletes it. The timer travels inside the encrypted data, so the server never sees it.
  • The server keeps rooms in memory only. Destroying a room erases it completely, and any room with no activity for two days is destroyed automatically.
  • Timers and deletion are carried out by each member's browser. A file someone has already downloaded to their computer is outside the room's control.
  • Creating a room may ask for a quick human check from Cloudflare to keep bots out. It runs on this page only. It is never loaded on the password page or inside a room.
  • Nothing can stop a participant from photographing their screen. Only share what you would say out loud to the same people.

Set the room password

Members will need the invite link and this password. It becomes part of the encryption key and is never sent to the server.

    Keyboard: Enter sends, Shift+Enter adds a line, Escape twice wipes this device and leaves the room. Paste an image from the clipboard to send it. Click a picture to enlarge it, and press Escape to close it.

    Honest limits: a website cannot detect macOS, iPhone, or Android screenshots, or a camera pointed at the screen. These options raise the effort, they do not make capture impossible.
