Understand exactly what happens to your messages from creation to destruction
Your message is encrypted with AES-256-GCM before leaving your device. The encryption key never touches the server—it lives only in the URL fragment you share.
The relay server only sees encrypted blobs. It cannot decrypt your messages because it doesn't have the key. No plaintext, no identities, no metadata is ever stored.
The recipient's browser uses the shared key from the URL to decrypt the message. Decryption happens entirely client-side—the server never sees the plaintext.
When you close the tab or the timer expires, the room is destroyed. No history is saved—everything burns. Even if someone has the link, they can't recover past messages.
The encryption key is never logged, and the relay forgets the room ever existed.
