PRIVATE BROWSER TOOL
Send a one-open secret note
Write one message, choose an expiry, and share the secret link directly. The first explicit reveal consumes the note, even if decryption fails.
Protected against ordinary chat-app link previewers: loading this page does not consume the note. A holder of the full link can still reveal it.
What one-open means
The server deletes the live ciphertext during its first authorized retrieval. Opening a link with the wrong key can consume the note without showing its contents. Someone who reads it can still copy or photograph it.
Who can open it?
Anyone with the complete link can open it once before expiry. Keep the link private. Vanish has not had an independent security audit, and infrastructure backups or logs may persist beyond live deletion.
Questions about this tool
Does a link preview burn the note?
Loading the page does not consume it. A holder of the complete link must explicitly choose Decrypt & Reveal.
Can I open a one-open note twice?
The first authorized retrieval consumes the live ciphertext, even if decryption fails. Recipient copies, provider logs and backups may remain.
