  1. 01Your browser encrypts the secret — plaintext never leaves this tab.
  2. 02The server receives only ciphertext it cannot read.
  3. 03Opening requires both the private link and the password.
  4. 04A successful reveal atomically deletes the stored copy.
  5. 05No accounts, no analytics, no secret history.

Honest footnote: no tool can erase what recipient devices, screenshots, or clipboard managers do afterward. What we control — our server — never sees plaintext, and forgets the ciphertext the moment it is read.
