Secret Share

Write something, encrypt it in your browser, and share a link. The server only ever stores ciphertext — the decryption key travels in the link itself and is never sent to it.

Access policiesEach policy below produces its own separate share link, all pointing at the same encrypted message.
Unlimited views
Up to 3600s (1 hour). Once opened, the message clears itself from the screen after this many seconds — even if the tab is left open. Leave blank to only clear on refresh.
The link (including the part after #) is the secret. Anyone who has it can view the content per its policy. There is no way to recover it if you lose it — the key is never stored server-side.
