How to send a secret message that nobody else can read
Write the message in the box above. Your browser encrypts it with AES-GCM-256 and keeps the key in the link after the #, so LinkPilot stores ciphertext it cannot open. Send the link by text, email or chat. The recipient opens it in any browser, presses reveal, and reads the message. The stored copy is destroyed as part of that reveal, and the link shows a burned page to anyone who tries it afterwards.
No app is needed on either side, and the recipient does not need an account.
