Share sensitive info safely: one-time notes (deleted after read), secure links with password/click limits, and a 100% in-browser EXIF cleaner.



Share a confidential note via a web link that will self-destruct after it is read by your intended recipient

BurnPony seals a note on your phone with AES-256-GCM, hands you one link, and steps out of the way. The recipient opens it in any browser — no app, no account — and after the last allowed view the note is gone. The server in the middle only ever holds ciphertext.
