For the passwords, keys and door codes you send over Slack, Teams or email. One link that deletes itself the moment it is read — and link previews can't burn it, because only the recipient's click on Reveal counts as the read.
Warning · this is an experiment This app was entirely ideated, tested, built and deployed by a software factory created by Landon Gray. Please don't put any real sensitive information in the box below — no passwords, addresses or other personal details.
Opening the link shows a Reveal button, nothing more. The first person to click Reveal reads the note, and that read is the delete. Unread notes burn after 24 hours.
