Jot a note, send the link
Write something down, hand the link to whoever needs it, and it clears itself the moment they open it — nothing left sitting in an inbox or a chat log afterward.
Everything is encrypted on your own device before it's sent anywhere, so this site never stores anything readable. Bookmarking or history-saving this page only shows a plain, unremarkable page — it never shows what a link contained or whether it was ever opened.
