About Zero Note

Zero Note is a utility for sending one-time secrets and confidential notes. You write a note and share it as a private encrypted link, and it destroys itself according to rules you set: after a number of views, after a time limit, or both. A whitelist can limit access by location or country, an email notification tells you when the recipient opens it, and an audit trail records when the note was first and last seen.

A keyboard extension lets you share sensitive messages from inside other apps, encrypting a vault note or clipboard text into a self-destructing link. The app is available in seven languages, requires iOS 18 or later and is free to download with in-app purchases. A sale on the app is mentioned in the listing.
