Open Source Alternatives to Privnote

A secure note sharing service that allows users to send notes that self-destruct after being read. The tool encrypts notes directly in the browser and generates a unique link for distribution via email or instant messaging. Users can set custom passwords for additional encryption, define specific expiration dates ranging from one hour to 30 days, and opt for email notifications to be alerted when a note is destroyed. It is designed for individuals who need to share sensitive information that should not persist once the recipient has viewed the content. The service is accessed via a web browser and requires JavaScript to function correctly. It provides options to disable confirmation prompts before the destruction of a note and allows for optional reference names to be assigned to each entry.
