What makes Privnote different from sending a regular email or instant message?

• You get a link to the note, and once that link is clicked the note is destroyed so it can only be seen once. If someone intercepts the link and sees the note before the person who's intended to read it, that person will known that the note has been eavesdropped, and can tell you about it.
• If you want to be notified when your note gets read you can do it by checking the notify box located below then note. Neither email nor instant messaging provides a reliable way to know if, let alone when, your messages are read.
• If you send a note and suddenly regret having done so, you can click the link yourself which will destroy the note and prevent the receiver to read it.

Sending links in emails is as easy as writing the note in the email itself, so why not add a little extra privacy at zero cost?. Besides, everybody knows how to click on a link so you won't have to explain anything new in your email.
