Notes that will self-destruct after being read

You can send confidential (or other) notes that would destroy themselves after being read just once.
1. Privnote is the solution
2. Write a note and click 'Create' to obtain a link.
3. Copy this link and send it to the person you want it to read, by pasting it into an email or in an IM.
4. The note will not be available to be read for a second time once the link is clicked upon.
5. If you want, Privnote can notify you when your note get read!
6. After sending the note if you regret sending it, you can destroy it before the person reads it, by opening the link yourself.
