"Here's a great way to send a confidential note to someone. For example, if
you've emailed someone an encrypted document and you need to inform them of
the password for the file. Head to this free website in your web browser.
Type the confidential message, then press the Send button. You'll be given a
unique URL to your message, which you can now email to the recipient. When
they click on that URL, they get to read the message you entered. So now
you're probably wondering what makes Burn Note any more secure than
traditional email. Firstly, the unique URL will only work once, after which
the note gets deleted from the system. Secondly, if the recipient leaves
their browser window open with the note visible, it'll self-destruct after 3
minutes. And re-visiting the unique URL won't bring it back."
