What is this site?
This site allows you to store information, such as passwords, in a "locked box" that only allows access after a waiting period. You can discover how it works by trying it.
Why do you require email?
Well, we have to authenticate you somehow. And email is easy. We will not sell your email to a third party nor send you mail except the mail(s) that you need to access your lockbox account.
Why do boxes self-destruct?
Boxes self-destruct because it is impossible to hold information forever, and we do not want users to think we will. Currently, the longest lived box is one year.
