We share a lot of things in our daily lives — whether through social networks, email or IM. Sharing is natural. The problem arises when we share sensitive information with others.
We easily send emails with usernames, passwords or other important information to our friends, co-workers and clients without thinking. Its simple and quick to do and we tend to trust those we share this information with.
However, there are always digital traces left behind that we never think about. You just emailed your wife the pin number to your ATM account. Was the emailed deleted or is it still in her inbox? Or how about the username and password to a new site you’ve just built for a client that was sent to them. Do they still have it sitting in their inbox?
This is how the site was born. Provide the ability to send private information to someone else and know that once they’ve read it, its deleted.
