This little and useful service allows you to create safe message that will be self destruct right after accessing it. So, if you need safely send someone your secret information, then instead of passing it directly by email or skype, you may send only a link generated especially for your message. Being visited, the message is permanently deleted and the link is no valid anymore. For additional security, the service allows to specify a password.
Being created, the information is safely encoded. As mentioned above, visited or expired messages are permanently removed from database and no one have ability to access them again.
Of course, it's very hard to trust any third-party service such sensitive information as logins and passwords, and you definitely should not. But instead, you may want to separate your message and send it by segments via independend sources. In this case, this service may become very helpful.
