Wickr (pronounced "wicker") is a proprietary mobile app for Android and iPhone which is designed to help users send messages, including photos and other attachments, which are automatically deleted after a specified period of time. The recipient needs to be running compatible software to read the messages.
The "self-destruct" part of the software is designed to use a "Secure File Shredder" which the company says "forensically erases unwanted files you deleted from your device". However the company uses a proprietary algorithm to manage the data, a practice which is prone to error according to many security experts. On January 15, 2014, Wickr announced it is offering a $100,000 bug bounty for those who find vulnerabilities that significantly impact users. In addition, a recipient can in general use other software and techniques like screen-capture capabilities or a separate camera to make permanent copies of the content. In the face of revelations of surveillance programs like the NSA's PRISM, similar applications like Silent Circle (software) and Lavabit designed by Internet privacy pioneers decided to shut down rather than put their users at risk of government-ordered surveillance.
