As there are many applications that are supported by smartphones, so there is an increasing interest in finding artifacts (digital evidence) created by such applications. Wickr is a free application that allows users to send self-destructing files and messages. It came out as an iOS-only app but now it is launched in “public-beta” for android devices. As claimed by the Wickr app founders, it leaves no traces behind even for forensic investigators. This research focuses on authenticating the claims above. Experiments consisting of various test cases on rooted and non-rooted android devices were performed to investigate whether the traces are left behind or not.
