SnapChat is an application developed by Daniel Smith and his team at Stanford University that enables users to take pictures and record videos then, if desired, add captions to them and send them to selected individuals.

SnapChat allows users to take pictures and videos called "snaps." Users can set a time limit, after which the picture or the video is removed from the SnapChat server and the recipient’s device. This provides security for users who are concerned their images may be stored on the Internet or used without their permission.
