Snapchat is a photo messaging application developed by Stanford University students. Using the app, users can take photos, record videos, add text and drawings, and send them to a controlled list of recipients. These sent photographs and videos are known as "Snaps". Users set a time limit for how long recipients can view their Snaps, ranging from up to 10 seconds to as little as 1 second, after which they will be hidden from the recipient's device and they are also deleted from snapchat server. As of August 8, 2013, a Windows Phone app does not exist for Snapchat.
