Snapchat is a video messaging application. Using the application, 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 (as of March 2015, the range is from 1 to 10 seconds), after which they will be hidden from the recipient’s device and deleted from Snapchat’s servers. Parents should be aware of this app as they may not know what “Snaps” their children are sending and to whom as they will disappear after a certain time.
