The app Snapchat lets users share photos with friends and then users choose to give an expiration time limit for the photo. It turns out that the photos don’t always permanently delete. An internet safety company, Decipher Forensics, discovered that the app actually stores the images. Richard Hickman who works for the company said, “We wanted to know if ‘snaps’ really do ‘disappear forever. If there is metadata associated with ‘snaps,’ if ‘snaps’ can be recovered after becoming expired, and if they can be recovered, if there is metadata associated with the expired ‘snap.'” The app creates a file on your phone and stores the photos in a file called NOMEDIA.
