From the good folks at EPIC:
EPIC filed a complaint with the Federal Trade Commission against Snapchat, the publisher of a mobile app that encourages user to share intimate photos and videos. The company represents that users can make photos and videos “disappear forever.” In fact, the photos can be retrieved by others after they should have vanished. The EPIC complaint implicates Privacy Enhancing Technologies, which if properly implemented would minimize or eliminate the collection of personally identifiable information. The FTC described similar methods in a 2012 privacy report. Previously, EPIC filed a complaint at the FTC against AskEraser, which falsely represented that search queries would be deleted when in fact they were retained by the company and made available to law enforcement agencies.
