In an open letter to the developer of the mobile application BabyBus, the Federal Trade Commission (“FTC”) asserted that BabyBus, which is directed at children from ages one to six, failed to obtain their parents' consent prior to collecting geolocation information, thereby violating the Children's Online Privacy Protection Act Rule (COPPA).
               
Pursuant to the FTC warning, Google removed the BabyBus application from its Play mobile marketplace. BabyBus developers announced that its Google Play account has been frozen as a response to the FTC's letter, and that they are working to bring their application into compliance with U.S. laws.
