This handout image provided by the Federal Trade Commission (FTC) shows the cover of the FTC's “Mobile Apps for Kids: Disclosures Still Not Making the Grade" guide. The FTC is investigating an unspecified number of software companies that make cellphone apps to determine whether they have violated the privacy rights of children by quietly collecting personal information from their phones then sharing it with advertisers and data brokers, the agency said. Such apps can capture a child's physical location, phone numbers of their friends and more. (Associated Press/FTC)
