The U.S. Federal Trade Commission has sent warning letters to 12 smartphone app developers for allegedly compromising users’ privacy. The software, from an Indian company called SilverPush, allows apps to use the smartphone’s microphone to listen to nearby TV audio. SilverPush allows the apps to surreptitiously monitor the television viewing habits of people who downloaded apps with the software included, the FTC said. The apps apparently packaging SilverPush don’t provide users’ notice that they could monitor TV viewing habits, the agency said.”]
