The IBM-owned Weather Channel app has been transmitting its users' precise geolocation data to advertisers and other third parties despite telling users that their location data was needed only for providing local weather data, according to a lawsuit filed Thursday by California government officials.

When asking users for permission to turn on location tracking, the iOS and Android app does not "give users any reason to believe that their location data will be used for anything other than personalized local weather data, alerts and forecasts," the lawsuit said.
