The suit claims that the iPhone and iPad are "identifying devices" that allow software to track when we download, what we download and many other online behaviors. The devices, according to the suit, have Unique Device Identifier, or UDID.
That data is then allegedly sold to advertising agencies, who can hone their message accordingly.
The suit seeks class-action status and was filed on Dec. 23. It names Apple, Pandora Radio, Paper Toss, the Weather Channel and Dictionary.com as defendants.
“Some apps are also selling additional information to ad networks, including users’ location, age, gender, income, ethnicity, sexual orientation and political views,” according to the suit.
