Apple has been slapped with a class action lawsuit that accuses the company and several prominent app makers of sharing users’ personal identification without consumers’ approval.

Jonathan Lalo filed his complaint in California district court last week, accusing Apple of producing devices that allow ad networks to track a user’s app activity.

The entire complaint has not yet been posted online, but it cites Backflip, Dictionary.Com, Pandora, and The Weather Channel as some of the offending apps.

“Some apps are also selling additional information to ad networks, including users’ location, age, gender, income, ethnicity, sexual orientation and political views,” the suit said, according to Bloomberg.

The case centers around the use of the Unique Device Identifier, or UDID, on Apple’s iPhones and iPads. The suit complains that the UDID can’t be blocked by consumers and that Apple shares that info with ad networks and advertisers. Apple says otherwise and that it makes sure that users can’t be “tracked” by marketers through the UDID or anything else without consumers’ permission.
