Apple has been sued this week over "allegedly transmitting user information to advertising networks without the consent of owners" of its iOS devices.
Jonathan Lalo, of Los Angeles, says Apple and a group of mobile app developers sold his personal data (age, sex, location) to ad networks.
Reads the suit: "[Lalo] did not expect, receive notice of, or consent to Defendants' tracking of his iPhone app use and did not want Defendants to engage in such activity."
Apple's policies state that apps are not allowed to transmit data without a user's consent.
The suit comes at a time when the WSJ has broken news that many mobile applications transmit personal data to third party advertisers without user content.
One of the most high-profile apps named is Pandora, the popular Internet radio app.
