As many as 256 iPhone, iPod touch and iPad applications in the App Store, a majority of them from Chinese developers, have been found to violate Apple's privacy policy by gathering personal information such as email addresses, installed apps and even serial numbers, an analysis by security analytics startup SourceDNA has found out.
In addition, the offending apps, which obviously went under the radar of Apple's App Store editorial team, have been found to collect other personally identifying information that can be used to track users.
