iPhone Apps No Better For Privacy Than Android, Oxford Study Finds

An anonymous reader quotes a report from Tom's Guide: A new survey has reached a startling conclusion: iPhone apps tend to violate your privacy just as often as Android apps do. "Overall, we find that neither platform is clearly better than the other for privacy across the dimensions we studied," say the academic paper entitled "Are iPhones Really Better for Privacy?" and presented by researchers from the University of Oxford. "While it has been argued that the choice of smartphone architecture might protect user privacy, no clear winner between iOS and Android emerges from our analysis," the paper adds. "Data sharing for tracking purposes was common on both platforms." There's one big caveat regarding the new study: It was conducted before the introduction of iOS 14.5 in April 2021, which made opt-in to tracking and app privacy labels mandatory on iPhones. The researchers analyzed the code, permissions and network traffic of 12,000 randomly selected free apps from each platform that had been updated or released in 2018 or later. Each app was run on a real device, either a first-generation iPhone SE running iOS 14.2 or a Google Nexus 5 running Android 7 Nougat. They found that nearly all (89%) of the Android apps contained at least one tracking library, which was almost always Google Play Services. The numbers weren't much lower on iOS, where 79% of apps had at least one tracking library, most likely Apple's own SKADNetwork, which tracks which ads a user clicks on. However, 62% of iOS apps also ran Google's AdMob ad tracking library, followed by 54% of iOS apps (and 58% of Android apps) running Google Firebase. Facebook trackers were in 28% of Android apps and 26% of iOS ones. In fact, most apps on either platforms -- 90% of Android apps and more than 60% of iOS -- shared data with tracking companies owned by Google. Almost all tracking companies observed were based in the U.S. About 9.5% of iOS apps and 5% of Android ones used Chinese-based trackers; 7.5% of iOS apps and 2% of Android ones used Indian trackers. The team commended Apple for making it possible for iPhone users to block the temporary advertising IDs that flag your phone to advertisers, but the team also saw an ulterior motive on Apple's part. "Apple's crackdown on Ad ID use could be interpreted as an attempt to divert revenue from Google and other advertising providers, and motivate the use of alternative monetization models -- which are more lucrative for Apple," the Oxford research paper states. "Apple has arguably placed a larger emphasis on privacy, seeking to gain a competitive advantage by appealing to privacy-concerned consumers."
