Download and privacy analysis of iOS and Android apps at scale.

The development of PlatformControl was led by Konrad Kollnig from the Computer Science Department, University of Oxford.



The above figure shows a schematic overview of how this repository was used in a past research paper. For details, please see the corresponding publication: Are iPhones Really Better for Privacy? A Comparative Study of iOS and Android Apps


This project has multiple parts:

  1. - To explore what iOS and Android apps are on the app stores, and also for the download of Android apps, as well as a high level analysis of iOS and Android apps (permissions, mainly).
  2. - Required for the downloading of Android apps at scale.
  3. - To download iOS apps at scale from the App Store.
  4. - For the analysis of tracking libraries and contacted tracking domains, for both iOS and Android
  5. - To disable certificate pinning in Android apps

Ready-to-use analysis with TrackerControl

As a sub project of PlatformControl, TrackerControl is an indepedent and somewhat popular Android app to privacy analysis and control. It contains some of the core analysis functionality of PlatformControl (though by far not all of it), conducting both network traffic and tracker library analysis.
