As a team of researchers at Carnegie Mellon University, we collected network traces from thousands of apps, and analyzed them into categories of data types. In this website we present data visualizations showing the data collected by different apps, where the data is being sent.
The most common way for smartphone apps to communicate with cloud servers is through HTTP(S) requests. Therefore, we built a custom VPN to intercept these network traces.
