Bug Fixes, Improvements, ..., and Privacy Leaks

A Longitudinal Study of PII Leaks Across Android App Versions


Table 7. Third-party domain trackings

Third-party domains track mostly different unique identifiers and there is little correlation between the number of contacted flows and the number of flows having PII. We group the following domains as google[*]: google.com, googleapis.com, doubleclick.net, google-analytics.com, gstatic.com, googleusercontent.com, googleadservices.com.
