Privacy groups have complained to the Federal Trade Commission that Google is encroaching on user privacy through a policy change in June that allows it to combine personally-identifiable information with browsing data collected by its DoubleClick digital advertising service.

The complaint by Consumer Watchdog and Privacy Rights Clearing House alleged that Google has created “super-profiles” as it can track user activity on Android mobile phones, with an 88 percent market share of smartphones worldwide, “and from any website that uses Google Analytics, hosts YouTube videos, or displays ads served by DoubleClick or AdSense.”
