A team of researchers from Carnegie Mellon University have assigned privacy grades to Android apps based on some techniques they to analyze to their privacy-related behaviors. Learn more here or browse their analyzed apps.
Grades are assigned using a privacy model that they built. This privacy model measures the gap between
people's expectations of an app's behavior and the app's actual behavior.
For example, according to
studies they conducted, most people don't expect games like Cut the Rope to use location data, but
many of them actually do. This kind of surprise is represented in their privacy model as a penalty to an
app’s overall privacy grade. In contrast, most people do expect apps like Google Maps to use location
data. This lack of surprise is represented in their privacy model as a small or no penalty. more
