  Privacy nutrition labels provide a way to understand an app's key data
practices without reading the long and hard-to-read privacy policies. Recently,
the app distribution platforms for iOS(Apple) and Android(Google) have
implemented mandates requiring app developers to fill privacy nutrition labels
highlighting their privacy practices such as data collection, data sharing, and
security practices. These privacy labels contain very fine-grained information
about the apps' data practices such as the data types and purposes associated
with each data type. This provides us with a unique vantage point from which we
can understand apps' data practices at scale.
