Apple periodically updates its privacy policy to highlight new additions or to provide more transparency. For example, in November 2019 this took the form of a site design that covered hot-button topics like device tracking and message interception, as well as white papers going into deeper technical details for important elements.
For December 2020, the privacy changes are more muted but arguably more important to end users, as it centers around a new element of the App Store experience. On December 8, Apple started to require developers to advise of the different types of data collected by apps, and what the data is used for.
