Purple apps support tracking via several tracking services. Each tracking service usually distinguishes three types of events:

Some tracking services also support attributes. These are fundamentally different from events because they do not represent an event that occurs at a specific time, but describe a state that an user or the app has.

Purple also use this division to reflect the behavior of the tracking services. So action events are described in Action events, view events are described in View events, purchase events are described in Purchase events and finally attributes are described in Attributes.

In addition, Purple divides its content into different content types. What these content types are is described in the chapter Content types.
