Definition of Third-party Advertising under data collection purpose
I see that under the App Privacy section, some apps such as the Google app on the App Store collect only "Data Linked to You" and my understanding is that this is first-party data that is not shared with third parties. When you click on see details one of the data use purposes is "Third-party Advertising" which Apple describes as “displaying third-party ads or sharing data with entities that display third-party ads”
I would like to know about the second part of the definition. Does it mean entities within that app's company (e.g. Google) or third-party entities?
I appreciate your help :)
