I already know the answer to this but I'm asking because it took me a few hours to find it and want to make this easily available for others.
As of December 8, 2020, Apple has made it mandatory for developers to release what data is being collected and what it's being used for. If developers don't comply, they won't be able to publish new apps or release updates for current apps.
So the question is: What data does Google Admob collect and how does it use it?
