MacRumors noticed on Monday that Google had finally added the required data collection information to the Gmail app, and it is surprisingly (or maybe not) extensive. There are 10 data categories Gmail collects and shares to improve third-party advertising, analytics, product personalization, and app functionality.
As far as third-party advertising goes, Google only shares your course location, user ID, and advertising data. However, it collects for its own use other information such as contacts, search history, purchase history, photos, video, audio data, and the vague “other user data” and “other data types.”
