Answer 1

Devices usually have trackers that will pull information to make “experiences” better. Often times apps will pull from this information to give better results to customers.

Example: I search Dog Bed in google. Facebook pulls data from my device saying I was looking for dog beds on google and uses it to tailor ads for Dog Beds.
