SUMMARY - How Companies Collect and Use Data
A person browses a website for running shoes and sees ads for those exact shoes across dozens of unrelated sites for weeks afterward. They did not provide their email, create an account, or consciously share any information. A free app requests permission to access contacts, location, microphone, and storage for features that seem unrelated to those permissions. A smart TV monitors viewing habits and sells that information to advertisers and data brokers.
