Apple rolled out a major privacy feature on Monday that will allow iOS users to decide how they want their personal data handled — a move that has worried some companies, including Facebook.

iOS users must now give explicit permission for apps to track their behavior and sell their personal data, such as age, location, spending habits and health information, to advertisers. While many apps have allowed people to manage or opt-out of this for years, it’s typically buried deep in user settings and wordy privacy policies.
