Last year, Apple made privacy the central theme of Worldwide Developer Conference with Sign in with Apple, limited location tracking, and Home security. While the company’s announcement of Mac‘s transition from Intel to its own ARM-based CPUs in this time’s keynote, privacy was a pivotal part of the firm’s presentation.

During the keynote, Apple focused on preventing websites and apps from tracking you at multiple points. Starting with iOS 14, iPadOS 14, and tvOS 14, developers will have to explicitly ask for user permission to track them. To be clear, this definition of tracking includes, data collected for ad targeting, location data, and email lists to share with data brokers, and a third-party SDK placed in the app to track user behavior.
