Apple Tracks Your Activity — Then Scrambles It
If you’re tech-savvy, you may be wondering how Apple’s various systems can learn your behavior and tailor their recommendations without compromising your privacy. In short, Apple does track your activity — but it works to scramble that data.
Apple uses Differential Privacy to achieve this. Essentially, it tracks the behavior of your device usage but scrambles your specific activity and combines it with the data of millions of other people. It sees general patterns among its users, but not your specific usage.
