A vast majority of iPhone users in the United States are choosing not to be tracked by advertisers, with only 4 percent opting in to cross-app ad tracking, according to data highlighted by Mashable.

The low adoption rate underscores a significant consumer shift toward data privacy. When presented with the explicit choice to allow or deny tracking, the overwhelming response from users indicates a strong preference to keep their browsing and app activity private.

This trend represents a notable challenge for digital advertising networks and app developers who rely on tracking user activity to deliver targeted ads and measure marketing performance.
