iOS 17 Can Automatically Remove Tracking Parameters From URLs in Safari, Messages, and Mail
Starting with iOS 17, iPadOS 17, and macOS Sonoma, Safari automatically removes tracking parameters from URLs while in Private Browsing Mode, in order to prevent cross-website tracking. When a tracking parameter is detected while browsing or copying a link, Apple says Safari strips the identifying components of the URL, while leaving the rest intact. The links will still work as expected, but will no longer have unique identifiers.
Apple calls this new feature Advanced Tracking and Fingerprinting Protection, and it also works for links shared in the Messages and Mail apps. It can even be enabled for regular Safari browsing..
