iOS 17 Automatically Removes Tracking Parameters From URLs in Safari Private Browser, Messages, and Mail

Starting with iOS 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.

Apple calls this new feature Link Tracking Protection, and it also works for links shared in the Messages and Mail apps. The links will still work as expected, but will no longer have unique identifiers embedded into the URL for tracking purposes.

In a WWDC 2023 video for developers, Apple shared an example of a URL before and after the tracking parameters are removed. The original URL has a unique “click_id” parameter that advertisers can use to track a user’s activity across websites. Safari automatically removes this parameter to protect the user’s privacy.

iOS 17 and macOS Sonoma will be released later this year, and are currently available in beta for users with an Apple developer account.
