Apple Details Safari Privacy Move and Its Impact on Identity Tracking

October 20, 2026 - 05:58

A month after Apple began blocking ad tech companies in its Safari browser, the company has finally explained the reasoning behind the change. The move targets the tools that identity companies use to follow users across websites, and Apple is making clear that those practices are now in its sights.

The explanation centers on a simple idea: tracking users without their knowledge or consent should not be the default on the web. Apple says the block is meant to stop companies from using hidden techniques to identify devices and rebuild browsing histories. Instead of singling out one vendor, the change applies broadly to the fingerprinting methods that identity firms rely on to recognize users after cookies are cleared or blocked.

For identity companies, the shift is significant. Many of them built their products around the ability to recognize users across sites, and Safari's block removes a key pathway for that work. Some firms argue their methods are transparent and respect user choice, but Apple's position is that the browser should not serve as a backdoor for cross site tracking.

The timing matters as well. Privacy rules and browser limits have been tightening for years, and Apple's latest step adds pressure on an industry already adjusting to a world with fewer tracking signals. Advertisers and publishers that depend on identity graphs will need to rethink how they measure and target audiences in Safari.

Apple has not offered a timeline for further changes, but its message is clear: tracking that happens without explicit user permission will face growing resistance in its browser.
