No, your iPhone isn’t secretly recording your conversations. But it is being tracked in ways most people never realize. A technology called digital fingerprinting now allows companies to follow you across the web without your knowledge—and without your consent.

What Is Digital Fingerprinting?

Unlike cookies, which you can delete, a digital fingerprint is permanent. It’s built from details like your IP address, device model, operating system, time zone, and even your phone’s setup. Alone, each detail seems harmless. Together, they create a unique signature that identifies you everywhere you go online.

Even if you avoid Google Chrome and stick with Safari for privacy, Google can still collect your fingerprint whenever you interact with its services. Once combined with data from smart TVs, game consoles, and other connected devices, it builds a remarkably detailed profile of your life.

Google’s Flip-Flop

Not long ago, Google admitted that fingerprinting was wrong, warning that it undermined user choice. But just as it reversed its plan to eliminate cookies, the company has also walked back its stance on fingerprinting—bringing it back into play across its ecosystem.

Apple’s Counterattack

Apple is pushing back in iOS 26 with Advanced Tracking and Fingerprinting Protection.

You’ll find it in Safari under Settings → Advanced.
Right now, it’s limited to Private Browsing, but starting with iOS 26 (launching September 16), it will default to All Browsing.

This feature works by flooding trackers with junk data, making it far harder to single out your device. It won’t stop fingerprinting completely, but it levels the playing field in a way cookies never could.

And that’s just one of the privacy boosts in iOS 26. Apple is also rolling out:

Call Screening: Automatically filters out suspected scam calls.
Message Filtering: Keeps spam and phishing texts out of your inbox.
Link Tracking Protection: Strips hidden identifiers from URLs so they can’t follow you—or the people you share links with.

Why It Matters

Fingerprinting is invasive because you can’t opt out. Regulators have called it “unfair” and a major blow to personal control over data. Apple’s move to make protection the default is a big step in giving iPhone users that control back.

Of course, fingerprinting isn’t limited to Safari. It’s used across apps, platforms, and even smart devices. Still, Apple’s approach sets a new privacy standard—one Google may be forced to respond to, despite tracking being central to its business model.

For now, you can take action yourself: head into your Safari settings and switch fingerprinting protection from Private Browsing to All Browsing. It’s one click that makes a big difference.
