The internet isn’t private, but that doesn’t mean you have to willingly give up all of your information to use it. By default, trackers steal a lot of your data while you browse the web, but simple settings can block a lot of those trackers from functioning. As it turns out, by updating to iOS 26 , your iPhone gets an upgraded tool against tracking.
The feature, called Advanced Tracking and Fingerprinting Protection, is an option in Safari that hides certain browser and device data trackers typically use to build a digital “fingerprint” of users . In this case, a fingerprint is a profile companies use to track your movements across the web. Your fingerprint may be made up of data like your device’s IP address, the device itself, your browser, fonts, plug-ins, as well as its screen resolution. All of these data points come together to build a unique picture of who you are; the more unique your fingerprint, the easier it is to track you , since the odds of someone else with your exact same details is slim.
Fingerprinting has a number of applications across the web, but perhaps the largest is for targeted advertising. The reason many of the ads you see are so relevant to your interests and browsing history is because of fingerprinting. Trackers know your internet habits, and can identify and deliver the advertisements you’re most likely to click or tap on. Companies can also sell these fingerprinting profiles to brokers and advertisers, making money on both your engagement with ads, as well as your raw data.
Advanced Tracking and Fingerprinting Protection simplifies each Safari user’s data, so our fingerprints aren’t quite so unique. By doing so, it’s harder for trackers to identify individuals, and, as such, makes it possible to browser the web more privately.
This feature was already a thing on iPhone before iOS 26. However, it was limited to Private Browsing by default. If you didn’t do all your browsing in a private tab, you likely lost some of these privacy protections, unless you knew to manually change the setting to cover all browsing. The same goes for iPadOS and macOS as well. Most of us probably didn’t change the setting, since it’s quite buried in each OS’ respective settings.
Once you update your iPhone, iPad, or Mac to the latest OS, however, your browsing gets these added tracking protections by default. Whether you browse in a private or a normal window, trackers will have a difficult time identifying your device.
How to check your Advanced Tracking and Fingerprinting Protection settings
This setting should be enabled by default when you update your device. But if you want to make sure it’s on, here’s where to find it. On your iPhone or iPad, open Settings, then head to Apps > Safari > Advanced. On your Mac, open Safari, press Command + , to pull up Safari’s settings, then choose the Advanced tab.
From here, ensure Advanced Tracking and Fingerprinting Protection is set to “All Browsing” (iOS/iPadOS) or “in all browsing” (macOS).
