Safari doubles down on privacy as online tracking gets more intrusive

The modern web runs on data. Every click, search, purchase, and website visit can be collected, analyzed, and used to build detailed profiles of users. While many browsers have gradually introduced privacy features over the years, Apple is continuing to make privacy a core part of Safari’s identity.

One of Safari’s longest-running privacy features is its blocking of third-party cookies. Apple became the first major browser vendor to block all third-party cookies by default in 2019, preventing many advertisers and tracking networks from following users across multiple websites.

Safari’s Intelligent Tracking Prevention (ITP) expands on that protection by using machine learning to identify tracking behavior. Once detected, tracker data is immediately removed, while known trackers are prevented from seeing a user’s IP address. Users can also view Safari’s Privacy Report, which shows how many trackers have been blocked and which websites attempted to use them.

Apple has also focused heavily on combating browser fingerprinting, a technique increasingly used by advertisers and data companies as traditional cookies become less effective. Instead of relying on stored cookies, fingerprinting attempts to identify users through device characteristics such as screen resolution, installed fonts, operating system configurations, and browser settings.

For iCloud+ subscribers, Apple offers another layer of protection through Private Relay alongside the Hide My Email option. The service hides a user’s IP address across Safari browsing sessions, preventing both internet providers and websites from building browsing profiles based on location or network information. Apple says the system is designed so that neither Apple nor the network provider can view a user’s complete browsing activity.

Privacy protections also extend to browser extensions, which have become increasingly powerful over the years. Safari requires extensions to disclose what information they want to access and allows users to limit permissions to specific websites or grant access temporarily. This helps reduce the risk of extensions collecting sensitive information such as passwords, payment details, or browsing activity across multiple sites.

Private Browsing has also received additional protections beyond simply hiding browsing history. Safari blocks trackers during private sessions, applies advanced anti-fingerprinting measures, and prevents websites from storing information that could be used to identify users later. Users can also lock private tabs using Face ID or Touch ID on supported devices.

Another feature aimed at reducing tracking is Link Tracking Protection. Many websites append unique identifiers to URLs that allow companies to monitor users as they move between pages and services. Safari automatically removes many of these tracking parameters when users browse privately, limiting the amount of information shared through links.

Apple has also added the ability to use a different default search engine specifically for Private Browsing sessions, allowing users to separate their everyday searches from searches conducted in private mode.

The emphasis on privacy comes at a time when data collection has become deeply embedded into the online economy. Advertising networks, analytics providers, social media platforms, and data brokers all rely on user information to personalize services and target advertisements. As companies continue looking for new ways to identify users, technologies such as browser fingerprinting have become increasingly common even as traditional cookie tracking declines.

Safari’s approach does not eliminate online tracking entirely, but it reflects a broader effort to limit how much information can be collected without a user’s knowledge. Rather than relying on a single privacy feature, Apple has built multiple layers of protection into the browser, covering cookies, fingerprinting, extensions, URL tracking, IP addresses, and private browsing sessions.

At a time when personal data has become one of the internet’s most valuable commodities, Safari is positioning privacy not as an optional add-on, but as a default part of the browsing experience.
