What is Intelligent Tracking Prevention in Safari?
Jul 29, 2025 am 01:01 AMIntelligent Tracking Prevention (ITP) in Safari is Apple’s privacy feature that limits cross-site tracking by analyzing browsing behavior and restricting cookies. 1. It uses machine learning to identify trackers based on user interaction patterns. 2. Sites with no direct user engagement are limited in tracking ability. 3. Cookies from inactive sites lose functionality after 7 days. 4. Partitioned cookies cannot be shared across sites. 5. localStorage access is restricted for third-party scripts. For users, ITP enhances privacy but may cause unexpected logouts or less personalized ads. For advertisers, it shortens cookie lifespans and complicates retargeting efforts. To work around ITP, developers should encourage direct interaction, use first-party contexts, redirect instead of embedding, and keep interactions recent to reset the tracking timer.
Intelligent Tracking Prevention (ITP) in Safari is Apple’s built-in privacy feature designed to limit cross-site tracking by websites and advertisers. It uses machine learning to identify tracking behaviors and restricts how cookies and other website data are used, especially when a user isn’t interacting directly with a site.

How Does ITP Identify Trackers?
Safari’s ITP doesn’t just block all third-party cookies outright — it analyzes browsing behavior to determine what might be tracking you across the web.
- Engagement matters: If you don’t interact with a website (like clicking, typing, or watching media), Safari assumes you’re not interested and limits that site’s ability to track you later.
- Machine learning helps: ITP learns from how users typically browse and flags domains that behave like trackers based on patterns.
- Time-based restrictions: Sites you haven’t visited recently lose access to full cookie functionality after about 7 days.
This means even if a site tries to set a cookie, Safari may treat it as a “partitioned” cookie — one that can’t be shared or used for tracking across other sites.

What ITP Means for Users
For everyday browsing, ITP works quietly in the background. Most people won’t notice it unless they run into issues like:
- Logging out of sites unexpectedly
- Seeing more ads that aren’t personalized
- Some features breaking on sites that rely heavily on third-party scripts
The upside is stronger privacy protection without needing extra extensions or settings. You still get a personalized experience on sites you actively use, but not at the cost of being followed around the web.

How ITP Affects Websites and Advertisers
If you're a developer or marketer, ITP has changed how tracking and advertising work online — especially for those using Safari.
- Shorter cookie lifespans: First-party cookies last up to 7 days unless the user interacts with the domain again.
- Storage partitioning: Cookies from embedded content (like social buttons or ads) are stored separately and can’t easily track users across sites.
- Limited access to localStorage: Scripts from third-party domains have reduced access to data storage unless the user engages directly.
So, retargeting campaigns or analytics tools that rely on long-term cookies may not work as expected in Safari without adjustments like redirecting users through first-party flows.
How to Work Around ITP (If You Need To)
If you manage a site affected by ITP, here are some common strategies:
- Encourage direct interaction: Make sure users click, log in, or otherwise engage with your content.
- Use first-party contexts: Avoid relying on third-party iframes or scripts for critical functions.
- Redirect instead of embedding: Send users to your domain directly rather than loading content via iframe.
- Keep interactions recent: Regular engagement resets the 7-day timer Safari uses for tracking limitations.
These approaches help maintain functionality while staying within Safari’s privacy rules.
That’s basically how Intelligent Tracking Prevention works — it’s not foolproof, but it does make tracking harder without making your browsing feel too restricted.
