Safari's Intelligent Tracking Prevention (ITP) is a privacy feature designed to limit invasive web tracking. It dynamically learns trackers from your browsing history using machine learning. As browsing behavior differs from person to person, so do the identified trackers.
ITP works differently for every user, as it learns from your unique browsing patterns. This personalized approach means that we cannot study it in a lab alone. By donating your anonymous data, you help us audit Safari's automated decisions that affects the privacy of millions of users worldwide.
The data we are interested in is automatically generated by Safari. It is stored locally in a database file on your device. We process the file directly in your browser to extract the relevant insights, ensuring that your raw browsing data never leaves your device. You have full control over what is shared before confirming your donation. Any domain or information you do not wish to share can be easily removed.
The overall process takes 5-10 minutes and requires no technical knowledge. While we do not offer any compensation, your contribution helps improving web privacy for everyone.
We collect a summary of the domains Safari's ITP has observed. We do not collect your full browsing history. Instead, we extract three specific insights:
A list of all domains Safari is currently monitoring in its database. This includes both potential trackers and regular websites you have visited.
Whether you actually used a domain. True if you clicked or interacted with it, false if it only loaded in the background without your direct action.
Which domains were loading while you were visiting others. For example, seeing that pixeltracker.co was active while you were on wikipedia.org.
Your trust is paramount. Here are the strict measures we take to protect your privacy when you donate your ITP data:
We automatically discard any website not found in the global top 10,000 most popular sites. Niche or personal URLs are never collected.
All data processing happens locally in your browser. Before donation, you can review the final data and remove anything you do not wish to share.
We assign a random identifier to your donation. This identifier cannot be linked back to your identity or person.
The extracted data contains no passwords, no search history, no specific page titles, and no form data.
