Intelligent Tracking Prevention is the name of the tracking prevention mechanism implemented in WebKit and enabled in Safari and all major browsers running on the iOS platform. I’ve written about it on this blog, and the CookieStatus.com resource is something you should bookmark for further reading. The purpose of ITP is to prevent tracking tools’ access to data stored and processed in the browser. This involves things like blocking all third-party cookies and restricting the lifetime of first-party cookies.
Apple’s annual Worldwide Developer Conference in late June this year included a couple of big announcements around Apple’s approach to privacy in their software. The new Privacy Report in Safari 14 (on all platforms) uses DuckDuckGo’s tracker radar list to detail which of the most prominent tracking-capable domains have been flagged by Intelligent Tracking Prevention (ITP) in the user’s browser. Apple also announced that the WKWebView class, which all iOS and iPadOS (the operating systems for iPhones and iPads, respectively) must use, will include WebKit’s ITP mechanisms on by default.
