What You Need to Know About Intelligent Tracking Prevention In iOS 14, iPadOS 14, And Safari 14

Simo Ahava unpacks a lot of info on the topic here are some of the key bits:

• The Privacy Report is available in the Safari 14 browser across Apple’s operating systems (macOS, iOS, iPadOS).
• It uses DuckDuckGo’s Tracker Radar list to enumerate which known tracking-capable domains have been receiving HTTP requests from the sites the user has visited.
• The report highlights how some of the most prominent tracking domains (e.g. facebook.com and doubleclick.net) have been prevented from accessing the user’s browser storage, among other things.
• Since WebKit blocks all access to cookies in third-party context, the full list of “prevented” domains comprises all the cross-site requests done from the sites the user visits, not just those listed in the Privacy Report.
•  all WebKit’s Intelligent Tracking Preventions are on by default in all browsers running WKWebView in iOS 14 and iPad 14.
• Full third-party cookie blocking. All cookie access in third-party context is blocked. There are no exceptions.
• All cross-site referrers are downgraded to just the origin by default (https://www.domain.com).
• All cookies written with JavaScript will have their expiration capped at a maximum of 7 days from the time the cookie is (re)written.
• Safari does not block requests – it strips them of the capability to access cookies or parse referrer headers, etc.
