Intelligent Tracking Prevention
You may have noticed that when you look at something to buy online, you suddenly start seeing it everywhere else you go on the web. This happens when a third party tracks cookies and other website data to show you ads across various websites. Intelligent Tracking Prevention uses the latest in machine learning and on-device intelligence to fight this cross-site tracking. It works by separating the third-party content used to track you from other browsing data, so what you look at on the web remains your business — not an advertiser’s. And you don’t have to change any settings for these protections because Intelligent Tracking Prevention is on by default.
Your Privacy Report shows you all the cross-site trackers that are being blocked by Intelligent Tracking Prevention in Safari. You can access your report from the Safari toolbar and the Safari start page.
Safari checks to see whether your saved Keychain passwords have been compromised in data breaches. It uses secure and private cryptographic techniques to regularly check derivations of your passwords against a publicly available list of breached passwords. If Safari identifies a potentially compromised password, your device will notify you. Your password information is never revealed as part of this process — not even to Apple.
Social widget tracking prevention
Social widgets embedded on websites, such as like buttons, share buttons, and comment fields, can be used to track you even if you don’t click them or use them. Safari blocks this tracking by default, and it prevents social widgets from accessing your identity unless you grant them permission.
Safari works to prevent advertisers and websites from using the unique combination of characteristics of your device to create a “fingerprint” to track you. These characteristics include the device and browser configuration, and fonts and plug-ins you have installed. To combat fingerprinting, Safari presents a simplified version of the system configuration so more devices look identical to trackers, making it harder to single yours out. This protection is on by default, so there are no extra steps for you to take.
When you turn on Private Browsing, Safari won’t add the sites you visit to your history, remember your searches, or save any information from forms you fill out online. You can use content blockers to control what’s loaded onto your browser and to prevent anyone from attempting to track your activity on a website or across websites. Content blocker support is designed so that it can’t send developers information about what you’re looking at.
With the Smart Search field in Safari, you can type website names, web addresses, and search queries all in one place. Safari minimizes the amount of data sent to third-party search engines — for example, it won’t share cookies or your precise location, which may happen if you search by other means. Safari also offers the option to set DuckDuckGo as your default search engine, allowing you to search the web without being tracked.
Browser extensions can help you do many things, like saving money on purchases or improving your grammar. However, they can also be used to track you, taking note of what you browse and even what you type. With Safari extension controls, you can grant extensions access to your information just for one day, just for this current website, or always.
