One of Apple’s more contentious new features is finally available in the recent iOS and iPadOS 14.5 update. It’s not contentious to users, but to companies like Facebook, who make money from tracking you across apps and websites, it represents a real challenge. Here’s how to ensure that Facebook and others can’t track you, and why you should. <\/p>\n

Cross-site tracking<\/h3>\n

Facebook’s business model is serving ads, and to do this efficiently – so the company says – they want to be able to personalize those ads based on your interests and activity. They get much of that information from your Facebook activity: what you post, what you like, what groups or pages you visit, and more. However, the company also leverages activity that is not carried out on Facebook in order to build a more detailed profile of you. <\/p>\n

Facebook does this in several ways. One is using the "Facebook pixel<\/a>," a bit of javascript code on websites that recognizes users, and adds which websites and types of pages they view to their profiles. If you search for cat litter across several websites, Facebook will know you’re really into cat litter, and will likely present ads about cat litter, cat food, cat toys, etc.<\/p>\n

Another way is in iOS apps. These apps use frameworks from Facebook<\/a> to display ads, but these frameworks also collect data and send it to Facebook’s servers. This depends on the ability to track users across apps, in order to build a detailed profile. Knowing the types of apps you use, and how you use them, is valuably to advertisers. <\/p>\n

If you want to be surprised, have a look at your "off-Facebook activity<\/a>" to see what Facebook knowns about you. <\/p>\n

Empowering users<\/h3>\n

Apple has cracked down on this cross-site and cross-app tracking, and in iOS 14.5, a new feature requires that apps request permission to track you<\/a>. <\/p>\n

\"\"<\/p>\n

You can, should you choose to do so, allow specific apps to track your activity by tapping Allow when you see dialogs like the one above, but there’s no real reason to do so. It’s not just Facebook that benefits from this, but other companies such as Google, and data brokers, who build user profiles and sell them to advertisers. <\/p>\n

By default, the setting to allow apps to ask your permission is off; that means that apps will not ask if they can track you, and they should not track you. (They could still do so, surreptitiously, but if Apple finds out, they’ll be in trouble.) You can check this option in Settings > Privacy > Tracking. <\/p>\n

\"\"<\/p>\n

If the toggle is off, as in the above screenshot, apps won’t ask you if they can track you. <\/p>\n

In some cases, this option is fully disabled, and is greyed out. This is the case: <\/p>\n
