When Apple released iOS 6, one of the few new features not enthusiastically promoted by the company was Identifier for Advertisers (IDFA) ad tracking. It assigned each device a unique identifier used to track browsing activity, information advertisers used to target ads. Even though IDFA is anonymous, it’s still unsettling to people who worry about privacy.
Fortunately, Apple included a way to disable the feature. You won’t find it in the privacy settings, however. Instead, you have to go through a series of obscure options in the general settings menu. Now, “General” is a crappy name for a menu item. It’s mainly a bucket of miscellaneous stuff that they didn’t know what to do with. In the “General” menu, select “About.” Down at the bottom of this menu, next to the terms of service and license items, there’s a menu item listed as “Advertising.”
