Some people aren't bothered by the idea that all of their electronics devices are tracking their behavior on behalf of advertisers. But if you're an Apple iPhone user and you'd rather not receive behaviorally targeted advertising, there's something you can do about it. You can turn it off.
There's a simple menu setting three levels deep into the settings of iOS that gives users a degree of control over just how much information Apple's iAds send out to advertisers. Here's where to find it.
Find the Privacy menu in settings.
Scroll all the way down to the bottom of the Privacy menu to find the Advertising submenu.
In the Advertising submenu, you'll find a switch allowing you to "Limit Ad Tracking," and the default setting is off. It may feel counterintuitive to turn on a setting for ad tracking in order to prevent it, but that's what you'll want to do here.
If you want to learn more about exactly what the iAd tracking is doing, Apple explains it when you click "About Advertising & Privacy". Tap it and a page pops up describing how Apple's "Advertising Identifiers" work.
By the way, if you'd like to limit ad tracking on your Apple TV and in the iTunes Store, you can do that, too. Here are Apple's instructions on how to do so.
