One of the biggest new features of Apple’s new operating system, iOS 4, is the iAds mobile advertising system. iAds will show you full-screen ads within apps on your iPhone or iPod touch. Like most other advertising these days, iAds are also targeted based on data collected about you from your phone usage – so, for example, if you’re searching for nearby pizza joints, you’ll probably see pizza-related ads. But what if you don’t want iAds to be collecting your personal information to tailor the ads you see?
Fortunately, Apple has provided a quick way to opt out of “interest-based” advertising if you’d prefer not to share your data with iAds. You will still see ads on your device, but they won’t be targeted based on personal information (although they still might be related to the content of the application you’re running). Just point your iOS4 device’s web browser to http://oo.apple.com. You should see a message telling you that the opt-out was successful. If you have more than one device running iOS 4, you must opt-out individually for each device.
It’s worth noting that this opt out does not affect the collection of location-based data – though Apple assures us that location information is collected anonymously and safely.
