Google has rolled out a minor privacy update for Android devices. If you open the latest version of the Android Market and hit the settings button, there’s a new check-box that elts you opt-out of “interest-based ads” from Google and AdMob.
This won’t let you opt out of all in-app advertisements. But it does mean that if you download an app that uses Google’s advertising service, the ads won’t use information Google has gathered about you to present targeted ads based on your interests or demographic information.
Not all in-app advertising comes from Google or AdMob, so this doesn’t give you total privacy control, but it’s certainly a start — and it’s more control than you get on some mobile platforms.
