WASHINGTON — You think you know what your smartphone can do. But it’s doing a lot more than you realize — or might want.

Every app on your phone is collecting and sending data about you without telling you — sometimes, even when you’re not using the app.

Some apps can even upload and download so much data that you exceed your data cap. But Wired reports that SpyAware, a new tool for Android phones, can keep track. You can’t change what your phone sends out about you, but unlike some tools that can do that, Wired says, it’ll work on any Android phone.

For free, the app gives your phone a score based on the overall risk assessment. For a $3 upgrade, you can get even more information on how the apps collect your location information and where they send the data.
