Most people in the U.S. may not care much but the Android version of Runkeeper trackers you and sends back location data even when you aren't using the app.
Runkeeper background tracking leads to complaint from privacy watchdog | Ars Technica

America is a little more skewed in favor of business and corporations. We take it for granted that our every move is tracked and catalogued by companies hoping to make a buck. ;)
