Runkeeper
Runkeeper is a GPS fitness-tracking app for iOS and Android with over 40 million users. First launched in 2008 by CEO Jason Jacobs with the help of "moonlighting engineers". In late 2011 Runkeeper secured $10 million in a Series B financing, led by Spark Capital. In February, 2016, RunKeeper was acquired by ASICS.
In May 2016, the Runkeeper software came to the attention of the Norwegian Consumer Council for breaching European data protection laws. It is alleged to continue tracking user's locations after the application is terminated and to share this information with advertisers in ways that exceed the bounds of the application's terms and conditions.
