Deactivating info on the page?

Recently we have started to see the statistics for a news article on the bottom and I don’t know why. Since we are using german version of it and only options that are available are basically with on/off marked without any explanations.

On the bottom of an article, there is a statistic on total visits and visits per day. How do I turn it off or at least set it to that logged in users can see it only?
