Although Gruber is summing it up based on a developer's words, they do state this ridiculous data collection in their privacy policy (which is an implied agreement, based on your downloading of the app).

We also collect pictures, videos, comments, and actions you take through the App (“Content”), and information on your location. When our App is active, your Device provides periodic updates to our server of your location, which allows us to show you fresh Content based upon where you are at that moment. We share your Content with others. Sharing Content publicly with others from different locations is what this App is about. If you find this objectionable, please consider not using our App or Site.
