geolocation data end-users

This post discusses some of the contractual requirements imposed by Apple and Google regarding the collection and sharing of locational information.  What consents, if any, do Apple and Google require that app publishers obtain before collecting and using locational information?  This is a question that is being asked with increasing frequency.  In fact, a regular beat of media coverage on the issue  (see, e.g., here or here), has reached crescendo levels with a much-discussed article this past week in the New York Times. Coincidentally (or maybe not?), the NYT article was published the day before Google CEO Sundar Pichai testified before the House Judiciary Committee on Google’s privacy and data collection practices, among other things.
