When using the GrapevineGo app you need to allow the app to access the smartphone camera in order to scan the QR code that starts the game. In addition, you need to allow the app to know your location so that the app can show your position on the map, as well as the location of the next pin. The data is not used for any other purpose than to deliver a working game to the app user.
