Google Play requires us to disclose what permissions this app requires and why they are required:
Internet access: As most of the content are hosted on external servers, we require that the app can access the internet and download the content and store it locally on the phone.
Sensor: When displaying the compass, we rely on the sensors within the phone, and therefore need permission to use the sensors. These data are only used in-app and are not distributed, shared or stored.
Location: In order to determine your location and display the distance between you and the POIs and routes, we require the location permission. These data are only used in-app and are not distributed, shared or stored.
Camera: On the detail descriptions of the POIs, its possible to take personal pictures, which are placed in the phones default photo storage. This option requires permissions to use the camera. These pictures are only for the user and they are not used, distributed or shared by the app.
Bluetooth: This app requires access to the Bluetooth device, as IBeacon are a part of the experience. The beacons transmit data which the app receives and uses it to calculate the distance between the phone and the beacon device. These data are only used in-app and are not distributed, shared or stored.
