Find The Invisible Cows In Augmented Reality app does not collect or store any information of any kind.
The app has been produced using the Unity framework and uses the default Camera access permissions. The camera permission is required to show the Augmented Reality backdrop via the internal smartphone camera. No data is stored or otherwise produced from the camera feed.
On Android it will request access to photos and media - the app does not use this access but this was necessary for Unity to function with the camera. As this app was produced in a few hours at a hackathon, there was no time to discover why Unity added this redundant permission.
