We use the permission to access your media and camera to be able to add photos to your forests. When you deny this permission, the app will work but you will not be able to add photos. Also it's not possible to load the photos from the cloud and they will not display in the overview. You will see a generic image to indicate that there is a photo, but that it cannot be loaded.
You can add photos by picking one from the image library or take a new photo. For the latter we need access to your camera so that we can catch the picture taken and save it in the app.
That's it, we do not use it for anything else.
