The app allows you to determine your footsize and preview the foot scans before you submit your scans. The app asks permission to use your camera (front-facing). When you allow the app to use the camera, the permission to use the depth-sensing camera is also provided. The app does not store, collect, or transfer any picture or video data out of your phone. Instead, the app generates and uploads a 3D model of your feet (in form of point clouds) to our servers when you initiate such an upload explicitly.
