How does AI Background Removal work offline?
On Android, the AI model is powered by Google Play Services official on-device machine learning library. When you first install or open the app, Google Play Services initializes and caches the local model library. Once initialized, all background removal, face detection, and image editing execute 100% locally on your phone processor without sending any photos to external servers.
Do my photos ever get uploaded to any cloud server?
Never. All photo processing, face framing, background changes, and exports happen locally on your phone hardware. Your personal photos are never transmitted or stored on external cloud servers, and the app works completely in Airplane Mode.
