"We may ask for your permission to access your device's photo file or gallery app, camera and audio recording tools, to provide certain services, when you are using the Application, such as to generate Output for photos you share or to transcribe your audio recording. We may collect data about the device you use to interact with our Services, including the device name, device ID, its model, its manufacturer, region information, device's operating system, device identifiers, hardware model."
The app requests access to camera, microphone, photo gallery, and collects extensive device identifiers and hardware information. While some access supports core features, the breadth of device data collected (device ID, hardware model, manufacturer, OS) goes beyond what a language learning app strictly requires.
