Also identify any privacy practices mentioned: Take better pictures by using face detection and other analytics on what's in your viewfinder to deliver the best image, which may occur before or after you triggered the shutter. You can compare the best image with the original picture you captured in Gallery and select which images to keep. Face detection information stays on your phone and doesn't get uploaded to Motorola or shared with third parties. To help us troubleshoot performance issues, Camera will store image quality information in your photos' metadata. Sharing the photos will also share image quality information."}, {'role': 'assistant', 'content': 'This clause is fair. The privacy practices mentioned are: nan.'}]
