A lot or a little?
Parents need to know that Green Screen by Do Ink lets kids create movies and pictures using green-screen technology, as with movie special effects or weather reports. It requires some prep work -- watching the tutorial video, reading instructions, finding something to use as a green screen, and gathering background images -- but it's pretty easy to pick up and create impressive images. Creations are saved to the camera roll, and kids share from there. While there could be privacy issues involved with kids sending their creations outside of the app, the videos are stored locally on the device and not in the cloud or with the developer. Read the developer's privacy policy for details on how your (or your kids') information is collected, used, and shared and any choices you may have in the matter, and note that privacy policies and terms of service frequently change.
