Developer note — I'm the parent who built YumTube, with help from ChatGPT. My seven-year-old daughter wasn't chewing much at meals, which led me to try a parent-guided video player.

Parents choose a YouTube link and session time. On-device mouth movement controls pause/resume; it cannot tell whether food was eaten or swallowed. Camera frames and face coordinates are not stored or uploaded by the app. YouTube has separate data and advertising rules.

I'd welcome feedback on whether the first-use setup and pause/resume delay are clear.
