Ads an undeclared in-app purchases – Video Cache - Editor & Maker Review

I need to download YouTube videos for education- YouTube is being blocked since it recommends videos that aren't what teachers ask for. So I want the videos I was showing before, but outside of a YouTube framework...preferably straight into my iPads storage. I figure since it is for showing to a class, not for profit, legality is resolved. This app seemed like it might work, but presented a full screen ad upon open, and then clicking upon Internet video downloaded led to an ugly page with a request for 3.99. in App Store, no in-app purchases are listed, and this just seemed SCAMMY. NO THANK YOU.
