Minimal allow list:  
None. (uTheory uses Vimeo/Akamaized for adaptive bitrate video for the video lessons. If either is on your deny list, uTheory will fall back to loading lesson videos from [https://utheory.com](https://utheory.com/?ref=ghost-new.utheory.com); however, they will not be streamed at adaptive bit rates, so the user experience may be diminished for students.)
