h5p/Moodle Video Hosting Privacy

Hello,

I'm using the H5P plugin in for Moodle to create an interactive book for a STEM course. Part of the course features videos that come under the Human Tissues Act, so they have to have tight restrictions as to who can view them. If I embed the videos directly into H5P content, where is this stored? H5P servers? Is there more information regarding this? 

Hope it's not too obvious a question! Been reading the Privacy API for Moodle and I know that the "H5P plugin for moodle supports the Privacy API provided by moodle" but I'm still not clear.

Thanks,

Hamish
