"usage" and "content" are part of a list following "information about", so they are collecting information about content, not content itself. What exactly that means in practice, we are all just guessing unless you go and ask them to clarify. Probably things like what settings you used for your videos so they can analyze which features are most popular/worth improving. At least in the EU, if this EULA was not clearly accessible/communicated on the store page before purchase, it would just be invalid, and you'd have a case that the product doesn't work. They're banking on people having more important things to do and just clicking accept to use their product...
