When using Mangadex on chrom mobile I'm given the option to download an app version of the site. Is this sanctioned?

Yes, it is. It's a Progressive Web App (PWA) to be precise.

A progressive web app (PWA) is an app that's built using web platform technologies, but that provides a user experience like that of a platform-specific app.
