Safari Web App and iOS App

We understand that SF is the native font, and that symbols are part the overall look and feel of the Apple system, and that some symbols are reserved for specific features. With these constraints in mind, we do not wish to implement SF symbols in any way as to misrepresent Apple's existing products or features. Is it possible to use SF symbols in an iOS app and web app targeting Safari? It seems this would be relatively straight forward, and should be important to communicate design language properly across apps. Otherwise, there will be some confusion.
