This seems like a misunderstanding of the tech. Service workers can really only fire up when they get a push notification, which you have to explicitly opt into, or when the page is running in the browser.
The processing allowed is tightly controlled, and even with permission the push notification can't do anything behind your back - it has to result in a visible notification which will alert you that there's something you want to disable.
