SDK Manager Updater

What process does the SDK manager use to check for updates? I haven’t started the SDK manager in a little bit and today the dialogue box popped up saying there is an update. I can’t find any service or cronjob related to this. Where is this periodic process stored and triggered?

I do not like unknown services and processes running without my say so, regardless of how trusted the vender is. There’s a reason I don’t use Windows.
