I get asked, but once I say no, I haven't gotten prompted again.

And if you accidentally click yes, it even has a section in the 'safety check' section that will have a list of sites sending you too many notifications.

Also, there's another setting where you can toggle between: ask permission, block all; and some other silent blocking them....

I wonder if it remembers my settings better because I have a google account that my chrome is logged into for syncing these things?
