I am creating an app where at a certain point I want to ask the user for permission to use his location.

I am thinking about using the navigator.geolocation.getCurrentPosition to store the latitude and longitude of a user, obviously after he has accepted to.

I thought about storing this on local storage so that whenever the user opens the browser again he appears on that position.

However, I thought of the other case. What happens if he goes on Location and resets the permission, or decides not to share his location anymore. Is there any event or way I can see if he did that?

Because if he did that I need to delete those stored keys and values of lat and long from Local storage.

Thanks.
