How do I save game to safe location?

If I use webstorage to save my game, then clear my browser cache, my saved game gets deleted.

Is there a better way to save games so clearing the browser cache will not delete my saved games?

Thanks

"WebStorage does not store in the browser cache."

it shouldnt be happen if you delete your cache, maybe you are:

"However if the user opts to clear all their cookies or offline website data, WebStorage will be cleared. "

And actually i dont know how you could save your game outside of the browser and i think if this could be possible a lot of webpages would save there data outside of the browser too and that would that a lot of disk space that would never be deleted.
