How do I save a game?

i'm almost done with a video poker game...

I want to release an android and ios version.

but the problem arrived with the web version i want to release for other platforms.

while playing the web version whenever i refresh the browser or close it, the values reset. like the score comes down to the initial score.

How do i prevent that???

This link helped me learn how to create save and load features. Instead of web storage look for local storage as that is what it is called now.
