Cookie question

So I have a simple web site with w/o logins and server side stuff. Someone goes to one of the calculators and enters values. Those values are used in calculations and an area of the page displays the results.

So the second a visitor leaves everything is gone (reset). Is there a simple way I can push a cookie to their computer with the values they have entered?

I’m hoping that I can set it up so when they come back the page will auto populate with the last set of values they used.

An example of the calculation page can be found here

PS. I’m hoping that someone will point me to a big button I just press and it all happens, maybe in Wappler 1.5 if not available yet
