What are some easy, lightweight ways to write and save small quantities of data for a dirt simple web app?

I literally just need to save/write one number. I'm writing a counter app and I want to be able to save the value of the counter whenever I close the app. I have no plans to distribute this app so I'm perfectly fine with storing the data on my machine. I've learned a little bit of mongoDB but it's not lightweight enough for my purposes. Can I just read/write from a JSON file? Is there something better?

    You could save it into the Html5 localstorage.

    window.localStorage.setItem('counter', yourCounterVariable).

    And then retreive it using
