How do I record data on my Chrome account's storage with only Javascript in Google Chrome?

We programmed our own statistical record pages in HTML and Javascript jQuery to record them on Chrome's local storage every time we change the numbers (like the following)

$('input[name="hoge"]').change(function(){
  localStorage.setItem("hoge", $(this).val())
})

However, I would like to view and change the same statistical records on another PC, and I would like to create the ability to store statistical records on storage linked to a Chrome account instead of local storage only with Javascript instead of using Chrome extensions.
If anyone knows how to do it, please let me know.
