How to store tabs & checklist values in localstorage?

I've found an excellent to-do list on code @ http://ift.tt/2jzVBT4

function AddTabFromTemplate(newID) {
var domID = newID.replace(/ /g, '_');
$newTab = $('#template').clone();

However, any information entered will be lost on reload. Can someone help with the code needed to save tabs & checked checkboxes to localstorage? Thanks!
