Angularjs: How to keep checkbox value after reload

I got the following code from W3Schools, but am wondering how to get the checkbox value to persist even after reload:

Keep HTML: <input type="checkbox" ng-model="myVar">

<div ng-if="myVar">
<h1>Welcome</h1>
<p>Welcome to my home.</p>
<hr>
</div>

<p>The DIV element will be removed when the checkbox is not checked.</p>
<p>The DIV element will return, if you check the checkbox.</p>

Right now, if you check the box and reload the page, the checkbox becomes unchecked again. How would you get the checkbox to retain its value even after reload? Thanks!
