<p>All browsers have varying capacity levels for both localStorage and sessionStorage. Here is a <a class="external" href="http://dev-test.nemikor.com/web-storage/support-test/" title="http://dev-test.nemikor.com/web-storage/support-test/">detailed rundown of all the storage capacities for various browsers</a>.</p>

<div class="note">
<p><strong>Note: </strong>since iOS 5.1, Safari Mobile stores localStorage data in the cache folder, which is subject to occasional clean up, at the behest of the OS, typically if space is short.</p>
