title: Can a user manually clean chrome.storage.local in Chrome extensions
body: <p>I am building an extension that is heavily dependent on the local storage, and I want to be absolutely sure that a user will not clean it.</p>
  
  <p>I know that I can use <code>chrome.storage.local.clear()</code> to clear it, but is there any other way that the user can clean it manually?</p>
