 <p>Assuming you've made sure your application doesn't persist anything, all you have left to do is add <code>UIApplicationExitsOnSuspend</code> and set it to true in your application's <code>Info.plist</code>. The moment the user leaves your application, its process will terminate. When the user starts your application again it won't remember anything; it'll just start from the beginning. This includes displaying the launch image.</p>
