Lisa has been using the Notepad app on her iPad, but the last few entries have disappeared.
Leo says that if Lisa has her iPad set up with iCloud, there's a chance that the notes have been backed up. She should go to Settings and tap "iCloud". If the Notes switch is set to on, then it's been backed up to iCloud. Although if she deleted the notes, then they would be deleted from iCloud too. If she hasn't set it to backup to iCloud, then chances are the notes are gone. She could backup her notes further by emailing the notes to herself.
Leo recommends using Evernote. It has a trashcan that she could recover notes from.
