The answer to this question is yes in numerous instances, and it is possible to recover deleted notes from iPhonedata. Apple stores would automatically remove the notes in the Recently Deleted folder, only to be easily reinstated within the retention period. All you have to do is open Notes, then go to the Recently Deleted folder, pick the notes you would like to have back, and drag them back. When the notes are backed up with iCloud, there is a possibility that they are still on other devices. Nevertheless, when notes have been deleted and erased permanently, and they are no longer available in the backups, then it would be hard to recover them; hence, it is important to enable backups frequently to avoid permanent loss.
