If associated with an email account, check the Notes folder of that email account. If you don't see a Notes folder, go to Settings> Mail, Contacts and Calendars > Email address > toggle off Notes. Then go back to the email address and check the Notes folder.
I don't think it's a difficult thing to recover notes from iCloud. As long as you have backed up your iPhone to iCloud before, you can easily restore them from your iCloud backup files with some recovery tools like FonePaw iPhone Data Recovery, right? But if you have no valid backup files, you can also choose to recover deleted notes directly from iPhone.
You probably can. I was able to recover deleted notes. I had an iphone 4, i had my notes generated via the built in ios 7 notes app - auto backed up to icloud. ie I had the "notes" switch set to on under the icloud setting.
I accidentally deleted a very long note when using the notes app. Tried heaps of recovery programs that did not work. When you delete a note in the app, it is automatically deleted off icloud in seconds. I tested this.
Solution - I thought - hang on, Apple will never delete something permanently and immediately off its servers such as icloud. I contact Apple support and requested they restore any notes they could on my icloud account. Bingo - they did and most if not all of my missing notes were back and viewable on my phone. Bet this post is deleted coz big brother doesn't want you to know this and many other secrets about iphones and apple products.
A few things on your post. First, this site is all about Apple products, tips and tricks. We all love our Apple devices and some of us will defend them at all costs.
We also love finding out and sharing all the tips and tricks we can, as long as it’s nothing illegal or anything that falls under an NDA clause. The fact that Apple can and will restore files isn’t a trade secret.
As for your post getting deleted, I don’t see anything wrong with it, so as long as you don’t cross the lines that you agreed to when you signed up, you have nothing to worry about.
