Notes app information accidentally deleted

Since the notes were deleted from the Original Poster’s iPhone as well as iPad, they are almost certainly housed in iCloud. Notes housed in iCloud are not saved on an iPhone backup. They don’t require saving there, because they’re saved in “Recently Deleted” for thirty days.

You’re welcome.

Here’s one other important tip - it certainly sounds from your original post like you are sharing your Apple ID with your daughter. Regardless of her age, you should stop doing that immediately. Then thoroughly cleanse her iPad.

What to do before you sell, give away, or trade in your iPhone, iPad, or iPod touch - Apple Support

Set up Family Sharing if you wish.

Family Sharing and Apple ID for your child - Apple Support

From a backup made when the notes were present. Be advised

that restoring such a backup will overwrite everything newer

on the iPhone.

Stop sharing an AppleID. Your daughter should have her own

to prevent such mishaps in the future.

Having deleted “Recently Deleted” in addition to your Notes folder means all your information is gone. She deleted not only your information, but its backup.

Thank you. I did not know that.

You’re welcome. Glad to help.
