Hi I deleted all my notes from iCloud, there is one way to restore all of them?

Hello Cristal022.

Thanks for reaching out to Apple Support Communities. Check out the following steps to restore notes:

"Check your Recently Deleted folder

If you store your notes on iCloud, check your Recently Deleted folder:

1. Open Notes, then tap the back icon  until you see your Folders list.
2. Tap Recently Deleted and search for your note.

If you find your note in Recently Deleted or in another folder, you can move it:

1. In the Notes list, tap Edit.
2. Select the note that you want to move.
3. Tap Move, then select the folder you want to move it to.

If you use notes with another service, like Gmail or Yahoo, check the Trash folder of that account in the Mail app. If you delete a note from the Notes app, your third-party account will usually keep it in the Trash folder. To recover a note from the Trash folder, you need to copy and paste the note to a new note in the Notes app."

If you're missing notes on your iPhone, iPad, or iPod touch

Cheers.

Start by looking in "Deleted Notes"

Unfortunately, it is not possible to recover Notes after they have been removed from the "Deleted Notes" folder. Only option could be if you have an iCloud Backup from the time your Notes were on the phone.
