Delete shared notes on iCloud.com

Go to icloud.com/notes, then sign in to your Apple Account (if necessary).
Select the shared note that you want to delete.
If you’re on a phone or tablet and you don’t see your notes, make sure the notes list is open.
Select in the Notes toolbar, then select OK.
One of the following happens:
- If you’re the owner: The note is removed from the devices of everyone you shared it with. You can recover recently deleted notes from your Recently Deleted folder.
- If you’re a participant: The note is removed from your notes list, but not the owner’s notes list or any other participant’s notes list. The note doesn’t move to your Recently Deleted folder. You can open and edit the note again by selecting the original link that the owner shared, unless the owner stopped sharing the note.
