How to recover my Notes

The possible options are...

• Check in your iCloud account: https://www.icloud.com
• Check your email accounts that you had but removed. Because many of the accounts have notes synced like Google, iCloud, AOL, Exchange, Outlook, Yahoo etc.

You can't find it in the recently deleted folder, then probably you have not deleted any Notes in last 30 days.

• You may have shared the Notes over AirDrop
• You may have sent the Notes via iMessage or email to someone

Do not restore from iCloud backup.

iCloud backup doesn’t include information already stored in iCloud, like Contacts, Calendars, Bookmarks, Mail, Notes, Voice Memos, shared photos, iCloud Photos, Health data, call history, and files you store in iCloud Drive
