how do i recover deleted notes from the app notes.

Here's a description of the sequence: How to Restore Notes from a Time Machine Backup - The Mac Observer

If you don't have Time Machine backups or some other backups available, and if the data was not recently deleted, then the data is very likely gone.

If Time Machine backups are not already running and you wish to start: How to use Time Machine to back up or restore your Mac - Apple Support

If you haven't quit notes all you have to do is go to edit drop down and hit undo it will restore the note, it will work for all the notes you deleted, you just keep selecting undo. If you've quit notes then all you've got is Time Machine backups if you use time machine which is a good idea to do all the time anyway.

Sorry.....I have not backed up with Time Machine. I guess they are gone.

Most folks eventually lose data. Whether accidental deletions, corruptions, damage, hardware failures, theft, whatever, all storage and all computers will inevitably fail. Most of those folks that do lose data then start keeping backups.

The linked article does provide some other ways that might be able to recover the data.

That's ok we've all been there. Most of us never realize we're better off buying an external drive to use with Time Machine until we've lost something we really needed or wanted, it happened to me and even worse a drive I was using finally failed too because they don't last forever. My advice to everyone is to get some form of an external drive for that which you need to have. You don't need to reply, I'm just posting this for all to see.

If you have deleted the notes in the last 30 days, there should be a Recently Deleted folder in the Notes application.
