I don't want my Notes saved to iCloud but see a scary sync warning

Hi and thank you!

On my iPhone 14, iOS 18:

Settings> iCloud> Notes. I don't want my Notes on iCloud. I want to turn off "Sync this iPhone" but the warning message says "all iCloud notes will be removed from your iPhone". I have only written these Notes on my iPhone, so will my messages be deleted from my iPhone?

When I open the Notes app, to the Folders page, under the iCloud heading, the Notes Folder has zero. Under the On My iPhone heading, The notes Folder has over 100+.

I really need confirmation that my "On My iPhone" notes won't be deleted if I "unsync" my iPhone Notes from iCloud.

Thanks for your time!
