pages not to be seen in navigation

I’m trying to create a page on my wordpress site, but not have it shown in the navigation. These methods don’t work, as the public isn’t able to view the page.

I’d like to make a link at the bottom of my home page that says “view privacy statement”, then link it to the page.

Any help would be great.
Thanks in advance!
