How to disable progress bar

Hello,
One more request for help.
I wanted to disable the big bar on all pages and added a conditional tag
is_page()
But having such a tag – disables Cart and Checkout.
How to have a mini bar only on three sort of pages:
a product page under the “add to cart” button (I have it now),
a cart
a checkout pages
?
I checked all the required fields in the settings but I can see the bar on a Contact page (for example)!
Thanks.
