Bottom Corner Chat - Ability to exclude certain pages and/or posts

Some pages/subpages/categories are accessed by very specific visitors (i.e. only people with a link, not able to be navigated to). And these pages require very specific formatting and rules of what's allowed to be displayed. And a chat box in the bottom corner is not something that would be allowed. However, I want this chat thing. So, really, all I want is the ability to exclude certain pages (yes/no to affect child pages) and posts and categories.
I'm not sure how I feel if one of the excluded pages/posts/categories has it specifically enabled within the post (probably would lean toward allowing the override).
Thank you.
