Just a thought while I am browsing, you could do something in your theme to set a conditional statement and give different css classes to a page.
Lets say you wanted to hide it, you could make a long conditional if statement saying if this page or this page or this page or this page give the css class name nopdf then in your css use
.nopdf .pdf24Plugin-cp {
display:none;
}
I did something similar to hide the link from my homepage.
Cheers
