Demo footer remove

Hi. After importing the demo, I was hoping to build some of my site off of the page templates already created for me. However, I am not sure on how to remove the bottom footer or bottom part of the page where it says : “Experience something completely different. The most powerful theme ever. Buy Today!”. Can you please tell me where I can remove this off of the page and where I can modify it as well? I don’t want that bottom part on all of my pages. Instead, I want to edit the modify the details inside and have it on some specific pages instead. Thanks!
