How to remove Footer Links?

How do remove the these links on the bottom of my site and replace them with my own links, such as Privacy Policy, About, Terms, etc.

Since I'm using a template, the guy says if I remove the links my site might not work. So, what do I do? Is there an easy way to copy this template and create it my own? Or can I get around this problem?

P.S. My site's template is in php and I have only limited knowledge of html.
