Why do my PAGES have style and javascript?

This plugin is simple and I like simple. It places the sharing icons under my blog posts and not my pages — perfect. However, when I view the source of my pages, I see new javascript and style code. Why is this here since there are no icons? How can I prevent this? This is the code I don’t want:

<style type="text/css">div.simplesocial,a.simplesocial{float:left;display:block}a.simplesocial{margin-right:5px;width:32px;height:32px}a.simplesocial:hover{margin-top:-2px}</style>
<script language="javascript">function simplesocial(t,w,h){
window.open(t.href, 'simplesocial', 'scrollbars=1,menubar=0,width='+w+',height='+h+',resizable=1,toolbar=0,location=0,status=0,left='+(screen.width-w)/2+',top='+(screen.height-h)/3);
return false;}</script>
