Remove footer from theme

Hi, I want to remove the footer from my website (www.little-robot.co.uk) which says
“Powered by WordPress · Theme by DinevThemes”

I have tried looking in the footer.php file but it doesn’t seem to be there. I’ll copy and paste the footer.php code below.

Any help is much appreciated.

Thanks

<?php
/**
* The template for displaying the footer.
* @package Squarex
*/
?>

</div><!– #content –>
</div><!–#wrap-content–>

<div class=”clearfix”></div>

<div class=”out-wrap site-footer”>

<footer id=”colophon” class=”wrap site-footer” role=”contentinfo”>

<?php if ( is_active_sidebar( ‘footer1’ ) || is_active_sidebar( ‘footer2’ ) || is_active_sidebar( ‘footer3’ ) ) { ?>

<div class=”grid3 clearfix”>

<?php dynamic_sidebar(‘footer1’); ?>
