In the footer of your php file you have this:

eval('print_output("' . fetch_template('T4U_privacy') . '");');

But in the header you have this:

$globaltemplates = array(
    'privacy',
);

Please make sure it is either one or the other.

Cache the right template, and name it correctly.

Important tip of a plugin release for the public: take your time to write it, test it, read through it, and get help during development.
