WordPress.org

Though Old it works great. Hides the tags from the widgets and the posts. Hides the tag itself not the post.
4 out of 5 because I had to make a modification to an annoyance.
The tags were also hidden from the admin area, to fix this add

if(is_admin())
        return $terms;

under

if ( $user_ID && get_option('hidden_tags_visibility','admin') == 'admin' ) {
        // Logged in - show all terms
        return $terms;
    }

other than that works perfectly
