How long is bar hidden for? and hide for logged in users

Hello

This plugin look great!

1- I see that it stops loading when user subscribes. but for how long? does it set a cookie? can we control that?

2- is this code correct to show only for guest

add_filter( ‘mctb_show_bar’, function( $show ) {
return !is_user_logged_in();
} );

thanks
