Help with gamipress logs

Hello,

Please can you help confirm if this code are correct and safe to use

// Schedule event to clean gamipress logs every 7 days
if ( ! wp_next_scheduled( 'gamipress_clean_logs' ) ) {
    wp_schedule_event( time(), 'daily', 'gamipress_clean_logs' );
}

// Gamipress action to perform log cleaning
function gamipress_clean_logs_daily() {
    gamipress_clean_logs( 7 );
}
add_action( 'gamipress_clean_logs', 'gamipress_clean_logs_daily' );

And

// Schedule event to clean user earnings logs every 7 days
if ( ! wp_next_scheduled( 'gamipress_clean_user_earnings_logs' ) ) {
    wp_schedule_event( time(), 'daily', 'gamipress_clean_user_earnings_logs' );
}

// Action to perform user earnings log cleaning
function clean_gamipress_user_earnings_logs_daily() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'gamipress_user_earnings';
    $wpdb->query( "DELETE FROM $table_name WHERE date < DATE_SUB( NOW(), INTERVAL 7 DAY )" );
}
add_action( 'gamipress_clean_user_earnings_logs', 'clean_gamipress_user_earnings_logs_daily()' );

Thanks
