Hello, by using the Code profiler I discovered that your plugin is triggering everywhere - on every frontend and backend page, its adding around 0,15-25s on cloudways hosting which performs great and is almost as much Cpu time consuming as the woocommerce plugin.

Would you please consider conditioning of the plugin if it should trigger on every pageload and also maybe which could should be triggered? Telling stock status and quantity is not so highly cpu consuming I hope and also there is no point of doing it on contact page or in most wp-admin pages.
