<h3>External services</h3>

What is the service and what is it used for? 
– The ImgSmaller API (https://imgsmaller.com) provides image compression and account information used by this plugin to optimize your Media Library and display plan/quota details.
What data is sent and when? 
– When you start compression, the plugin sends the public URL of each selected attachment (or a secure, tokenized proxy URL if the file is not publicly accessible) along with your API key to request compression. After polling completes, the plugin downloads the optimized image bytes. 
– When viewing plan info, the plugin requests your current plan usage and limits using your API key.
