How to use

You can either use the NoPrint Macro inline in your page:

{noprint} 
    Your rich text goes here
{/noprint}

or click on "Insert more content" button ( + ) in the toolbar and select NoPrint

What does it do?

The NoPrint Macro for Confluence Cloud excludes wrapped content from being exported as PDF.
This can be useful if you have private notes for your agents that should not be exported when a customer requests a PDF
