Anti-cheat software in either testing or gaming as well as employee productivity monitoring software (which is similar) generally has wide ranging permissions to do its job. So without doing research to confirm, I’d assume it has full access to everything you do across all applications, including when it’s not running in the foreground if it has background services running.

Personally, I never install that stuff on my primary operating system. I either use a dedicated device, dual boot, or if it is less sophisticated, use a virtual machine with only Windows and the necessary software. Of course I don’t use Windows for any personal computers anyway, too inefficient, and these days, too unstable and too much spyware built-in. I only use Windows on my work laptop these days which spys on me constantly to the point of crashing a lot as it collects all of its info when I use development software at the same time as WebEx or other necessary software.

If you want to know details, you need to look at the software they had you install as well as the dependencies it might install.
