From the developer:
Prevent Windows sleep when your PC is in use. Streaming video, running extensive calculations, copying large amount of files, etc. Inputs might be idle, but sleep should not be triggered as the PC's resources are in use.
Usage patterns are also logged: you can check out how much your PC is used actively and how much time it spends in sleep, how much sleep time has been prevented.
