The author has demonstrated that she does not know the Mac OS. Since the early days of OSX the Mac OS has included built-in maintenance scripts that run automatically so you don't have run useless third-part solutions. They do all that stuff that the author claims her program does.
Admittedly, long ago those scripts ran ONLY if the computer were turned on and not sleeping--not very realistic for the wee hours of the morning when the scripts are programmed to run. Many of us ran third-party apps to manually run the scripts. But that is now ancient history.
Starting with OS 10.5 Leopard, introduced in Oct 2007, the scripts were redesigned to wake the computer if necessary and do a "catch-up" run if the computer had been shut down at the appointed run times. No longer do you need any apps that claim to clean, disinfect, fumigate, tune up, polish the gronkulator, or find your Mac a mate. In addition to being useless, they interfere with your Mac's built-in protection and can slow the computer.
Why pay money for something your Mac already does?
