What System Ninja is
System Ninja is a Windows system-optimization utility that removes junk files and unnecessary startup items. Its cleaner can target cookies, internet cache, session logs, thumbnail icons, and browsing history in supported browsers, including Chrome, Internet Explorer, Firefox, Edge, Opera, Brave, Yandex, PaleMoon, and more than 30 others. Cleaning begins with a heuristic scan and then checks known junk locations. CleanSync downloads new cleaning rules in the background; the maker says rules pass security measures before removing files. The software also includes a process manager, app uninstaller, duplicate-file finder, and software and hardware analysis tools. System Ninja supports Windows 7, 8, 10, and 11, while the product page specifically lists Windows 10 and 11 support. The free plan costs $0.00 per free. Pro Club Standard costs $14.95 a year for up to 10 devices, and Pro Club Extended costs $74.75 a year for more than 10 computers.
