Clean Master

About

Clean Master is a freemium, proprietary utility software originating from China, primarily known for its PC version (Windows) as a junk file cleaner and computer optimizer, though an Android version also exists. It enhances device performance by removing invalid, temporary, and cache files from over 500 applications, offering a comprehensive product portfolio that includes privacy cleaning, process killing, registry cleaning, history cleaning, file shredding, software uninstallers, and software management, with support for multiple languages. While some users commend its effectiveness, describing it as a program that 'works like a charm' and 'one of the best of its kind,' its market position is also marked by significant controversy; particularly, the Android version, following its acquisition by Cheetah Mobile, has faced severe criticism for allegedly containing trackers that send user data, including passwords, to their servers, alongside complaints about aggressive upselling of additional services. More information can be found on its website, https://www.cleanmasterofficial.com/en-us/, and it maintains a social media presence on platforms like Facebook.
