I advise great caution when using a tool like this, especially if you have any sensitive information on your computer - especially crypto wallets. Since you can buy a license for only a few $ (at least for Windows OS), I don't see why anyone would risk running a tool that might activate your product, but who knows what else it can do.
Guys and girls, be smart, the security of your computer is worth more than $20 - be careful what you install.
