Yes, NyxoGuard is 100% free with no hidden charges, premium versions, or subscriptions. We built this software as a passion project to provide a genuine, ad-free alternative to the deceptive PC optimizers that currently dominate the market. You get full access to all deep-cleaning and optimization features without ever reaching for your credit card.

Absolutely not. NyxoGuard is designed by developers who actively fight against bloatware. We respect your privacy and never install external software, bundle third-party toolbars, or track your data. The software operates entirely offline, ensuring that your personal files and browsing history remain strictly on your hard drive.

When you launch NyxoGuard, it performs a tiny, secure HTTP request to our servers (`NyxoGuard.pages.dev`) to check if a new version exists. This is done by reading a simple text file. If a newer version is found, you will be prompted to download it. This process runs silently in the background and consumes zero CPU resources, ensuring your PC is never slowed down by background update services.

NyxoGuard uses native, safe Windows Win32 APIs to clean caches and temporary files. Unlike aggressive registry cleaners that blindly delete keys and cause system crashes, NyxoGuard specifically targets known junk paths left behind by uninstalled software. It has been meticulously tested across multiple versions of Windows 10 and Windows 11 to ensure absolute system stability is never compromised.

Most modern applications are built using heavy web technologies like Electron, which require loading an entire web browser into your RAM just to display the user interface. NyxoGuard is written purely in our advanced engine. This low-level programming language allows our software to communicate directly with your processor and storage drive, resulting in millisecond launch times and ultra-fast scanning speeds.
