The tools on UtilityBase are intended for general, everyday use. Results depend on your browser, operating system, and hardware, and may not be perfectly accurate in every environment.

Hardware tests (such as the refresh rate test, dead pixel test, and microphone test) are diagnostic aids, not certified measurements. They can help you spot problems, but a passing result doesn't guarantee a device is fault-free, and a failing result is worth confirming with the manufacturer's own diagnostics before making warranty or purchase decisions.

Calculators are provided for convenience and general information only. They are not professional, financial, medical, or legal advice. Double-check any calculation that matters.

Generated values such as passwords and random numbers are produced with your browser's cryptographic APIs, but you are responsible for how you store and use them.
