Frequently Asked Questions (FAQ)
Is my private information safe here?
Yes, absolutely! SuperUtility runs entirely inside your web browser. None of your passwords, files, or text inputs are ever sent to a server, saved online, or shared with anyone. Everything stays 100% private on your own device.
How are passwords and random keys generated?
We use highly secure, device-level random generation (using your browser's built-in cryptographic engine). This ensures that every password or unique key (UUID) you generate is completely random, fair, and virtually impossible to guess.
Can I use this app without an internet connection?
Yes! Once you open the website, the tools are saved directly in your browser. You can turn off your internet or Wi-Fi completely, and all the tools (like the password, QR, and hash generators) will still work perfectly offline.
Are the random picks and numbers truly fair?
Yes, they are 100% fair. We use advanced, balanced mathematical algorithms (like the Fisher-Yates shuffle) to make sure every random picker item or random number has an exactly equal chance of being chosen, with zero bias or repeating patterns.
