Frequently Asked Questions

Can I lose my data?
Since data is stored locally, clearing browser data or using a different device will not carry over your information.
Does this work offline?
Yes, once loaded, all functionality works entirely offline with no internet connection needed.
Is my data private?
Absolutely. Everything stays in your browser. No data is sent to any server or third party.
Can I generate truly random numbers?
This tool uses cryptographically secure randomness (Crypto.getRandomValues) when available for better quality random numbers than Math.random alone.
What is the maximum range?
You can set any range from -999,999,999 to 999,999,999. For ranges larger than 16 million, the tool uses Math.random as a fallback.
