About Randomness
Our generator uses JavaScript's Math.random() function which provides pseudo-random numbers that are sufficient for most purposes. While not cryptographically secure (for which you'd need Web Crypto API), the numbers are:
- Uniformly distributed: Each number in the range has equal probability
- Unpredictable: No discernible pattern in generated numbers
- Statistically random: Passes basic tests for randomness
