Frequently Asked Questions

Find answers to common questions about using our tool, its features, and how it handles your data privacy.

We use the Web Crypto API (crypto.getRandomValues()) which provides cryptographically strong random numbers suitable for security applications. This is far superior to simple algorithms like JavaScript's Math.random(). While technically "pseudorandom" (generated by algorithms), the randomness is sufficient for all practical purposes including cryptography, gambling, and scientific research.
Absolutely! Many people use random number generators for lottery picks. Set your range (e.g., 1-49 for most lotteries), choose how many numbers you need (typically 6), enable "No Duplicates," and generate. Remember: lottery numbers are completely random, so generated numbers have the same odds as any other combination—there's no strategy that improves your chances.
You can generate numbers from -9,999,999,999 to +9,999,999,999 (negative 10 billion to positive 10 billion). This covers virtually any practical use case from dice rolls (1-6) to large statistical sampling. The tool maintains full randomness across the entire range.
No, true random number generation is non-repeatable by design—that's what makes it random! Each generation is independent and unpredictable. If you need reproducible "random" numbers (for scientific simulations, testing), you'd need a "seeded" random number generator which uses an initial seed value to generate predictable sequences.
Yes, completely free for unlimited personal and commercial use. Use it for business raffles, games, statistical analysis, random sampling, or any other purpose. No attribution required, no licensing fees, no restrictions on usage.
