Frequently asked questions
How random are the numbers?
They come from crypto.getRandomValues(), the browser's cryptographically secure source — suitable for draws, games and sampling, unlike Math.random().
Can I avoid repeats?
Yes. Pick a range and count, tick 'No repeats' to sample without replacement, and optionally sort the results.
Is anything sent to a server?
No. Numbers are generated entirely on your device.
