Frequently asked questions
Are the numbers really random?
They come from crypto.getRandomValues(), your device's cryptographically secure generator, with rejection sampling so every number in the range is exactly equally likely — fair enough for raffles and draws.
Are the results recorded anywhere?
No. Numbers are generated on your device and vanish when you leave the page — take a screenshot if you need proof of a draw.
