Security You Can Trust

Fairness requires true unpredictability. Aynzo Tools uses the crypto.getRandomValues() API, which provides cryptographically strong random values. Importantly, everything happens in your browser—we never see your numbers or influence the results, making it the most trusted RNG for sensitive giveaways.
