Calculation Logic

  • Picking: Generate uniform random indices using Web Crypto.
  • Shuffling: Apply Fisher–Yates swaps from end to start; randomness comes from crypto.getRandomValues().
  • Uniqueness: In no-duplicate mode, we draw from a shrinking pool to ensure unique winners.

FAQ

Is this random picker truly fair?

Yes. We use the browser’s crypto.getRandomValues() API instead of Math.random() for cryptographically secure randomness.

Can I pick multiple winners without duplicates?

Yes. Disable “Allow Duplicates” and the tool guarantees each winner is unique.

Is my data safe (local/privacy)?

Yes. Lists and results are processed locally with no uploads or server storage.

Is it free? Can it remember my list?

It’s free. Optional local storage can keep your list after refresh (you can clear it anytime).

Why not use Math.random()?

Math.random() isn’t designed for security or strong fairness. Web Crypto provides higher-quality, less predictable randomness.
