Question 1

Is this random picker truly fair and unbiased?

Accepted Answer

Yes, absolutely. Our random picker uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same technology used by banks and security applications. Every participant has exactly equal chances in fair mode - no manipulation is possible.

Question 2

How does the randomness algorithm work?

Accepted Answer

We use your browser's built-in cryptographic random number generator (CSPRNG). Unlike simple Math.random(), this provides true randomness based on hardware entropy sources. The algorithm is deterministic once seeded, ensuring consistent and verifiable results. All calculations happen locally - nothing is sent to servers.

Question 3

Is my data safe? What do you store?

Accepted Answer

We store absolutely nothing on our servers. Your participant list is saved only in your browser's local storage for convenience - you can clear it anytime. No cookies track you, no analytics collect personal data, and no information leaves your device. The draw runs 100% client-side.

Question 4

Can I use this for Instagram or YouTube giveaways?

Accepted Answer

Yes! Our giveaway picker is perfect for social media contests. You can paste comments, usernames, or any list of participants. The visual wheel spin adds transparency - show your audience the live draw. Many influencers and streamers use our tool for fair, public winner selection.

Question 5

What's the difference between Fair and Custom draw modes?

Accepted Answer

Fair mode gives everyone equal chances - perfect for giveaways where fairness is essential. Custom mode lets you assign different weights/probabilities to participants - useful for loyalty programs, engagement rewards, or scenarios where some entries should have better odds. Both modes show transparent probability calculations.

Question 6

Can I pick multiple winners at once?

Accepted Answer

Yes! Set the number of winners before spinning. For multiple winners, we use our casino roulette visualization with numbered balls - each landing in a unique slot. Winners are selected without replacement, ensuring the same person can't win twice in a single draw.

Question 7

Does it work on mobile devices?

Accepted Answer

Absolutely. Our tool is fully responsive and optimized for all devices - phones, tablets, and desktops. The wheel animations are smooth, touch-friendly, and work identically across all platforms. No app download required - just open the website.

Question 8

Is this free? Are there hidden costs?

Accepted Answer

100% free with no hidden costs, no premium tiers, no signup required. We're supported by non-intrusive ads that never interrupt your draws. Use it unlimited times with unlimited participants.
