About Spin the Wheel

Spin the Wheel is a small, free browser tool built and maintained by an independent developer who makes single-purpose web utilities. There is no company behind it, no growth team, and no sales funnel — just a wheel that picks names fairly and a few pages explaining how to use it well.

Fairness principles

• Equal slices, equal odds. Every entry occupies an identical slice, and the winner is drawn with a uniform random pick — 1 in n for n entries. The spinning animation is a reveal, not a physics simulation; it cannot alter the outcome.
• No hidden weighting. The only way to bias the wheel is to add duplicate lines, and those extra slices are visible to everyone watching.
• Honest limitations. The randomness comes from your browser’s standard generator (Math.random). That is entirely adequate for picking names, classroom turns, and giveaway winners, but it is not a certified or cryptographic RNG — we say so plainly rather than pretending otherwise, and we don’t recommend the tool for regulated gambling.
• Tested logic. The picking, sharing, and color logic is covered by an automated test suite, including a 10,000-spin distribution sanity check.

Data principles

• Your entries never reach us. The wheel runs entirely in your browser. Names are kept in your browser’s local storage and, when you copy a share link, inside the link’s # fragment — which browsers do not send to web servers. We operate no database and have no accounts.
• No sign-up, ever. Every feature works without registration, and that is a permanent design decision, not a trial.
• Transparent funding. The site may show ads to cover hosting. Details are in the privacy policy.
