SpinTheWheel.buzz is an open, ad-free decision studio engineered with Web Crypto API (CSPRNG) for mathematical fairness and 100% client-side zero-retention privacy (COPPA/FERPA safe). In contrast, Wheel of Names is a legacy classroom name picker with extensive visual customization but serves programmatic ad banners, cookie trackers, and relies on traditional pseudorandom algorithms.

1. Cryptographic Randomness vs Standard Math.random()
When conducting a high-stakes classroom lottery, prize giveaway, or team assignment, true mathematical fairness is paramount. Standard JavaScript Math.random() relies on pseudorandom number generators (PRNG) like Xoroshiro128+, which can exhibit periodic clustering patterns when executed across rapid successive iterations.
SpinTheWheel.buzz integrates the browser's hardware entropy pool via window.crypto.getRandomValues(new Uint32Array(1)). This guarantees non-deterministic, cryptographically secure randomness (CSPRNG) with uniform probability across every single wedge, regardless of wheel size.
const array = new Uint32Array(1);
window.crypto.getRandomValues(array);
const normalizedRandom = array[0] / (0xFFFFFFFF + 1);
2. Student Data Privacy (COPPA & FERPA Compliance)
Teachers frequently paste sensitive student rosters, full names, and group pairings into online random pickers. Under the Children's Online Privacy Protection Act (COPPA) and Family Educational Rights and Privacy Act (FERPA), transmitting student personally identifiable information (PII) to unverified third-party servers poses serious compliance risks.
SpinTheWheel operates strictly on a zero-retention client-side model. Your lists are stored only in your local browser's localStorage. No names are sent across any network socket, ensuring full compliance for K-12 schools, universities, and enterprise HR departments.
3. Ad-Free Smartboard and Classroom Presentation
Displaying an ad-supported website on a classroom projector or Zoom screen share can inadvertently expose students or colleagues to inappropriate algorithmic banner ads, video overlays, or distracting popups.
SpinTheWheel features a clean, high-contrast dark studio interface designed specifically for large smartboards (Promethean, SMART Board) and live streaming displays with instant 1-click Fullscreen toggle.

Frequently Asked Questions
How is SpinTheWheel mathematically different from Wheel of Names?
SpinTheWheel implements browser-level Web Crypto API (crypto.getRandomValues) cryptographically secure pseudorandom number generators (CSPRNG), providing uniform distribution and non-deterministic entropy, whereas traditional tools rely on basic Math.random() pseudorandom implementations.
Is SpinTheWheel completely free of banner ads and popups?
Yes. SpinTheWheel is built with a zero-ad policy specifically designed for distraction-free classroom teaching on interactive smartboards and professional live streaming.
Is student roster data stored on remote servers?
No. All participant names and custom wheel slices are processed 100% client-side in your local browser memory (LocalStorage). No student records or personal data are ever uploaded or transmitted across the network.
Can I share custom wheels without creating an account?
Yes! SpinTheWheel serializes all your custom choices and themes directly into a shareable URL hash or link query, letting colleagues and students open the exact same wheel instantly without registration.
