FAQ

Frequently Asked Questions

Yes. We use the Web Crypto API (crypto.getRandomValues) when available, which provides cryptographically secure random numbers. This is the same source of randomness used by security applications and is far superior to Math.random().
No. Utility Tools runs entirely in your browser. All history and preferences are stored in your browser's localStorage and never leave your device. We have no server, no database, and no analytics.
Once the page is loaded, all tools work without an internet connection. There are no server calls, external APIs, or CDN dependencies. You can even save the pages locally for fully offline use.
Absolutely. The random tools are perfect for picking raffle winners, randomizing student groups, choosing board game turn order, settling debates, and any situation where you need a fair random outcome. The results are unbiased and unpredictable.
Yes! A native iOS app is available on the App Store with additional features like 3D dice physics powered by SceneKit. This web version offers the same core functionality and works on any device with a browser.
