Frequently asked questions

Are the numbers truly random?

Integers are produced with the Web Crypto API (crypto.getRandomValues), which is suitable for most non-cryptographic and many security-sensitive uses in the browser.

Why isn’t the result in the share URL?

Only min, max, and count are shared so links reproduce your settings—not a specific random draw.

What if min is greater than max?

The range is treated inclusively either way; min and max are swapped automatically.
