# About One Click Sprout

A small garden of free tools for chance: roll dice, flip coins, pick numbers, shuffle lists, get a yes or no, and draw playing cards.

## What it is for

Board games with a missing die, tabletop role-playing sessions, classroom name picks, giveaway draws, team splits for five-a-side, and settling who does the washing-up. Each tool has its own page with a short explanation of how to use it and what its options do.

## How it works

Everything runs in your browser. The tools take their randomness from crypto.getRandomValues, the browser's cryptographically secure random number generator, and turn it into fair results: rejection sampling so that no number or face is favoured, Fisher–Yates shuffles for lists and cards, and Floyd's sampling algorithm for picking numbers without repeats from very large ranges. The [random number generator](https://oneclicksprout.click/random-number-generator/) page explains the method in more detail.

There are no accounts and no ads. What you type into a tool stays on your device; the [privacy page](https://oneclicksprout.click/privacy/) lists the few settings the site remembers in your browser.

## Who runs it

One Click Sprout is an independent site, free to use, and not connected to any game publisher. It shares a footer with a handful of sister sites that offer other small browser tools. The site uses Cloudflare Web Analytics to count page views, without cookies and without ever receiving what you type into the tools.
