How Spinnit tools work

Spinnit is built as a set of lightweight browser tools. You open a page, enter the options you need, and the result is generated on your device. This page explains what that means for randomness, privacy, fairness and sensible use.

Browser-first tools

The random number, name picker, wheel, dice, team picker and list tools run in your browser with JavaScript. Spinnit does not need an account, server database or uploaded file to produce a result. If you paste a class list, giveaway entries or names into a tool, the tool logic uses that text in the page you already have open.

Some site-level services, such as Google measurement or advertising scripts, may load separately as described in the Privacy Policy. Spinnit tool code is not designed to send your pasted lists, generated passwords or random results to Spinnit servers.

Randomness by tool type

Everyday random tools

Tools such as the random number generator, dice roller, coin flip, name picker and list shuffler use browser-based pseudo-randomness. That is appropriate for games, classrooms, informal draws and everyday choices.

Password generator

The password generator uses the browser Web Cryptography API through crypto.getRandomValues(), which is designed for stronger random values than ordinary game-style randomness.

Fairness depends on setup

A random tool can only choose fairly from the options it receives. Duplicate names, missing entries, unclear rules or changing the list after the draw can all make a result feel unfair.

When Spinnit is a good fit

Numbered draws

Pick from ticket numbers, spreadsheet rows, classroom seat numbers or custom numeric ranges.

Classroom turns

Pick students fairly, especially when no-repeat mode helps everyone get a turn before repeats.

Informal winners

Draw winners from a pasted list once your entry rules and duplicate handling are clear.

Strong passwords

Create unique passwords with secure browser randomness, then save them in a password manager.

When not to rely on it alone

Do not use everyday Spinnit random tools as the sole system for gambling, legal lotteries, financial decisions, medical decisions, security keys, official audits or any draw that requires certified randomness and independent oversight. For those situations, use the required official process. Spinnit is best for fast, transparent, low-stakes random choices.
