## What you type stays on your device

Every calculator on Blue Fizz Club runs in your browser. Temperatures, pressures, recipes, prices, guest numbers and menu titles are never sent to a server. Copied text and printed menu cards are made on your device.

## What is stored in your browser

Only one thing: if you pick a light or dark theme, that choice is kept in local storage under the name `bluefizzclub-theme`, so the next page opens in the same colours. Choosing "Auto" removes it. The calculators themselves store nothing; reloading a page starts again from the example.

Local storage stays in this browser on this device. Clearing your browser's site data removes it.

## Analytics

The site uses Cloudflare Web Analytics, which counts page views without cookies or cross-site tracking and never receives what you type into the tools. Blue Fizz Club does not use cookies, advertising, or any analytics of its own.

## Links to other sites

Pages link to official sources, to sister sites and to two other free tools, CleanTempMail and WebTraceCheck. Those sites have their own privacy policies.
