Privacy

FermentCalc is designed to collect as little as possible. This page explains exactly what happens to data when you use the site.

What stays on your device

Calculator inputs and preferences (such as your unit system and last calculation) are saved in your browser's localStorage so the tools remember your settings. This data never leaves your device, has no account attached to it, and disappears if you clear your browser storage. Each calculator keeps its last inputs under an fc.* key, for example fc.units and fc.brine.v1.

What we do not do

• No accounts and no signups.
• No form submissions; calculator inputs are never uploaded.

Third-party services

This site may use third-party services, such as analytics to measure aggregate traffic and advertising partners to serve ads. Those services may set cookies or similar technologies on your device. You can manage advertising cookies through your Google Ads Settings and opt out of participating vendors at aboutads.info.
