Privacy policy

Last updated: July 2026.

The short version

DoughMath is a static website with no accounts and no server-side processing. Every calculation happens locally in your browser. The ingredient amounts and settings you type are never sent to us or anyone else — they stay on your device.

What we store on your device

If you use the “Save” button on a calculator, or switch the light/dark theme, we keep that in your browser’s local storage so it is there next time. This never leaves your browser, we cannot read it, and you can clear it any time through your browser settings.

Analytics and advertising

At present DoughMath runs no analytics and shows no ads. If that changes in future, we may add privacy-respecting analytics and/or advertising (such as Google AdSense). If and when we do, those services may set cookies or use similar technologies, we will update this page, and where required we will ask for your consent through a banner before any such cookies are set. Third parties like Google may use cookies to serve ads based on prior visits; you can opt out via Google’s Ads Settings.

Your data never leaves your browser

Because the tools are entirely client-side, there is no database of your recipes, no email list you are added to without asking, and nothing for us to sell. That is a deliberate design choice, not a promise we have to police.
