Privacy Policy

Last updated: September 18, 2026

SourdoughCalc ("we", "us", or "our") operates the website sourdough-calc.com. This privacy policy explains how we collect, use, and protect information when you use our site.

Information We Collect

SourdoughCalc runs entirely in your browser. We do not require an account, and we do not collect, transmit, or store the ingredient weights, hydration percentages, or any other values you enter into the calculator. Any settings you adjust are kept locally in your browser (local storage) and never leave your device.

Cookies & Advertising

We display advertising served by Google AdSense. Google and its partners may use cookies (including the Google AdSense cookie) to serve ads based on your prior visits to this or other websites.

• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of third-party vendor cookies for personalized advertising at aboutads.info/choices.

For more information about how Google handles data, see policies.google.com/technologies/partner-sites.

Your Choices (GDPR & CCPA)

If you are in the European Economic Area, you have the right to access, correct, or erase personal data held about you, and to object to or restrict certain processing. If you are a California resident, you have the right to know what personal information is collected and to opt out of its sale — we do not sell personal information, and we do not knowingly collect personal data from the calculator itself.

Because the calculator runs client-side, we generally have no personal data to act on. For any privacy request, contact us at [email protected].

Local Storage

We use browser local storage solely to remember your calculator preferences (such as the last used calculation mode). This data stays on your device and is never transmitted to us. Clearing your browser data removes it.

Third-Party Services

• Google AdSense — advertising (see Cookies & Advertising above).
• Google Fonts — typography; requests to Google Fonts are covered by Google's privacy policy.

Children's Privacy

SourdoughCalc is not directed at children under 13, and we do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes are posted on this page with an updated date.
