Privacy Policy

Last updated: August 2026

What we collect

Nothing personally identifiable. The calculators run entirely in your browser; your flour, water and starter numbers never leave your device. We do not ask for accounts, emails, or logins, and we do not set our own cookies.

Local storage

The hydration calculator may remember your last entered values in your browser's local storage so your numbers are still there when you return. This data stays on your device and can be cleared at any time through your browser settings.

Advertising (Google AdSense)

This site plans to display ads served by Google AdSense. Google may use cookies (including the DoubleClick cookie) to serve ads based on your visits to this and other websites, and may use your IP address for ad delivery and fraud protection. You can learn how Google uses data when you use partner sites atpolicies.google.com/technologies/partner-sites, and manage or opt out of personalized advertising atadssettings.google.com.

Third-party links

Some pages may contain affiliate links to shops or books. If you buy through one of those links, the retailer's own privacy policy applies to that transaction; we may earn a small commission at no extra cost to you.

Your choices

• Clear cookies and local storage in your browser at any time.
• Opt out of personalized ads via Google Ads Settings.
• Use the site as-is; every tool works fully without accepting any cookies.
