Privacy Policy

Who operates this website

Sourdough Calculator is maintained by its independent site owner. For privacy questions or requests, email 719171130@qq.com.

Calculator inputs

The recipe calculator processes loaf quantities, dough weights and ingredient ratios locally in your browser. The calculator does not upload these inputs, save recipes to a server, or store them in cookies or browser local storage. Reloading the page resets the form to its defaults.

Analytics and cookies

This version of Sourdough Calculator does not include Google Analytics, advertising pixels or third-party tracking scripts. The website’s calculator code does not set cookies. If analytics are added, we will update this policy to describe the provider, data collected, purpose, retention and any cookie choices before enabling them.

Hosting and access data

When you visit, the hosting infrastructure receives technical request information needed to deliver the website, such as your IP address, requested URL, browser information and request time. Hosting providers may retain access or security logs under their own policies. These technical requests are separate from the calculator inputs, which remain in your browser.

Email correspondence

If you email us, we receive your email address and the information in your message. We use this information to respond to your request, investigate an issue or manage the correspondence. Our email provider processes messages as part of delivering email.

Third-party services

The published pages include their styles, calculator code and illustrations directly in the HTML. They do not request fonts, images or analytics from external content providers. Hosting and email services still process the technical data needed to provide their services.

Retention and sharing

There is no server-side recipe database. We keep email correspondence only as long as reasonably needed to handle the matter, maintain relevant records or meet applicable obligations. Hosting log retention is controlled by the hosting provider. We do not sell your personal information. Information may be processed by service providers or disclosed when required by law.

Your choices

You can use the calculator without sending us an email or creating a calculator account. Contact us to ask about, correct or request deletion of information you have sent directly to us. Rights that apply to your information depend on your location and applicable law.

Policy updates

Changes to our data practices will be reflected on this page with an updated date. Please contact us if any part of this policy needs clarification.
