Privacy Policy

Overview

Free Protein Calculator ("we", "us", "our") respects your privacy. This Privacy Policy explains what information may be processed when you use this website and how it is used.

The short version: Calculator inputs and results stay in your browser, we do not sell personal information, and optional production analytics is disabled unless it is explicitly configured.

Calculator Data

Calculator inputs and results are processed entirely in your browser using client-side JavaScript. We do not transmit calculator field values or results to our servers or intentionally send them to analytics services.

Analytics Data

We may enable Google Analytics on the production website to understand general website usage. The analytics script is not loaded in development or when production analytics has not been explicitly enabled and configured.

When Google Analytics is enabled, it may process information such as:

• Pages visited, page titles, and visit timing
• Referring website
• Browser, operating system, and device type
• Approximate location derived from an IP address
• Standard interaction data allowed by the Google Analytics property configuration

Our website configuration disables Google signals and advertising-personalization signals. We do not define analytics events that contain calculator inputs or results. Google Analytics may still use cookies or similar browser identifiers to distinguish visits and produce aggregated reports. Google processes analytics data under its own privacy terms.

Learn more in Google's Privacy Policy and Google's Analytics opt-out information.

Hosting and Technical Logs

Our hosting provider may process standard request information needed to deliver and protect the website, such as IP address, user agent, requested URL, timestamps, and error or security logs. Retention and handling of those logs are controlled by the hosting provider and our hosting configuration.

Cookies and Browser Storage

We use one localStorage entry to remember your light or dark theme preference. It stays in your browser and is not a cookie.

We do not use advertising cookies. If Google Analytics is enabled, it may set first-party analytics cookies or use similar browser storage as described above. You can block or clear those identifiers through your browser settings, a privacy extension, or Google's opt-out tool.

Third-Party Services

The website may rely on:

• A hosting provider — to deliver, secure, and monitor the website
• Google Analytics — only when production analytics is explicitly enabled

We do not use analytics data for advertising personalization or sell calculator data.

Your Choices

You can:

• Use the calculators without submitting their inputs or results to us
• Block analytics with browser privacy controls, an extension, or Google's opt-out tool
• Clear analytics cookies and the saved theme preference through your browser
• Contact us with questions about this policy

Children's Privacy

The primary protein calculator accepts ages 14 and above. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can investigate and delete it where applicable.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
