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 visit counts use a cookie-free analytics service.

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

This site uses Cloudflare Web Analytics to count visits and see which pages are read. Cloudflare describes it as privacy-first: it does not use cookies or local storage, and it does not track visitors across sites. It reports aggregate figures such as pages visited, referring website, country, browser and device type.

The site has no other analytics, advertising or tracking scripts. Calculator inputs and results are never sent to analytics. Learn more in Cloudflare's Web Analytics information and Cloudflare's Privacy Policy.

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 or analytics cookies. The only item stored on your device is the theme preference above.

Third-Party Services

The website may rely on:

• A hosting provider — to deliver, secure, and monitor the website
• Cloudflare Web Analytics — cookie-free visit counts

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 or an extension if you prefer
• Clear 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.
