Privacy Policy

Last updated:  06/11/2026

This Privacy Policy explains how Fat-Calculator.com ("we," "us," or "our") handles information when you use our website at https://fat-calculator.com (the "Service"). Fat-Calculator.com is an informational website offering free online calculators. We keep our data practices minimal: the tools are free, require no account, and are built to work without collecting personal information about you.

Calculator Inputs Are Not Stored

The values you type into our calculators are processed in your browser to produce a result. We do not send these inputs to our servers, we do not store them, and we cannot see them. When you close or reload the page, those values are gone.

Information We Do Not Collect

We do not require registration. The Service has no user accounts, logins, profiles, or comment system. We do not ask for your name, email address, or payment details to use any calculator, and we do not knowingly collect personal information from anyone.

Cookies and Local Storage

The Service may use a small number of functional cookies or browser local storage to remember your preferences — for example, your choice of metric or imperial units. These do not identify you personally. You can clear or block cookies at any time in your browser settings, and the calculators will continue to work.

Analytics

We may use a privacy-respecting analytics tool to understand aggregate, anonymous usage — such as which pages are most visited — so we can improve the site. This data is aggregated and does not identify individual users.

Advertising

We do not display third-party advertising."

Server Logs

As with most websites, our hosting provider may automatically record standard technical log data — such as IP address, browser type, and request time — for security and reliability. These logs are not used to profile individual visitors and are kept only as long as needed for operational and security purposes.

External Links

Our pages may link to external websites, including the open sources behind our formulas. We are not responsible for the privacy practices of those sites and encourage you to read their policies.

Children's Privacy

The Service is intended for a general audience and is not directed at children. We do not knowingly collect personal information from children.

Your Choices

Because we do not collect or store personal information about you through our calculators, there is generally no personal data for us to access, correct, or delete. If you have any questions, you can contact us using the details below.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page.
