Privacy Policy

Last updated: August 2026

CalorLab ("we", "us", or "our") operates the website calorlab.com. This policy explains what data we collect, why, and the choices you have. Our core promise is simple: the measurements you enter into the calorie calculator never leave your device.

1. Data You Enter

Your age, gender, height, weight and activity level are used only by the JavaScript running on this page to produce your TDEE, calorie target, macros and weight projection. We do not send these inputs to any server, store them, sell them, or share them with third parties. All computation happens locally in your browser.

2. Cookies

We use cookies and similar technologies for two things: remembering your cookie preference and supporting third-party advertising. You can decline cookies using the banner shown on your first visit, or clear cookies through your browser at any time.

3. Third-Party Advertising

We may display ads served by third-party advertising networks such as Google AdSense. These partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising at any time by visiting Google Ads Settings or www.aboutads.info.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to websites, enabling them and their partners to serve relevant ads based on your visits to this site and/or other sites on the Internet.

4. Analytics and Log Data

Like most websites, our hosting provider may automatically collect standard server log information such as your IP address, browser type, pages visited, and the date and time of your visit. This is used to keep the service secure and to understand general traffic patterns. It is not linked to the health data you enter into the calculator.

5. Your Choices

6. Children's Privacy

Our site is a general-purpose tool and is not directed at children under 13. We do not knowingly collect personal information from children.

7. Changes to This Policy

We may update this policy from time to time. Any changes will be posted on this page with an updated "last updated" date.
