Privacy Policy
Last Updated & Effective: January 1, 2026
1. Introduction
At BMI Calculator Free (accessible at https://bmicalculatorfree.online), we prioritize user privacy. This Privacy Policy outlines what information is collected when you visit our website, how that information is utilized, and the steps we take to protect your browsing experience.
By using our website, you signify your acceptance of this policy. If you do not agree with these terms, please discontinue use of the site.
2. Calculator Data & Client-Side Execution
Your health numbers remain on your device: When you input your height and weight into our BMI calculators, the calculations are executed entirely in your local web browser via JavaScript.
We do not transmit, log, record, or store your height, weight, BMI scores, or demographic inputs on our servers or in any external database. We do not require users to create an account, register, or provide personal identity credentials to calculate their BMI.
3. Information We Collect Automatically
Like most standard websites, when you navigate through our site, our hosting servers (such as Vercel or cloud delivery networks) automatically capture standard server access log records. This may include:
- Internet Protocol (IP) addresses (frequently anonymized)
- Browser type and operating system version
- Referring / exit pages and date/time stamps
- Requested URLs and server response codes
These logs are used exclusively for security analysis, preventing denial of service attacks, identifying broken links, and optimizing website performance. Server logs are not linked to personally identifiable health information.
4. Cookies and Web Beacons
BMI Calculator Free may use standard browser cookies to improve your user experience (such as remembering your selected unit system preference). You can choose to disable cookies through your individual browser options. Disabling cookies will not break the core calculator functionality.
5. Third-Party Advertising & Google AdSense Disclosure
Third-party vendors, including Google, may serve advertisements on our website in designated advertising areas.
- Google’s use of advertising cookies enables it and its partners to serve ads to users based on their visits to our sites and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings.
- Alternatively, users can opt out of a third-party vendor’s use of cookies for personalized advertising by visiting www.aboutads.info.
6. Third-Party Links
Our website may contain hyperlinks to reputable external websites (such as the CDC or WHO) for educational reference. We have no control over the privacy practices or content of these external domains and encourage you to review their respective privacy documentation.
7. Children’s Online Privacy Protection (COPPA)
We do not knowingly collect any personally identifiable information from children under the age of 13. If you believe your child has submitted personal information on our site, please contact us immediately so we can promptly delete such records.
