Privacy Policy
What we collect, what we don't, and how third-party advertising cookies work on this site.
Last updated: 2026. Replace "Vitalis" and the placeholder domain with your real business name and domain before publishing.
What we collect
The calculators on this site (BMI, age, body fat, calories, and the rest) run entirely in your browser. The numbers you type in, such as your height, weight, or age, are never sent to our servers, stored in a database, or logged anywhere. Closing the tab clears them completely.
We do not require an account, an email address, or any other personal information to use the calculators.
Cookies and advertising
This site may show advertisements served by Google AdSense and other third-party advertising networks. These networks may use cookies, web beacons, and similar technologies to collect information about your visits to this and other websites, in order to provide advertisements about goods and services that may interest you.
Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and other sites on the internet. You can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising by visiting aboutads.info, or, if you're in the EU, youronlinechoices.eu.
We may also use standard, privacy-respecting analytics to understand overall traffic patterns (for example, which pages are visited most). Any such analytics data is aggregated and is not used to personally identify you.
Third-party links
This site may link to external resources or advertisers. We are not responsible for the privacy practices or content of external sites. We encourage you to review the privacy policy of any site you visit.
Children's privacy
This site is not directed at children under 13, and 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 address it.
Your choices
Because we don't collect or store personal data on our own servers, there is generally nothing for us to delete or export on request. For advertising cookies specifically, use the opt-out links above. Most browsers also let you block or delete cookies directly in their settings.
Changes to this policy
This policy may be updated from time to time to reflect changes in our practices or for legal reasons. Continued use of the site after changes are posted means you accept the updated policy.
