Privacy Policy

Last updated: 19 July 2026

The short version

FitCalcly's calculators run entirely in your browser. The numbers you type into a calculator — your height, weight, age, and similar values — are never sent to our servers, stored, or shared. There are no accounts and no signup.

Information we collect

Like most websites, our hosting provider automatically records basic technical logs when you visit, such as your IP address, browser type, pages visited, and timestamps. These logs are used only for security and to keep the site running.

Cookies and third-party services

• Analytics: We may use a privacy-respecting analytics service to understand aggregate traffic (for example, which calculators are most used). This data is aggregated and does not identify you personally.
• Advertising: We may display advertising (such as Google AdSense) to keep the site free. Ad providers may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalised advertising at Google Ads Settings. When advertising is active, third-party vendors, including Google, use cookies to serve ads based on your visits to this and other sites.
• CDN & hosting: The site is served through a hosting provider and content delivery network, which process technical request data to deliver pages to you.

Children's privacy

FitCalcly is intended for adults and does not knowingly collect any personal information from children.

Your rights

Depending on your location, you may have rights to access, correct, or delete personal data held about you. Since we do not maintain user accounts or store the values you enter, in most cases there is no personal data for us to hold — but you can contact us with any privacy question.

Changes to this policy

We may update this policy as the site evolves (for example, when advertising or analytics are added). The date at the top of this page shows when it was last revised.
