Privacy Policy

Last updated: June 2026

This Privacy Policy explains how Calzeno (“we”, “us”) handles information when you use our website and calculators.

Calculations stay on your device

The values you enter into our calculators (such as weight, height, and age) are processed entirely in your browser to produce results. We do not transmit or store these inputs on our servers.

Analytics

We use Google Analytics to understand how visitors use the site in aggregate (for example, which pages are popular). This data is collected through cookies and similar technologies and helps us improve the site. It does not include the health figures you enter into the calculators.

Advertising

We display ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings.

Cookies

Cookies are small files stored on your device. We and our partners use them for analytics and advertising as described above. You can control or delete cookies through your browser settings; doing so may affect how some features work.

Your choices

Depending on your location, you may have rights to access, correct, or delete personal data and to object to certain processing. Because we do not store the inputs you enter, most personal data we hold is limited to aggregate analytics and advertising identifiers managed by the third parties named above.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the “last updated” date above.
