Privacy Policy

Last updated: March 2026

Your privacy matters — especially for a health-related site. This page explains exactly what data health.xaygo.com collects.

Health Data You Enter

All health calculations run entirely in your browser. Any data you enter — height, weight, age, body measurements, or pregnancy dates — is never transmitted to any server and is never stored anywhere. It exists only in your browser's memory while the page is open, and disappears when you navigate away or close the tab.

Analytics

We use Google Analytics (GA4) to understand aggregate site usage. This collects anonymized data such as pages visited, session duration, device type, and general geographic region. No personally identifiable or health-related information is included in analytics data.

You can opt out via the Google Analytics Opt-out Browser Add-on.

Advertising

This site may display advertisements via Google AdSense. Google may use cookies to show personalized ads based on your browsing history. You can manage ad preferences at Google Ads Settings.

Cookies

We use a single localStorage entry (health-xaygo-theme) to remember your dark/light theme preference. This contains no personal information and is never sent to a server.

Children's Privacy

This site is not directed at children under 13. We do not knowingly collect information from children.
