Privacy Policy

At HealthCalculator.io ("we," "us," or "our"), your privacy is our top priority. This Privacy Policy explains how we collect, use, and protect your information when you visit our website and use our free health and fitness calculators.

1. Information We Collect

We do not collect or store any data you enter into our calculators. All calculations happen locally in your browser — your inputs never leave your device.

We may collect limited non-personal information automatically, including:

• Usage Data & Analytics – We use Google Analytics to understand how visitors interact with our site (e.g., pages visited, time on site). This data is anonymised and does not identify you personally.
• Cookies & Local Storage – We use essential cookies to ensure the website functions properly. See our Cookie Policy for full details.

2. How We Use Your Information

Any information we collect is used solely to:

• Operate, maintain, and improve our website and calculators;
• Analyse usage trends to enhance user experience;
• Respond to enquiries submitted via our contact form or email.

3. Newsletter Subscriptions

We offer an optional "Notify Me" newsletter on our website. If you choose to subscribe:

• What we collect: Only your email address. Nothing else.
• How we use it: To send you updates about new calculators, health guides, and site improvements. We will never share, sell, or rent your email address to any third party.
• How to unsubscribe: Every newsletter email includes a one-click unsubscribe link at the bottom. You can also unsubscribe at any time by emailing partnerships@healthcalculator.io with "Unsubscribe" in the subject line, and we will remove you within 48 hours.
• Data retention: Your email address is held only while you remain subscribed. Once you unsubscribe, it is permanently deleted from our records.

4. Emails and Contact Information

If you contact us at partnerships@healthcalculator.io, we may retain your message and email address solely to respond to your enquiry. We will never use your email for marketing purposes without your explicit consent.

5. Third-Party Services

We use the following trusted third-party services:

• Google Analytics – to analyse website traffic. Google may collect visit data as described in Google's Privacy Policy. You can opt out via the Google Analytics Opt-out Browser Add-on.

These third parties have their own privacy policies, which we encourage you to review.

6. Data Security

We implement reasonable technical measures to protect our website from unauthorised access. However, no internet transmission is 100% secure, and you use our site at your own risk.

7. Children's Privacy

Our website is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal data to us, please contact us immediately so we can remove it.

8. Your Data Protection Rights

Depending on your location (e.g., EEA or California), you may have the right to access, rectify, erase, restrict, or port your personal data, or to object to its processing. To exercise any of these rights, contact us at partnerships@healthcalculator.io. We will respond within one month.

9. Changes to This Policy

We may update this Privacy Policy periodically. The latest version will always appear on this page with an updated date. Continued use of the site after changes constitutes acceptance of the revised policy.
