Privacy Policy

1. Information We Collect

We may collect information about you in a variety of ways. The information we may collect includes:

• Contact Data: If you contact us by email, we collect your email address and the contents of your message. We do not operate a newsletter or mailing list.
• Calculator Data: The physical metrics you enter into our calculators (age, weight, height, sex, activity level) are processed entirely inside your browser. This data is never transmitted to or stored on our servers.
• Derivative Data: Our hosting and analytics infrastructure may automatically collect standard server-log data such as your IP address, browser type, operating system, and pages visited. This data is used in aggregate form only.
• Cookies and Tracking Technologies: We use cookies for consent management and anonymous usage analytics. You may control cookie preferences via the cookie consent banner on first visit.

2. How We Use Your Information

We use the limited information we collect to:

• Deliver the calculator services and results you request, processed locally in your browser.
• Respond to your comments, questions, and support requests sent by email.
• Monitor and analyse aggregate usage trends to improve the website experience and calculator accuracy.
• Comply with legal obligations and resolve any disputes that may arise.

3. How We Protect Your Information

All health metrics you enter into our calculators are computed locally within your web browser. Your personal physical data is never transmitted to or stored on our servers — this is an architectural guarantee, not just a policy statement.

For any contact data we receive by email, we apply standard administrative and technical security measures. No method of data transmission or storage is completely impenetrable, and we cannot guarantee absolute security.

4. Disclosure of Your Information

We do not sell your personal data. We may share information in the following limited circumstances:

• Legal Compliance: If required by law, court order, or to protect the rights, property, and safety of users or the public.
• Business Transfers: In the event of a merger, acquisition, or sale of assets, user data may be transferred as part of that transaction.

5. Third-Party Links and Affiliate Referrals

This site contains curated referral links to external resources and partner services (such as Amazon, ClickBank, and BetterHelp via the Impact network). When you click these links, the relevant third-party affiliate network may deploy separate tracking cookies in your browser to verify traffic origin and attribute any resulting commission. We do not share your browser-calculated health metrics with these networks. Any information you submit to external third parties is governed exclusively by their own privacy policies.
