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.
• Email Subscription Data: If you voluntarily subscribe through a signup form or pop-up on our site, we collect your email address so we can send you the free resource you requested (such as our printable tracker) and periodic newsletter and marketing emails. Subscription is optional, uses confirmed (double) opt-in, and you can unsubscribe at any time.
• 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. Our email signup forms use Google reCAPTCHA to prevent spam (subject to Google's Privacy Policy and Terms of Service), and our signup pop-up sets a cookie to remember whether it has already been shown to you. 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.
• Send you the free resource you requested and, if you subscribed, periodic newsletter and marketing emails — which you can opt out of at any time via the unsubscribe link in every email.
• 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. The only personal information we store is your email address, and only if you choose to subscribe.

For any contact data or subscriber email addresses we hold, we apply standard administrative and technical security measures and rely on reputable service providers. 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:

• Email Service Provider: We use MailerLite to manage our subscriber list and deliver emails. If you subscribe, your email address is stored and processed on MailerLite's servers in accordance with their own privacy policy.
• Spam Prevention: Our signup forms use Google reCAPTCHA, which processes limited technical data to distinguish humans from automated bots, in accordance with Google's privacy policy.
• 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. Your Email Choices and Privacy Rights

If you subscribe to our emails, you remain in control of your data:

• Consent: We only email you after you actively subscribe and confirm your address (double opt-in).
• Unsubscribe: Every email includes a one-click unsubscribe link. You can opt out at any time and we will stop sending you marketing emails promptly.
• Access, correction and deletion: You may request a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it entirely, by emailing [email protected].
• Regional rights: Depending on where you live (for example under the GDPR or CCPA), you may have additional rights, including the right to object to processing or to lodge a complaint with your local data protection authority.
• Retention: We keep your email address only for as long as you remain subscribed. If you unsubscribe or request deletion, we remove it from our active list.

6. Third-Party Links and Affiliate Referrals

This site may contain links to external resources and affiliate partner services. When you click these links, the relevant third-party 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 or your email address with these networks. Any information you submit to external third parties is governed exclusively by their own privacy policies.
