Privacy Policy

1. Information We Collect

Calculator inputs: The values you enter into our calculators (weight, height, age, etc.) are processed entirely in your browser and are never transmitted to our servers. We do not store any personal health data.

Email addresses: If you voluntarily enter your email address in our optional email capture form, that address is collected and stored with our email service provider (ConvertKit) to send you the requested content. You can unsubscribe at any time.

Usage data: We use analytics tools that may collect anonymized data about how you use the site, including pages visited and time spent. This data does not personally identify you.

2. Cookies

We use cookies for analytics and advertising purposes. Our site may use Google Analytics and Google AdSense, which set cookies to help measure traffic and serve relevant advertisements. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

3. Advertising

FitnessCalc may display advertisements served by Google AdSense or similar advertising networks. These services may use cookies and web beacons to serve ads based on your prior visits to this and other websites. You may opt out of personalized advertising by visiting Google Ads Settings.

4. Affiliate Links

This site may contain affiliate links to products on Amazon.com and other supplement retailers. If you click an affiliate link and make a purchase, we may earn a commission at no additional cost to you. We only recommend products we believe are genuinely useful.

5. Data Security

Since calculator inputs are processed client-side and never sent to our servers, there is no risk of your health data being exposed through a server-side breach. Email addresses are stored with industry-standard encryption by our third-party email service provider.

7. Your Rights

You have the right to access, correct, or delete any personal data we hold about you (your email address, if provided). To exercise these rights, contact us. We will respond to all requests within 30 days.

8. Changes to This Policy

We may update this privacy policy from time to time. We will update the "Last updated" date at the top of this page when we make changes. Continued use of the site after changes constitutes acceptance of the updated policy.
