Privacy Policy

What this site is

Health Calculators (healthcalchub.co) is a free tool site. All calculators run entirely in your browser. No account is required, and no data you enter into a calculator is sent to our servers.

Data we collect

Calculator inputs: Health metrics you enter (weight, height, age, activity level, etc.) are processed locally in your browser using JavaScript. They are never transmitted to us or stored anywhere outside your browser session. Closing or refreshing the page clears them.

Email address: We do not have a sign-up form or email capture on this site. If you contact us directly via email, we keep that correspondence but do not add you to any mailing list without your explicit consent.

Standard server logs: Our hosting provider (Vercel) automatically records request logs — the pages visited, timestamps, browser type, and IP address. These logs are used for security monitoring and performance analysis. They are not sold or shared with third parties.

Cookies and tracking

We do not use tracking cookies, advertising cookies, or analytics cookies that follow you across the web. Vercel may set a technical cookie for routing purposes. No third-party ad networks are active on this site at this time. If we add advertising (e.g., Ezoic) in the future, this policy will be updated before that happens.

Sensitive health data

Health and body metrics you enter are processed entirely client-side and never leave your device. We have no access to your BMI, weight, sleep data, or any other health information you calculate with these tools.

Third-party services

• Vercel— hosting and CDN. Processes request logs as described above. Vercel's privacy policy is at vercel.com/legal/privacy-policy.
• Digital Dashboard Hub — this site is part of the Digital Dashboard Hub network. Clicking links to app.digitaldashboardhub.com takes you to a separate site with its own privacy policy.

Children

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

Your rights

Because we do not collect personal data beyond server logs, there is nothing to access, correct, or delete. If you have a question about a specific piece of information, email us and we will respond within 30 days.

California Privacy Rights (CCPA)

If you are a California resident, you have the right to know what personal information is collected, whether it is sold, to access it, and to request deletion. We do not sell your personal information. To exercise any right, email andrewjgaber@gmail.com with "CCPA Request" in the subject line.
