Overview

Your privacy matters. Our BMI tool runs entirely in your browser. We don’t collect or store your height, weight, or other calculator inputs.

What data we process

Calculator inputs (height, weight, age, sex, activity) are used only in-memory in your browser to compute results. They are not transmitted to us.

Cookies & analytics

We may use lightweight, privacy‑respecting analytics to understand general traffic patterns (page views, device types). We do not collect personally identifiable information through analytics. You can opt out using common tracking blockers.

Advertising

If we enable advertising in the future, ad partners may use cookies to measure performance. We will update this page with links to their opt‑out pages and controls.

Data retention

Because calculator inputs never reach our servers, we have nothing to retain from your calculations. Any analytics data, if enabled, is stored only in aggregate form for limited periods to evaluate site performance.

Your choices

Use content blockers to disable analytics or tracking scripts.

Do not enter information into forms you do not wish to share.

Children’s privacy

This site is for general audiences. If you are a parent or guardian and believe a child provided us with personal information, please contact us and we will promptly address it.

Data Minimization: What We Collect vs. What We Avoid

We built BMI Health Hub to work without requiring you to create an account. The calculator can be used without submitting personal health data to us. In general, we avoid collecting sensitive information such as medical history, diagnoses, or detailed biometrics beyond what’s needed to perform a calculation in your browser.

Like most websites, basic server logs may record anonymous technical details (for example, timestamps or requested pages) to help keep the site running and prevent abuse. If we ever add optional features that store preferences, we’ll describe exactly what is stored, why, and how you can remove it.

Cookies, Ads, and Third Parties

If advertising is enabled, third‑party vendors may use cookies or similar technologies to serve ads and measure performance. These tools may infer interests from browsing behavior across sites. You can manage cookies in your browser settings and review ad personalization controls provided by your device or ad providers.

Policy reviewed: January 8, 2026.

Privacy details in plain English

We built this site to be useful without collecting personal data. The BMI calculations and most interactions run locally in your browser, which means the numbers you enter are processed on your device.

What we may collect (and why)

What we don’t want

We do not ask for your weight history, medical records, or identity to use the calculator. If we ever add optional features that store data, they will be clearly labeled and opt‑in.

Data minimization: what it means here

“Data minimization” means we only use what’s necessary to run the site and improve it. For visitors, that translates to:

If you ever see a feature that asks for personal information, it should be optional and clearly explained. If it isn’t, let us know via the contact page.

How to browse health tools more privately

If you’re privacy-conscious, here are practical tips when using any online health calculator:

On BMI Health Hub, the calculator is designed to work without sign-up. If you ever see a feature that requests sensitive info, it should be clearly optional and explained.

Ad personalization and your options

If we display ads, they may be contextual (based on the page topic) or personalized depending on your settings and region. You can typically control ad personalization through your browser settings and your Google ad settings.

Practical privacy controls

We aim to keep the site useful even if you browse privately or block tracking.

Cookies and local storage: what’s the difference?

Some sites use cookies; others store small preferences in your browser’s local storage. Both can remember settings, but they work differently.

Our goal is to keep the site usable even if you clear cookies or block tracking. If we store preferences in the future, they will be limited and clearly explained.

Privacy Q&A

Do I need to create an account?

No. The calculator is designed to work without accounts so you can get value without sharing identity.

Is my BMI stored?

In general, BMI calculations are intended to run in your browser. If you clear your browser data, saved preferences may be removed depending on your settings.

What if I want maximum privacy?

Use a private window, avoid saving autofill, and clear site data after use. The site should remain usable even with stricter privacy settings.

Privacy checklist for shared devices

Our goal is to keep this calculator useful with minimal data. If you ever see a request for sensitive details, it should be clearly optional and explained.

Kids and teens

BMI interpretation is different for children and teens because growth and development change body composition. Many BMI tools online are designed for adults.

This site focuses on general adult BMI education and habit guidance.
