About Us

Built for everyone who cares about their health.

SuperBMI Calculator is a free, privacy-first health platform that puts accurate body health insights in the hands of anyone — no login, no ads, no data harvesting.

Our Mission

Health information should be accessible, accurate, and private. Millions of people search for a "BMI calculator" every day — and most tools give them a single number with no context, surrounded by ads, and often requiring account sign-ups that harvest personal data.

We built SuperBMI to be different. Our mission is simple: give you the most complete, accurate, and genuinely useful BMI and health tracking experience on the web — entirely for free, with your data never leaving your own device.

What Makes Us Different

Multi-Standard Engine

CDC, NHS (ethnicity-adjusted), and WebMD (body-frame) standards — not just one formula.

Zero Data Collection

Everything runs in your browser. No servers, no accounts, no tracking of any kind.

Family Profiles

Track up to 5 family members — from children to seniors — with full history.

Holistic Health Score

BMI is just one metric. We combine sleep, hydration, exercise, and mood for the full picture.

Built for the World

Available in 14 languages with localised nutrition guides for 6 major regions.

Free Forever

No premium tier, no paywall, no "pro" features. Everything is free for everyone.

Our Commitment to Privacy

We believe your health data is among the most sensitive information you own. SuperBMI is built on a strict zero-server architecture: all calculations, logs, profiles, badges, and challenge progress are stored exclusively in your browser's localStorage. There is no database, no analytics pipeline, and no third-party data broker involved.

We use Google Translate (opt-in, via the language selector) and Google Fonts — these are the only external services loaded on the site. We have no advertising partners and will never sell or share your data.

Medical Disclaimer

SuperBMI Calculator provides general health and educational information only. It is not a substitute for professional medical advice, diagnosis, or treatment. BMI is a screening tool, not a diagnostic instrument. Always consult a qualified healthcare professional before making health decisions based on your BMI or any other metric provided by this tool.
