About BodyMath
Free, science-based health calculators that respect your privacy.
Our Mission
BodyMath exists to make evidence-based health information accessible to everyone. We believe that understanding your body's biology—from caffeine metabolism to circadian rhythms—should be simple, free, and private.
Too many health tools collect your personal data or hide behind paywalls. We built BodyMath to be different: all calculations happen locally in your browser, your data never leaves your device, and everything is completely free.
What We Do
We create interactive calculators that translate complex scientific research into practical, actionable insights. Whether you're optimizing your sleep schedule, tracking caffeine's effects, or understanding your circadian rhythm, our tools provide personalized estimates based on peer-reviewed research.
Science-Backed
Every calculator is based on published research and established medical knowledge.
Privacy-First
Client-side processing means your health data stays on your device, always.
Easy to Use
Complex biology made simple with intuitive interfaces and clear explanations.
Always Free
No subscriptions, no paywalls, no hidden costs. Health tools should be accessible to all.
Our Approach
We're committed to transparency and scientific rigor:
- Evidence-based: All formulas are derived from peer-reviewed research published in reputable scientific journals.
- Transparent methodology: We document our sources and explain the science behind each calculator on our Methodology page.
- Clear limitations: We're honest about what our calculators can and cannot do. They provide estimates, not diagnoses.
- Continuous improvement: We regularly review new research and update our calculators to reflect the latest scientific understanding.
Who We Built This For
BodyMath is for anyone curious about optimizing their health:
- Sleep optimizers who want to understand how caffeine and alcohol affect their rest
- Shift workers managing circadian rhythm disruptions
- Health enthusiasts tracking wellness metrics and making data-driven decisions
- Students and professionals optimizing energy levels throughout the day
- Anyone interested in understanding their body's biology better
Why Privacy Matters
Your health data is deeply personal. Unlike many health apps and websites, we don't collect, store, or transmit any information you enter into our calculators.
How do we do this? All calculations happen entirely in your web browser using JavaScript. When you enter your weight, caffeine consumption, or sleep schedule, that data stays on your device. It's never sent to our servers because we don't have servers collecting user data.
We also don't use tracking pixels, analytics services, or advertising networks. Your privacy isn't a feature—it's fundamental to how we built BodyMath. Learn more on our Privacy Policy page.
Our Background
BodyMath was created by developers and health enthusiasts passionate about making scientific knowledge accessible. Our team combines backgrounds in software development, data science, and a deep interest in sleep optimization and wellness research.
While we're not medical professionals, we work diligently to ensure our calculators are based on solid scientific research. We consult published studies, clinical guidelines, and established health organizations to build accurate, helpful tools.
Not Medical Advice
It's important to understand what BodyMath is and isn't. Our calculators are educational tools that provide general estimates based on population averages and scientific research.
They are not medical devices, diagnostic tools, or substitutes for professional healthcare advice. Individual biology varies significantly, and only qualified healthcare providers can give personalized medical guidance. Always consult with your doctor or other qualified health professional for medical decisions.
