Frequently Asked Questions

Are these calculators medically reviewed?

Our health calculators use standard clinical formulas (like Hamwi for ideal weight). While accurate, they are screening tools and not a replacement for professional medical advice.

Can I use these tools offline?

Yes. Most calculators run purely in your browser and will function perfectly even without an internet connection once loaded.

Is my data saved on your servers?

No. All inputs and calculations are processed locally on your device. We do not store or transmit your personal data.
