Your data stays on your device
Every calculator on Calcelo runs entirely inside your web browser. The numbers you enter — weight, height, measurements, dates — are used only to show your result on your screen. Nothing you type is uploaded to us, stored, or shared. We never see it.
What we collect
No account is needed. We may use privacy-friendly analytics to count page views so we know which calculators are useful. This never includes the health details you enter.
Advertising
To keep Calcelo free, we may display ads from third-party networks. These may use cookies to show relevant ads; you can manage cookies in your browser settings. This section will be updated when ads are enabled.
Medical disclaimer
Calcelo provides general estimates for educational purposes only. It is not medical advice. Always consult a qualified healthcare professional before making decisions about your health, diet, or exercise.
