By accessing or using SnapWaterCalc, you agree to these Terms of Service. If you do not agree, please do not use the site.
SnapWaterCalc provides a free, browser-based hydration calculator offering general estimates based on SnapWaterCalc's own calculation model. No registration is required. Inputs are processed in your browser; preferences may be stored locally on your device, not on our servers.
Results reflect our chosen baseline and adjustment assumptions. They are not measured individual requirements or medical recommendations, and citing published hydration references does not validate this combined model. SnapWaterCalc does not provide medical advice. Always consult a qualified healthcare professional before making health decisions, especially if you are pregnant, ill, or taking medication.
The service is provided "as is" without warranties of any kind. SnapWaterCalc is not liable for damages arising from use of the calculator or reliance on its results.
