Terms & disclaimer

Not medical advice

WaterDailyGoal provides general wellness estimates for healthy adults. It is not medical advice, diagnosis, or treatment, and it is not a substitute for the judgement of a qualified healthcare professional. Always consult your doctor, midwife, dietitian, or pharmacist about your own hydration — especially if you are pregnant or breastfeeding, are caring for a child or older adult, take medication, or have a heart, kidney, or liver condition. If you ever feel unwell, seek medical care rather than relying on a calculator.

Estimates, not prescriptions

The numbers here are educational estimates based on widely published general guidance (see our methodology and sources). Real fluid needs vary from person to person and day to day with heat, activity, illness, altitude, and diet. Treat any figure as a starting point to discuss with a professional, not a fixed target.

No warranty

WaterDailyGoalis provided “as is”, without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. To the fullest extent permitted by law, we accept no liability for any loss or harm arising from use of, or reliance on, this site. You use it at your own discretion and risk.

Privacy

The calculator runs entirely in your browser. We do not require an account, and the numbers you enter are never sent to us or stored on a server.

To understand how the site is used, we use Google Analytics, which sets cookies and collects anonymised, aggregated data such as the pages you visit, your approximate location, and your device and browser. We use this only to improve the site, and it is never linked to the figures you enter in the calculator. You can opt out site-wide with the Google Analytics opt-out add-on. See the about page for the principles behind the project.
