Acceptance of terms
By accessing or using How Much Water Do I Need (howmuchwaterdoineed.com), you agree to these Terms of Service. If you do not agree, please do not use the site. The site is operated by webuildstuff.io.
Not medical advice
The site and its calculator provide general educational information only and are not medical advice. Results are estimates based on published general guidance and do not account for your full medical history, medications, or conditions. Never use this site as a substitute for professional medical judgment, diagnosis, or treatment. Always consult a qualified healthcare provider before making changes that affect your health, including your fluid intake — especially if you have kidney, heart, or electrolyte conditions, are pregnant or breastfeeding, or care for an infant or young child. If you may be experiencing a medical emergency, seek immediate medical care.
Use of the service
The calculator and tracker are provided for personal, non-commercial use. You agree not to misuse the site, attempt to disrupt or overload it, scrape it in a way that degrades service for others, or use it in any manner that violates applicable law. The tracker stores your log data in your own browser; we are not able to back it up or restore it.
Advertising and third-party content
The site displays advertising, including ads served through Google AdSense, and may link to third-party websites or tools we find useful. We do not control and are not responsible for third-party ads, their content, or third-party sites and services. Interactions with advertisers (including any use of their websites or cookies) are solely between you and them. See our Privacy Policy for how advertising cookies are used.
No warranties
The site is provided "as is" and "as available" without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, and non-infringement. Hydration science evolves and calculator outputs may be incomplete, outdated, or wrong for your circumstances. We do not warrant that the site will be uninterrupted or error-free.
Limitation of liability
To the maximum extent permitted by law, webuildstuff.io and its operators will not be liable for any indirect, incidental, consequential, or punitive damages, or any loss of data, profits, or health outcomes, arising from or related to your use of — or inability to use — the site or reliance on its content, even if advised of the possibility of such damages.
Intellectual property
The site's name, design, text, and code are protected by intellectual property laws. You may share links to the site freely; any other reproduction or reuse of substantial parts of the site requires our permission.
Changes to these terms
We may revise these terms from time to time. The "last updated" date above shows the current version, and continued use of the site after changes take effect constitutes acceptance of the revised terms.
