Terms and Conditions

By using HealthSand you agree to these terms. They are written plainly, and they exist to keep a free site sustainable and honest about its limits.

Use of the site

HealthSand's tools and guides are free for personal, non-commercial use. You may link to any page, share a result, and print a page for personal use. You may not copy substantial parts of the site's text or code and republish them as your own, scrape the site aggressively in a way that degrades it for others, or use the site for any unlawful purpose. Automated bulk copying of the whole site is not permitted.

Your responsibility

You are responsible for how you use the results. Check that your inputs are correct, treat estimates as estimates, and do not rely on a tool for decisions where safety depends on precision — sun exposure for children, activity in extreme heat, or any health decision for a person with a medical condition. Nothing on this site replaces professional advice, and you should seek it where it matters.

Availability

The site is provided "as is," without warranties of any kind. We aim for continuous availability and correct calculations, but we do not guarantee that the site will always be available, error-free, or complete, and we may change, suspend, or remove pages at any time without notice.

Liability

To the fullest extent permitted by law, HealthSand and its operators are not liable for any loss, injury, or damage arising from use of the site or reliance on its content, including estimates produced by the tools. This does not limit liability that cannot lawfully be limited.

Changes to these terms

We may update these terms from time to time; the version posted here is the current one. Continued use of the site after a change means you accept the updated terms. Questions about these terms can be sent to contact@healthsand.com.

Effective: October 2026.
