Draft pending legal review. These terms describe how the site actually works, but they have not been reviewed by a lawyer and the operating entity’s details are not yet filled in. They must be reviewed and completed before the site is published publicly.

1. Using the site
You may use these calculators freely, for personal or commercial purposes, without an account. By using the site you accept these terms.
2. What a result is, and is not
Every calculator here is an information tool. A result is not professional advice of any kind — not medical, not financial, not legal, not engineering.
- Health calculators do not diagnose anything and do not replace a clinician. Several are explicitly estimates with published error ranges, and the pages say so.
- Finance calculators use the assumptions stated on the page. Real products carry fees, rate changes and terms that no general calculator can know about.
- Every calculator depends on what you enter. A correct formula applied to a wrong input gives a confident wrong answer.
Decisions with real consequences — a mortgage, a treatment, a structural load — should be taken with a qualified professional who can see your actual circumstances.
3. Accuracy
We take accuracy seriously: formulas are sourced, results are tested automatically, and errors are corrected when found. We do not warrant that the site is error-free, and to the extent the law allows we are not liable for loss arising from reliance on a result. If you find an error, tell us.
4. Accounts
If you create an account you are responsible for keeping your password to yourself and for what happens under your account. Tell us if you think it has been compromised. We may suspend an account used to attack the site, to send spam, or to break these terms.
5. Content and intellectual property
The text, design and code of this site belong to us or to our licensors. Formulas themselves are not ours — they belong to the bodies that publish them, and are cited on each page.
You may quote a result, and link to any page. You may not scrape the site wholesale, republish substantial parts of our written content as your own, or reproduce the calculators.
6. Acceptable use
Do not attempt to break, overload or gain unauthorised access to the site, upload anything malicious, or use the contact form to send bulk or unsolicited messages.
7. Third-party links and ads
We link to the sources behind our formulas and we display advertising. We do not control those third parties and are not responsible for their content or their practices.
8. Availability
The site is provided as it is. We do not promise it will always be available, and we may change or withdraw any calculator.
9. Changes to these terms
We may update these terms. The date at the top shows when. Continuing to use the site after a change means you accept it.
