Terms of Use
Last updated 8 September 2026
By using IVF Due Date Calculator you agree to these terms. If you do not agree with them, please do not use the site.
What this site is
This site provides a free, informational due date calculator and supporting explanatory content. It is a reference tool. It is not a medical device, not a clinical decision aid, and not a substitute for care from a qualified healthcare professional.
No medical advice and no clinical relationship
Nothing on this site is medical advice, and using it does not create a doctor–patient or any other professional relationship between you and this site or its authors. Always seek the advice of your fertility clinic, obstetrician, midwife or another qualified provider with any question about your pregnancy or treatment. The full position is set out in the medical disclaimer.
Accuracy and limitations
The dates produced are estimates derived from standard obstetric convention. They may differ from the dates your clinic gives you, and your clinic’s dates should be treated as authoritative. We take care to keep the content correct, but we make no warranty that it is complete, current or free from error.
Acceptable use
You may use the calculator freely for personal and clinical reference. You may not attempt to disrupt the site, gain unauthorised access to it, or scrape it at a volume that degrades the service for other people.
Intellectual property
The text, design and code on this site are protected by copyright. You are welcome to quote short passages with attribution and a link. Republishing a page wholesale, or reproducing the calculator, is not permitted without permission.
External links
Where this site links to another site, that link is not an endorsement, and we are not responsible for the content or the practices of sites we do not control.
Limitation of liability
To the fullest extent permitted by law, this site and its authors are not liable for any loss or damage arising from your use of, or reliance on, this site or the dates it produces. The site is provided on an as-is and as-available basis, without warranties of any kind.
Governing law
These terms are governed by the laws of New Zealand, and any dispute relating to them is subject to the exclusive jurisdiction of the New Zealand courts.
Changes
These terms may be updated from time to time. Continuing to use the site after a change means you accept the revised terms.
