Terms of Use

Last updated: September 21, 2026

These Terms of Use ("Terms") govern your use of the Speed of Aging mobile application and the biopsychometric.com website (together, the "Service"), operated by Biopsychometric Limited, a New Zealand company (company number 9360200) ("we," "us," or "our"). You accept these Terms when you tap Agree in the app, and by using the Service. If you do not agree, please do not use the Service.

1. Important medical disclaimer

The Service is for general informational and educational purposes only. It does not diagnose, prevent, monitor or treat any disease or condition, it is not a medical device, and it does not provide medical advice.

The assessments and risk estimates provided by the Service — including the Speed of Aging (biological aging) score, the stroke risk estimate, and the cardiovascular disease risk estimate — are based on published population-level statistical models. They describe how a group of people with similar characteristics tends to fare on average; they cannot tell you what will happen to you as an individual.

Always seek the advice of a qualified physician or other health professional with any questions about a medical condition, your health, or before making any decision related to your health. Never disregard professional medical advice, or delay seeking it, because of something you have read or seen in the Service. If you think you may have a medical emergency, call your doctor or emergency services immediately.

The Service is intended for adults aged 18 and over.

2. About the risk estimates

The risk assessments are re-implemented from published, peer-reviewed science and are provided with attribution:

These models have known limitations. They were derived from specific populations and age ranges, they rely on the accuracy of the information you enter, and they do not account for every factor that affects your health. Where you provide an age below the range a model was validated for, the Service will tell you and will base the estimate on the youngest validated age; such estimates are especially approximate. Results should be interpreted with a health professional.

3. Your account and eligibility

You can use the Service without an account. If you want your results saved and kept in your history, you can create an account with Sign in with Apple on iPhone, with Google on Android, or with either one on the website, and agree in the app to us storing your health information. How we handle that information is set out in our Privacy Policy.

You are responsible for the information you provide and for the security of the device you are signed in on. Inaccurate inputs produce inaccurate results. You must be at least 18 years old to use the Service.

4. Price

The Service is currently free to use. If we introduce paid features in future, we will describe what they cost before you buy anything. Any purchase would be sold and processed through Apple's App Store or Google Play and subject to their terms, and we would not receive or store your card details.

5. Acceptable use

You agree not to misuse the Service, including by attempting to interfere with its normal operation, reverse-engineer it, access it by unauthorized means, or use it in any way that is unlawful or that could harm us or other users.

6. Intellectual property

The Service, including its design, text, and software, is owned by us or our licensors and is protected by intellectual property laws. The underlying scientific equations are the work of their respective authors, cited above. We grant you a limited, personal, non-transferable licence to use the Service for your own personal, non-commercial purposes.

7. No warranty

The Service is provided "as is" and "as available," without warranties of any kind, whether express or implied, including as to accuracy, reliability, fitness for a particular purpose, or that the Service will be uninterrupted or error-free.

Your consumer rights are not affected. Nothing in these Terms limits any right you have under the New Zealand Consumer Guarantees Act 1993 or the Fair Trading Act 1986, or under any other law that cannot be excluded. If you use the Service in Australia, nothing in these Terms excludes, restricts or modifies the consumer guarantees under the Australian Consumer Law.

8. Limitation of liability

To the fullest extent permitted by law, and subject to clause 7, we will not be liable for any indirect, incidental, special, or consequential loss, or for any decision made or action taken in reliance on the Service or its results. Your use of the Service and any reliance on its assessments is at your own risk.

9. Changes to the Service and these Terms

We may modify or discontinue the Service, or update these Terms, from time to time. We will post the updated Terms on this page with a new "Last updated" date. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

10. Where the Service is offered, and governing law

The Service is currently offered in New Zealand. These Terms are governed by the laws of New Zealand, and you submit to the non-exclusive jurisdiction of the New Zealand courts. If you use the Service from another country, you are responsible for complying with the laws that apply to you there.
