Privacy Policy

Last updated: September 26, 2026

Biopsychometric Limited (New Zealand company number 9360200) operates the Speed of Aging mobile application, the website version of it at biopsychometric.com/app, and the biopsychometric.com website (together, the "Service"). We are the agency responsible for your personal information under the Privacy Act 2020. This policy explains what we collect, why we collect it, and what you can do about it.

The app is currently offered in New Zealand.

1. Your agreement comes first

You can use the app without an account. If you are not signed in, your answers and results stay on your phone — or, in the website version, in your web browser — and are never sent to us.

Your information reaches us only if you sign in and agree, in the app, to us storing it. We ask once, before your first result is saved, and we record the date and the version of this policy you agreed to.

You can withdraw that agreement at any time by deleting your account on the Profile screen. That removes everything we hold about you.

2. What we collect

Account information. When you sign in — with Apple on iPhone, Google on Android, or either one on the website — we receive the account identifier they give us, and the name and email address you choose to share. We never see your Apple or Google password. If you use Apple's Hide My Email, we only ever see the relay address Apple creates for us.

Health information you enter. Depending on which assessment you take, this may include:

• Profile details — age, sex, ethnicity, height, and weight
• Measurements — resting heart rate, systolic blood pressure, waist circumference, breath-hold duration, and reaction time
• Cholesterol information — your total-to-HDL cholesterol ratio, for the cardiovascular assessment
• Lifestyle factors — smoking, alcohol consumption, and physical activity
• Medical history — conditions such as diabetes, atrial fibrillation, existing heart disease, and family history of heart disease
• Medications — for example blood-pressure-lowering, cholesterol-lowering, or blood-thinning medication
• An optional neighbourhood socioeconomic indicator, used by the cardiovascular assessment

This is health information, and some of it is sensitive. We collect only the fields the assessment you chose actually needs.

Your results. The scores and risk estimates calculated from what you entered — your Speed of Aging score, your estimated stroke risk, and your estimated cardiovascular risk — and the history of those results over time.

Technical information. When the app opens, it checks for updates through Expo, which receives your device type, the app version, a random installation identifier, and your device's internet (IP) address. Our server keeps a short-term record of requests made to it, which shows which account made a request but not the answers you entered. The website version of the app does not check for updates. Like the rest of this website, it is served by Cloudflare, which receives your internet (IP) address and browser details when a page loads. Nothing is loaded from Apple or Google unless you choose to sign in on the website. When you do, their sign-in buttons are loaded from their servers, so they receive the same technical details, and if you are already signed in to Google in that browser, Google can tell that your Google account opened the sign-in option even if you don't go on to use it. We use no analytics, tracking, or advertising software of any kind, in the app or on this website.

Purchases. The app is free. If we add paid features later, purchases would be handled by Apple, Google and RevenueCat, and we would never receive or store your card details.

3. Why we use it

• To calculate, show and store your results, and to show you how they change over time
• To create and run your account
• To keep the Service working, and to find and fix faults
• To improve how the app calculates results. The scoring compares you against published population figures, and we use measurements from people who use the app — with names, email addresses and account identifiers removed — to check and improve those comparisons
• To reply when you contact us at info@biopsychometric.com

We do not use your information for scientific research, and we do not publish it. If we ever want to, we will ask you separately first, and you will be free to say no. We never sell your personal information, and we never use health information for advertising.

4. Who else holds your information

These providers hold your information only in order to provide their service to us. Each is required to protect it and not to use it for their own purposes.

• Apple and Google — handle signing in
• Neon — the database where your account and results are stored, in Sydney, Australia
• Render — the server that runs the app's backend, in Singapore. Render's network, run by Cloudflare, carries what the app sends to our server
• Expo — delivers app updates, and receives the technical information described above
• Cloudflare — hosts this website and the website version of the app, and receives the technical information described above
• RevenueCat — would handle subscriptions if we add paid features

Sending information overseas. Your account and results are stored in Australia and processed in Singapore. Before information goes overseas we check that the provider is required, by its agreement with us, to protect it to a standard comparable to the Privacy Act 2020.

5. How long we keep it

We keep your account and results for as long as your account exists.

When you delete your account, your information is removed from our live database straight away. Copies inside our database provider's automatic backups are overwritten on a rolling basis and are gone within 30 days. Our server's records of requests are kept for no more than 30 days.

If an account goes unused for two years, we delete it and the results in it.

6. Your rights

Under the Privacy Act 2020 you can:

• Ask for a copy of the information we hold about you. We will respond within 20 working days.
• Ask us to correct it if it is wrong. If we disagree, you can ask us to attach a statement of the correction you sought.
• Delete everything, yourself, on the Profile screen in the app. You can also email us and we will do it within 30 days.
• Withdraw your agreement to us storing your health information, by deleting your account.

Write to info@biopsychometric.com for any of these. If you are not satisfied with how we handle it, you can complain to the Office of the Privacy Commissioner at privacy.org.nz or on 0800 803 909.

7. Keeping it safe

Information is encrypted while travelling between the app and our server, and it is encrypted at rest by our database provider. Signing in is handled by Apple and Google, so we hold no passwords. The key that keeps you signed in is stored in your phone's secure keychain, or, on the website, in your browser's storage for this site, until you sign out. We take reasonable steps to protect your information, but no system is completely secure.

If a breach happens that could cause you serious harm, we will tell you and the Office of the Privacy Commissioner as soon as we can.

8. The copy on your own phone or computer

Every assessment you complete is also saved on your phone — or, in the website version, in that web browser — whether or not you are signed in, so that your results are not lost. That copy is under your control. The app can export your assessments as a spreadsheet (CSV) file, which includes your individual reaction-time measurements and your device model — once you share or save that file, it is outside our control. Deleting your account removes what we hold, but not the copy on your phone; deleting the app removes that. In a web browser, clearing this website's stored data removes it.

9. Children

The Service is for adults. Every assessment refuses an age under 18, and we do not knowingly collect information from anyone under 18. If you believe someone under 18 has given us information, contact us and we will remove it.

10. Changes to this policy

We may update this policy. The date at the top always shows the current version. If a change affects how we use health information, we will tell you in the app and ask for your agreement again before it applies to you.
