Privacy Policy


This Privacy Policy applies to the treatment of information provided to Orion Health when website users visit the site and use the Models.

What information does Orion Health collect?

Personal information

Orion Health temporarily processes information submitted by website users for calculation purposes only. Website users do not need to create a personal login to use the Models, and are restricted in the Terms of Use from entering personally-identifiable information when using the Models. It is therefore not expected that information submitted by users will identify them, or any other individual.

User activity data

Orion Health uses Google Analytics to track website user activity, including for example the webpages visited, the links clicked and the page view count. Your web browser automatically sends this information to Google. Google may also set cookies on your browser or read cookies that are already there. You can turn off Google Analytics tracking by installing the Opt-Out Browser Add-on here. Other than your IP address, no information that identifies you is available to Google or Orion Health. Your IP address is a number that can be used to uniquely identify your specific computer or other network device on the internet and can be used to find out information about your general location.

How will Orion Health use the information it collects about me?

When you visit this website and use any of the Models available to you, the information entered into the Models is processed by software installed in the Amazon Web Services (AWS) cloud, hosted in a data centre managed by AWS in Sydney, Australia. The software is programmed to use the information you enter, to predict outcomes based upon scientific research. Information about the scientific research behind Model outcomes is available on the website.

Orion Health uses the information it tracks via Google Analytics to understand how and from where the website is being used and to improve it. This information may be shared with third party Model contributors. You can read about how Google uses this information (and find the Opt-Out Browser) here.

How we protect your information

To prevent unauthorised use, maintain data accuracy, and ensure the appropriate use of information, we have put in place appropriate physical, electronic, and administrative procedures to safeguard and secure the information we receive.

How long will Orion Health keep my information?

Neither the information entered into the Models, nor the outcome inferred by the software, are stored by Orion Health following the calculation, except to the extent such information is captured in audit logs. Audit logs provide a record of the calculations made using the Models and will be securely maintained for a reasonable period of time following the relevant calculation. Audit logs do not identify website users.

Your Rights

To the extent we hold any personal information about you (e.g. your IP address), you have the right to ask us to correct or stop using it at any time. If you wish to exercise these rights, you can contact Orion Health at privacy@orionhealth.com.
