Last updated: 24 October 2026

Information We Collect

Symptom and Health Information

When you use our symptom checker, we may collect:

  • Symptoms you report
  • Answers to health-related questions
  • Demographic answers, such as age group and gender
  • Optional details about allergies, medicines and health conditions

Technical Information

Requests to our site include technical information such as your IP address, browser request headers and the requested address. Our advice endpoint uses an IP-based, in-memory rate limit. Hosting services may also process request and security logs; their retention is separate from the checker answers held in your browser.

Cookies and Analytics

We use Google Analytics to count page views. It receives the page path only (no query string, page title or full referrer), and Google signals and ad personalisation are turned off. It does not record symptom selections or answers. It may set cookies to tell visits apart. This is separate from hosting analytics and advertising services.

Your theme preference is stored locally in your browser.

  • Advertising cookies set by our advertising partner and the ad networks it works with, used to select ads, limit how often you see the same ad, and measure ad performance

How We Use Your Information

The symptom checker uses your selected symptoms, health answers and optional details to request general guidance. Contact-form details are used to receive and respond to your message. Technical request data supports service delivery and rate limiting.

AI Processing

When you request guidance, your answers are submitted to our server. The server includes symptom descriptions, health answers and relevant optional details in a prompt sent to the configured AI provider. The service can use OpenAI, Anthropic or Groq, depending on its configuration. This generates general guidance and is not a diagnosis.

There is no automatic removal of identifying information from the text you enter. Do not include names, email addresses, phone numbers or other identifiers. Provider retention and training settings have not been verified for this service; we cannot promise that submitted information is immediately deleted or excluded from model training.

Data Storage and Security

Checker answers are held in application memory in your browser, not saved by the checker to cookies or browser storage. They may remain while you navigate within the site. Restart clears those answers and the displayed result; a full page reload starts a new checker state. Neither action deletes information already sent to our server or an AI provider.

The advice endpoint marks responses private and no-store to prevent caching. This flow does not write answers to an application database. That does not establish what hosting or provider logs retain. The site and provider requests use HTTPS; this is not a guarantee of absolute security or evidence of an independent security audit.

Third-Party Services

We may use third-party services that collect information:

  • AI providers: The configured provider receives the prompt described above to generate guidance.
  • Formspree: When the contact form is configured, your name, email address, subject and message are submitted to its configured endpoint. Avoid sending health details through the contact form.
  • Cloudflare: Hosts the service and processes requests. A separate Cloudflare Web Analytics beacon can be enabled by deployment configuration. Google Analytics is separate from that beacon.
  • Journey by Mediavine: Our advertising partner. It and the ad networks it works with may set cookies or similar identifiers to select and measure the ads you see, and may collect information such as your IP address, device and browser details, and the pages you view on this site. See the Mediavine Privacy Policy. You can manage personalised advertising through YourAdChoices or Your Online Choices, and through your browser's cookie settings.
  • Hosting providers: For service delivery and request processing

We do not pass the symptoms or other details you enter into the symptom checker to our advertising partner. Our advertising partner does receive the address of the pages you visit on this site, and some of those addresses name a symptom or condition.

Your Rights Under Australian Privacy Law

You have the right to:

  • Access: Request access to your personal information
  • Correction: Request correction of inaccurate information
  • Deletion: Request deletion of your information (subject to legal requirements)
  • Opt-out: Opt out of non-essential data collection
  • Complain: Lodge a complaint about our privacy practices

Children Privacy

The checker includes age groups for children. If you enter information about a child, do not include their name, contact details or other identifiers. Their health answers follow the same server and provider processing described above. Contact us with concerns about information already submitted.

Data Retention

Browser answer state lasts until it is reset or the page is fully reloaded. Retention periods for hosting logs, AI-provider requests and contact messages have not been verified for this service. Clearing the checker does not clear those records. Contact us with questions about information you have already submitted.

International Data Transfers

Your information may be stored on servers located outside Australia. Processing locations and contractual safeguards depend on the services and account settings in use; these have not been verified here.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of our service constitutes acceptance of any changes.
