Privacy Policy

What we collect, how we use it, and the choices you have.

Last updated: August 29, 2026

1. Information we collect

Account data: the email address you register with.

Health screening data: your VCS test results, any symptom-quiz answers, and the reports generated from them.

Technical data: browser type, screen size, and the calibration value you set (pixels-per-millimeter), which we store locally on your device and in a cookie.

Usage data: aggregate, anonymized analytics about how the Service is used.

2. How we use your information

  • To run the screening, save your results to your account, and generate your reports
  • To provide the advanced reports you purchase
  • To improve calibration, scoring, and the overall experience
  • To send essential account and service-related messages

3. Local storage and cookies

We store your screen-calibration setting in your browser's localStorage and in a cookie so the setting persists across sessions and devices. No third-party advertising cookies are set by us.

4. Data sharing

We do not sell your information. We share data only with service providers that help operate the Service (such as hosting, email delivery, and payment processing), under agreements that limit their use of your data, and where required by law.

5. Data retention

We keep your screening results and reports for as long as your account is active. You may request deletion of your data at any time through the Contact page.

6. Security

We use reasonable technical and organizational measures to protect your data. No method of transmission or storage is perfectly secure, so we cannot guarantee absolute security.

7. Your rights

Depending on your jurisdiction, you may have the right to access, correct, export, or delete your personal data, and to object to certain processing. Exercise these rights through the Contact page.

8. Children's privacy

The Service is not directed to children under 18 without a parent or guardian's involvement. We do not knowingly collect data from minors outside that context.

9. Changes to this policy

We may update this Privacy Policy. Material changes will be posted with a new "Last updated" date.
