Referee.Observer (“we”, “our”, or “the service”) is a global football referee tracking and analytics platform available at referee.observer. The service is operated by OK Factory.

2. Information we collect

We collect information in the following ways:

  • Account data — when you register or sign in with Google, we store your email address, name, and a Google account identifier.
  • Profile data — optional information you provide in your official profile (city, license details, physical measurements, etc.).
  • Usage data — pages visited, features used, and interaction logs for analytics and performance monitoring (via Vercel Analytics).
  • Fitness data — if you connect a wearable device, we store activity summaries you authorise us to receive.

3. How we use your information

  • To provide and maintain the referee portal and its features.
  • To authenticate you securely when you sign in.
  • To display your appointment history and performance statistics.

We request the minimum required scopes: openid, email, and profile. We do not access any other Google account data.

5. Data storage and security
