Visitor Map

Every visit to the Clube is recorded anonymously — only country and approximate city (via IP). No IP stored, no tracking cookie, no data sales.

Pure curiosity: we want to know who's studying.

How it works

  1. When you open the site, we make a request to ipapi.co (free service) which returns your approximate country by IP.
  2. We increment an anonymous counter at CounterAPI.dev like clube-pais-br, clube-pais-de, etc.
  3. This page reads those counters and shows the aggregate. No personal data is stored at any time.
  4. Each browser session counts once (controlled by sessionStorage).
