DATA COLLECTION

Carrilero does not require user registration or account creation. We track gameplay results using a soft fingerprint generated as a SHA-256 hash of your IP address and browser User-Agent header. This information is stored securely on the server and is used solely for:

  • Preventing multiple daily submissions.
  • Tracking consecutive-day solve streaks.
  • Providing global puzzle solve stats.

COOKIES & AD PARTNERS

We may use advertising services (such as Google AdSense) to display ads. These third-party services use cookies to serve ads based on user visits to our site and other sites on the internet.

You can opt out of personalized advertising by visiting Google's Ads Settings or your browser preferences.

DATA SECURITY

All fingerprints and scores are stored in a secured PostgreSQL database. We do not sell or share any user identification signatures.
