Privacy Policy

Effective Date: June 1, 2025 · Last Updated: June 1, 2025

🛡️ Summary: Marble Run stores only your local high score. We collect no personal data, no accounts, and no tracking of any kind.

Glass Marbles, Glass-Clear Privacy

Marble Run is a game of precision and clarity. We apply the same standard to our privacy practices: everything is transparent, nothing is hidden behind layers. The Game creates exactly one piece of persistent data: your high score, stored in localStorage under the key marb_best. This value exists solely on your device. Our servers have no access to it. You may inspect it in your browser's developer tools and delete it by clearing site data for this page.

Server Logs and External Requests

When you load Marble Run, your browser sends an HTTP GET request to our server. The server logs your IP address, browser user-agent, timestamp, and the requested path. These logs support server health monitoring and security. Retention is 30 days. They are not processed by advertising or analytics systems. Marble Run uses the Comfortaa typeface via Google Fonts — one CDN request at page load. If you block this using a browser extension, the Game renders in a system rounded font. No other external requests are made during gameplay.

Children, Rights, and Policy Updates

Marbles belong to everyone. Marble Run is appropriate for all ages. No personal data is collected from any player, young or old. Parents need take no action. Future changes to our data practices will be described in this policy, with a revised effective date, before any change takes effect.

Your Data Rights

Players in jurisdictions with formal privacy rights — including GDPR, CCPA, LGPD, and similar legislation — may request information about data we hold. Because we retain only brief, anonymised server-access logs, such requests will ordinarily confirm that we hold no personal data linked to any individual. We respond within legally required timeframes. To submit a request, use the official Marble Run website or repository contact channel.

No Sale, No Sharing

We do not sell, rent, trade, or share any data with third parties for commercial purposes. If we were ever legally compelled to disclose server-log data — for example, by a valid court order — we would comply with applicable law. We would not do so voluntarily for commercial reasons, because we have no commercial relationship with any data buyer or broker.
