BlockRush is operated by Rainier Studio LLC (“XRainier”, “we”).

What we collect

• Player name you choose and a random player id stored on your device.
• Game runs you finish: score, lines, the moves you made (so we can verify the score) and the time.
• Country derived from your IP address by our hosting provider, shown as a flag on leaderboards. We do not store your IP address.

What we do not collect

No email, no password, no advertising identifiers, no third-party trackers or cookies. Game progress and settings are kept in your browser’s local storage.

Hosting

BlockRush runs on Cloudflare. Requests pass through Cloudflare’s network, which may process technical data (such as IP address) to deliver and protect the service.

Retention and deletion

Leaderboard entries are kept while the game is live; duel records older than 120 days are deleted. To remove your player and runs, email support@xrainier.com with your player name.

Children

BlockRush is suitable for all ages and collects no personal contact information.
