Privacy Policy

1. Overview

67Quick (“we”, “us”, “our”) is committed to protecting your privacy. This policy explains what data we collect, why, and how we use it.

2. Webcam Data

The 67Quick game requires access to your device's camera to track hand and arm movements in real time. This tracking is performed entirely within your browser using on-device machine learning (MediaPipe). Your webcam video never leaves your device.

• No video is recorded or uploaded to our servers
• No images are stored from your camera feed
• Motion data (hand positions) is processed locally and discarded immediately after scoring
• You can revoke camera permission at any time through your browser settings
