4. California Consumer Privacy Act (CCPA) / CPRA Notice

For players residing in California, the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA) provide specific rights regarding personal information. We do not sell your personal information for money. However, the use of third-party advertising cookies may be classified as a "sale" or "sharing" of information under California law.

5. Web Camera & MediaPipe Motion Detection

Our game features real-time webcam motion tracking powered by Google MediaPipe. We care deeply about your privacy:

All camera feed processing for hand landmarks is performed entirely local (on-device) in your web browser.
No video frames, camera feeds, or image data from the tracking session are sent to our servers for hand detection.
Camera permissions are requested solely so local scripts can count game repetitions and render feedback.
You can deny camera access and still play in keyboard mode (keys 6 and 7).

6. Data Collection & Leaderboards

When you play 67 Speed Challenge, we collect and store limited game-related data to manage the high-score leaderboards:

Leaderboard entries: If you achieve a competitive score and choose to submit it, we store the pilot callsign/name you enter, your score, reps count, speed (reps/sec), mode context, date, and a server-generated timestamp.
Storage: These scores are stored on Google Firebase Firestore and displayed publicly to other players.
Local storage: We use your browser's Local Storage to store local high scores and language preference.
Contact form: If you message us via the Contact page, we receive the information you submit so we can respond.

7. Children's Privacy

We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has submitted leaderboard data to our Site, please contact us, and we will promptly remove the entry from our database. Supervising adults should decide whether webcam use is appropriate for their household.

8. International Users

The Site may be accessed from outside your country of residence. By using the Site, you understand that limited data (such as submitted leaderboard entries or contact messages) may be processed using infrastructure providers that operate in other regions, subject to their safeguards.
