Privacy
No Images Are Stored
The camera is used only for live movement detection in your browser. The app does not save, upload, or store photos, video, camera frames, or body landmark images.
What Is Processed
MediaPipe Pose estimates elbow and wrist positions on your device so the app can count when one wrist is above its elbow and the active side switches. This processing happens live during the run.
What May Be Saved
If you choose to save to the leaderboard, Firebase stores your cleaned username, score, and timestamp. The username is optional; choosing Skip Leaderboard, or saving with a blank username, does not create a leaderboard record.
Third-Party Services
The app loads MediaPipe scripts from jsDelivr and uses Firebase Hosting and Firebase Realtime Database for the site and optional leaderboard. Do not enter personal information as your username.
