Only your progress is stored. Your camera is never involved: video is processed on your device and never uploaded, signed in or not.

where your data lives

Progress lives in this browser by default. Hand tracking runs via WebAssembly, video frames are never uploaded, and nothing from the camera is stored. Sign in to sync XP, streaks, and gems across devices — still no camera uploads. Opt-in landmark sharing stores joint positions only — see Landmark contribution below.
