This data is stored on our secure servers to track your progress over time.

Camera and Movement Analysis Data

• Camera video feed
• Facial landmark coordinates
• Body pose landmark coordinates

We do NOT store, transmit, or have access to this raw data.

Calculated Metrics (Collected)

Movement measurements derived from on-device analysis (such as angles and ranges) are transmitted to our servers to provide personalized rehabilitation guidance.

Data Sharing

Tusoon does not sell, rent, or share user data with third parties.

Third-Party Services

Tusoon does not use third-party analytics, advertising SDKs, or tracking tools.

Data Retention

• Raw camera and facial landmark data: Never stored; discarded immediately after on-device processing.
• Exercise measurements and progress: Retained until you delete your account.
