To offer heart rate and blood pressure estimation features, our App utilizes Remote Photoplethysmography (rPPG) technology using your device’s front or rear camera.

• Data Collection & Processing: When you initiate a scan, the App uses your camera feed to detect minute ambient light variations reflected from the skin of your face or fingertip.
• Derived Health Metrics: The output generated from an rPPG scan consists solely of numerical health estimates (e.g., heart rate in BPM, estimated blood pressure). These numerical values are stored locally on your device & in your encrypted account cloud storage to allow you to track your health trends over time.
• Use of Data: Your health readings are used strictly to provide in-app wellness tracking and personalized insights. We never sell, rent, or share your biometric, camera, or health data with third-party advertisers, data brokers, or marketing networks.
• On-Device Camera Feed Processing: Camera video feeds are processed in real-time. Raw video and camera image frames are analysed transiently on your device and are immediately discarded. We do not capture, record, store, or transmit your raw face images or raw video data to external servers.
• Data Deletion: You can clear your stored health measurement history at any time through the App settings, or delete your account to permanently remove all associated health logs.
• General Wellness Purpose Only: The heart rate and blood pressure features powered by rPPG technology are intended solely for general fitness, stress tracking, and informational wellness purposes.
