1. Overview
ATMO Pulse ("the Application") is committed to protecting your privacy. This Privacy Policy explains how we handle your data when you use our heart monitoring application. The Application is intended for wellness and informational purposes only.
Key Principle: All data is processed and stored locally on your device. We do not transmit, collect, or store any of your health data on remote servers.
2. Data Collection and Processing
2.1 Camera Access
Purpose: The Application accesses your device's camera to capture video frames for photoplethysmography (PPG) heart rate detection.
What We Collect:
- Real-time video frames from the rear camera
- Brightness values extracted from video frames
- Timestamps of measurements
What We Do NOT Do:
- We do NOT record or store video files
- We do NOT transmit video data to any server
- We do NOT use facial recognition or biometric identification
- The Application does not identify individuals or perform biometric identification of any kind
- We do NOT access the front-facing camera
Video frames are processed in real-time on your device. Only brightness values are extracted and analyzed. Raw video data is discarded after processing. Camera access is used only during active measurement initiated by the user.
2.2 Health Data
What We Collect:
- Heart rate measurements (BPM)
- Heart rate variability (HRV) metrics derived from signal analysis
- Derived physiological metrics (e.g. RMSSD)
- Measurement timestamps
- Signal confidence scores
Storage: All health data is stored exclusively on your device in local application storage. No cloud synchronization. No automatic backup to cloud services. No transmission to third parties.
2.3 User Settings
The Application stores your preferences (alert sounds, measurement units, medical disclaimer acknowledgment) locally using device secure storage. This data is never transmitted to any server.
3. Third-Party Services
The Application does not:
- Share data with third-party analytics services
- Integrate with cloud storage services

- Transmit data to any external service
Platform Permissions Requested

4. Data Security
All signal processing occurs on your device using a C++ core engine. The Application does not send any data over the internet. No data transmission during processing. No network connectivity required. Processing is deterministic and reproducible.
Your data security depends on your device's operating system security, lock screen protection, and application sandbox isolation.
