Data Ownership & Privacy

HealthyPi Move is designed with a privacy-first philosophy. Your health data belongs to you, and you have complete control over how it's stored, accessed, and shared.

Your Data, Your Control

Core Privacy Principles

  • You own your data - All health metrics collected by HealthyPi Move are your property
  • Local storage first - Data is stored on your device, not on external servers
  • No cloud dependency - Your data never leaves your control without your explicit action
  • No third-party sharing - We do not sell, share, or transmit your health data to any third parties
  • Full export capability - Export your data anytime in open, standard formats

How Your Data is Stored

On-Device Storage

All biometric measurements (ECG, heart rate, SpO₂, temperature, activity, etc.) are stored directly on the HealthyPi Move device in internal flash memory. The device can store:

  • Continuous heart rate, temperature, and activity data
  • 30-second ECG recordings
  • SpO₂ measurements (on-demand)
  • Historical trends and metrics

Mobile App Storage

When you sync your HealthyPi Move with the mobile application, data is transferred directly from the device to your smartphone via Bluetooth Low Energy (BLE). This data is stored:

  • Locally on your phone - in the app's secure storage container
  • Not in the cloud - no automatic upload to external servers
  • Under your control - only accessible through your mobile device

Data Access & Export

You have complete access to retrieve and export your health data at any time.
