PurrBPM may store the following data locally on your Mac:

• Live heart-rate readings and saved recordings
• Device names shown by nearby Bluetooth heart-rate devices
• Bluetooth diagnostic logs shown inside the app
• App settings, including zones, alerts, and recording preferences
• Optional activity samples if Activity Tracking is enabled
• Optional browser domains if Browser Domain Tracking is enabled
• CSV files only when you choose to export them

Activity Tracking is off by default. If enabled, PurrBPM can store active app names with heart-rate samples while your Mac is in use. Activity sampling pauses after keyboard and mouse inactivity.

Browser Domain Tracking is separate and off by default. If enabled, macOS may ask for automation permission so PurrBPM can read the active browser domain from Safari, Chrome, Brave, Edge, or Chromium. If permission is denied, the rest of the app continues to work.

PurrBPM does not collect data from you. It has:

• No account system
• No analytics
• No ads
• No telemetry
• No third-party tracking SDKs
• No cloud upload

Your heart-rate readings and recordings stay on your Mac unless you choose to export a CSV file.

You can delete saved recordings in the Recordings screen. You can clear Activity Tracking history in Settings.

PurrBPM is not a medical device and does not diagnose, treat, or prevent any condition. It is intended only to display heart-rate data from compatible Bluetooth Heart Rate Profile devices.
