What data Flutter BLE collects
Your privacy policy must disclose each of the following data types when you use Flutter BLE.
When does Flutter BLE trigger privacy obligations?
Installation Threshold
Flutter BLE triggers privacy obligations the moment you integrate the library into your app and connect to any Bluetooth Low Energy peripheral. Unlike web-hosted SDKs, Flutter BLE operates at the OS level on Android and iOS, collecting data before any user interaction occurs—during device discovery and GATT characteristic reads.
Specific Data Flows That Activate Obligations
Bluetooth device identifiers (MAC addresses, UUIDs) constitute personal data under GDPR Article 4(1) and CCPA Section 1798.100 because they identify devices that individuals control. This is true even if the BLE device is anonymous to users. The moment your app scans for peripherals or reads GATT characteristics, you are collecting and processing identifiers.
Sensor data (heart rate, location-adjacent readings, motion data) from health/fitness wearables is special-category data under GDPR Article 9 and triggers heightened obligations—particularly if your app targets iOS Health app integration or Android Health Connect.
