+
+**LocationSync for Sony** ("the app") is provided as a free app. This page informs you about the data collected when you use the app.
+
+## Data Collected by the App
+
+### Location Data
+
+The app accesses the device's GPS location exclusively to transmit it to your connected Sony camera via Bluetooth Low Energy (BLE). Location data is processed entirely on-device and is never transmitted to any server or third party.
+
+### Bluetooth Data
+
+The app scans for and connects to nearby Bluetooth devices to identify and communicate with a paired Sony camera. Bluetooth device names and addresses are stored locally on the device (in app preferences) only to remember your selected camera between sessions. This data is never transmitted to any server or third party.
+
+## Third-Party Services
+
+The following third-party services are active in release builds of the app. They are not active in debug builds.
