Yes. For the emergency alerts to be sent, your Plegium device must maintain a Bluetooth connection to your phone (which requires it to be within about 2–3 meters), and the Plegium app must be open. If you fully close the app, the device will disconnect and the app won’t detect when you activate the device—meaning no emergency alerts will be sent. The device reconnects automatically when you open the app again or move it back within Bluetooth range. You can always check the connection status in the Plegium app.
Note that the app only controls the emergency alert features. If your spray is not connected to your phone and therefore cannot send emergency alerts, the spray’s other functions—such as the menthol spray, LED light, and siren—are not affected and will still work as normal.
