Live BMS is designed so that your data stays with you.
Nothing. Live BMS has no user accounts, no analytics, no advertising, and no servers. We receive no data from your use of the app.
Battery readings. The app connects directly to your battery management systems over Bluetooth and reads values such as state of charge, voltage, current, and temperature. These readings and their history are stored only on your device.
Bluetooth is used solely to communicate with your batteries — never to track your location or identify you.
Camera is used only if you choose to scan a battery's MAC/QR label. Images are processed on-device and are not saved or transmitted.
We do not sell, share, or transmit your data, because the app does not collect or transmit any data in the first place.
All history is stored locally. Delete a battery in the app, or delete the app, to remove its stored data.
The app does not collect personal information from anyone, including children.
