What the app does
Bluetooth pairing
Connect directly to a compatible LU&BA device from your phone. No hub, no shared account.
Intensity level
Set the output level within the range your device model supports, and change it at any time.
Operating modes
Choose the mode that your device model offers, and switch modes between sessions.
Session duration
Set how long a session should run, watch the remaining time, and let the app stop the device at the end.
Consumable check
Scan the QR code on a consumable with the camera, or pick a single picture from your gallery, to verify that it is genuine and check how much of it remains.
Usage records
Review past sessions and keep the records you choose to save to your account.
Offline operation
Operate the device over Bluetooth without a network connection, then synchronise your records later.
The app displays operating parameters of the paired device — level, mode, remaining time, consumable status and firmware version. These are device readings, not health measurements.

Your data
To run your account and operate the device, the app processes your email address, the Bluetooth hardware address of the device you bind, the device name, model and firmware version, the latitude and longitude read once at binding, the operating records of your sessions, and basic technical details such as the app version and the Android version of your phone. When you run a consumable check it also processes the code decoded from the QR label; the image itself is decoded on your phone and is never uploaded.
It does not read your contacts, messages or call log, it does not use the microphone, and it does not browse your photo library — the only image it ever receives is the single picture you pick yourself for a consumable check. It contains no advertising or analytics software. Our application servers are located in mainland China, so your data may be transferred outside the country you live in. Read the Privacy Policy for the full description, including how to request deletion of your account and data.
Important notice
Stop using the device and seek professional advice if you experience pain, unusual redness, swelling or any adverse reaction. If you have a skin condition, are pregnant, or use an implanted electronic device, consult a qualified healthcare professional before use.
