At a glance

No uploads

The app has no network permission and does not send data to a remote server.

Stored locally

Test records, person entries, and optional photos are stored on your Android device.

Under your control

You can turn off photo capture and delete local history records and photos in the app.

01

Scope

This Privacy Policy applies to the Alcohol Meter Android application (the “App”). The App connects to compatible breath alcohol testing devices through Bluetooth, displays test results, and lets the user choose whether to keep test records and photos on the device.

The App does not require an account, does not contain advertising, and does not provide cloud synchronization.

02

Data handled by the App

To provide its core functions, the App may handle the following information on your device:

  • Testing-device information: Bluetooth device name, Bluetooth address or MAC address, model, serial number, software version, and device settings.
  • Test records: test time, alcohol measurement, display unit, record sequence number, and record source.
  • Information entered by the user: an optional person name or identifier and vehicle plate number.
  • Optional photos: photos taken during a test when automatic capture is enabled and the image passes the App's local face-completeness check.
  • App settings: language, camera preference, recent connection state, and local device-related settings.

This information comes from you, your Android device, or the connected testing device. The App itself does not declare network permission and therefore does not directly upload this information to a remote server.

03

Device permissions and purposes

Bluetooth Scan & Connect

Used to discover, identify, and connect to compatible testing devices and exchange commands and results between the device and phone.

Location (Android 11 and earlier only)

Older Android versions associate Bluetooth scanning with location permission. The App requests it only to scan for Bluetooth devices and does not read, record, or infer your geographic location.

Camera

Used for camera preview and optional automatic photo capture during a test. Camera capture can be disabled in Settings. A photo is not saved when a complete face is not detected or the image does not meet the save conditions.

Face detection is used only to determine whether a complete face is present before saving a photo. It is not used to identify a person and does not create a face template.

04

Local storage, backup, and deletion

Test records are stored in the App's local database, and photos are stored in the App's internal files directory. When you deliberately export a photo, a copy is placed in the Android system photo library. Information is generally retained until you delete the relevant record in the App, clear the App's data, or uninstall the App.

You can delete records, names, plate numbers, and photos through the history and person-management features. Once deletion is completed, the corresponding local content cannot be recovered through the App.

Depending on your Android settings, Android system backup or device-transfer services may process some App data. Those services are controlled by your device or platform provider and are not remote services operated by the App.

05

Data sharing and third-party services

The App does not sell, rent, or share personal information, test records, or photos with advertisers. The App does not integrate advertising, user analytics, or crash-reporting services.

The App uses Android platform components, AndroidX, Room, CameraX, and the Google ML Kit face-detection library to provide local functionality. The current version has no network permission, and ML Kit face detection is performed on the device. If you deliberately use Android export, sharing, backup, or device-transfer features, data may be handled by the system app or service you select and is then subject to that provider's privacy practices.

06

Security measures and your choices

The App stores internal data within the Android app sandbox and minimizes permissions and network exposure. No form of device storage can be guaranteed to be absolutely secure. Protect your device lock credentials and use care when exporting records that contain a person's name, vehicle plate, or photo.

You may deny camera permission or turn off automatic photo capture; the core Bluetooth testing flow can still be used without taking photos. Denying Bluetooth-related permissions prevents device discovery and connection.

07

Children's privacy

The App is intended for adults and professional users who need to operate compatible breath alcohol testing devices. It is not directed to children. Do not use the App to intentionally collect a child's name, photo, or other personal information.

08

Changes to this policy

This policy may be updated when the App's features, data practices, or applicable requirements change. The revised version will be posted on this page with a new effective date shown at the top.

09

Support channel

If you have questions about this policy or the App's data practices, contact support through the sales, download, or technical-support channel from which you obtained the App. Do not submit test records, photos, or other sensitive information through a public channel.
