Privacy Policy - IW Radar

Last Updated: 2026-10-10

Effective Date: 2026-10-10

IW Radar (the “App”, “we”, “us”, or “our”) is a utility application for connecting to radar devices and performing debugging/configuration operations. We take your privacy seriously and process personal information in accordance with applicable laws and the AppGallery review guidance.

Please read this Privacy Policy carefully before using the App. If you do not agree with any part of this Policy, please stop using the App. By continuing to use the App, you acknowledge that you have read, understood, and agreed to this Policy.

1. How We Collect and Use Personal Information

We follow the principles of legality, legitimacy, necessity, good faith, and data minimization. We may collect and use information in the following scenarios:

(1) Account Login and Authentication

When you sign in, you provide account credentials (username and password).
We use your credentials to authenticate with our backend services and store an authentication token locally to maintain your login session.
If you enable “Remember me”, the App may store your username and password locally on your device for convenience. You can disable this option and clear local storage at any time.

(2) Bluetooth Device Discovery, Connection, and Communication (Core Function)

To discover and connect nearby radar devices, the App uses Bluetooth capabilities.
During scanning/connection, the App may process device-related data such as: Bluetooth device name, device identifiers (e.g., MAC/DeviceId), RSSI (signal strength), and connection status.
This information is used to support device discovery, pairing/connection, command delivery, data receiving, and debugging records.

(3) Location Permission (Required by System for Bluetooth Scanning)

On some platforms (e.g., Android, HarmonyOS, WeChat Mini Program), the operating system may require location services to be enabled or location permission to be granted in order to scan Bluetooth devices.
In this scenario, the App may request location permission, but the App does not actively collect or upload your precise GPS coordinates for business purposes (unless future versions introduce location-based features with separate notice and consent).
If you deny location permission, Bluetooth scanning/discovery may not work properly.

(4) File Selection, Reading, Saving, and Sharing (e.g., Firmware Upgrade, Log Export)

When you select firmware files (e.g., .bin/.zip) for upgrade, or import/export debugging files, the App needs access to the files you choose.
When you export logs/reports and share them, the App may save files to the App’s private storage or a location you authorize, and invoke system sharing features.
The App does not read other files on your device without your explicit action.

(5) Operation Logs and Troubleshooting Data

To improve stability and diagnose issues, we may record and upload debugging-related operation logs (e.g., command name/value, timestamps, device identifiers, Bluetooth name, and the logged-in username).
We do not use sensitive personal information such as call logs, SMS, biometrics, health data, or movement trajectories for non-core purposes such as advertising or marketing.

2. How We Share, Transfer, or Publicly Disclose Personal Information

(1) Sharing

We do not share your personal information with third parties unless described in this Policy or with your separate consent. We may share necessary information in the following circumstances:

To provide core capabilities via system/platform services (Bluetooth, location permission status, file picker, networking APIs, etc.).
To comply with legal obligations and requests from competent authorities.
To protect security and prevent fraud, abuse, or illegal activities.

(2) Transfer and Public Disclosure

We do not transfer or publicly disclose your personal information. If it becomes necessary, we will comply with legal requirements and obtain your separate consent (unless otherwise required by law).

3. Third‑Party SDKs/Components

This application is developed based on DCloud uni‑app (5+ App/Wap2App). During app runtime, it may collect your device unique identifiers (IMEI / Android ID / DEVICE_ID / IDFA, SIM‑card IMSI, OAID) to provide statistical analysis services. App launch statistics and crash logs are collected to improve application performance and user experience. Please refer to the DCloud App Engine Privacy Policy for further details.

This App also uses certain open‑source third‑party components for UI rendering and fundamental capabilities. We evaluate compliance risks and oblige those components to fulfill relevant data‑protection responsibilities.

4. Permissions

We request permissions only when needed for specific features and aim not to impact the App’s basic functions if you deny non-essential permissions (but certain features may be unavailable).

Permission/Capability	Purpose	Impact if Denied
Bluetooth	Discover and connect radar devices; debugging communication	Bluetooth scanning/connection/debugging will not work
Location (service/permission)	Required by some platforms for Bluetooth scanning	Device discovery may fail on certain platforms
Storage/File access	Select firmware files; import/export debugging files; save/share logs	File selection/export/sharing may be unavailable
Network	Login, version checks, fetch upgrade files, upload operation logs	Online features will be unavailable without network
Camera/Microphone (if applicable)	Potential use for capturing on-site records (if the current version provides such features)	Related capture/recording features (if any) will not work

5. “Double Lists” for Personal Information Protection

(1) List of Collected Personal Information

Data Type	Purpose	Scenario
Account info (username, password)	Authentication and account management	When you sign in
Session state (token)	Maintain login session; API authorization	When using login-required features
Device info (e.g., OS/app version, network status)	Stability, compatibility, troubleshooting	App runtime and issue diagnosis
Bluetooth device info (name, identifiers, RSSI, status)	Discovery, connection, and debugging communication	When scanning/connecting/debugging devices
Operation logs (command data, timestamps, device info, username)	Audit/traceability, troubleshooting, service improvement	When you operate debugging features and upload logs
Files you choose (name, size, content)	Firmware upgrade; import/export of debugging files	When you explicitly select files

(2) List of Shared Personal Information with Third Parties

Recipient	Shared Data	Purpose	Method
System/Platform services (Android/iOS/HarmonyOS/WeChat, etc.)	Permission status and Bluetooth-related data returned by OS APIs	Enable Bluetooth scanning/connection, file picker, networking	Via system APIs

6. Storage and Security

(1) Retention

We retain personal information only for the minimum period necessary to achieve the purposes described in this Policy, unless otherwise required by law.
Some information is stored locally on your device (e.g., token, “remember me” data, device debugging parameters) to improve user experience.

(2) Security Measures

We use encrypted channels such as HTTPS for network transmission.
We implement reasonable safeguards to protect data against unauthorized access, disclosure, alteration, damage, or loss.

7. Your Rights

You have rights under applicable laws, including access, copy, correction, deletion, and withdrawal of consent. You can exercise these rights by:

Withdrawing permissions: disable Bluetooth/location/storage permissions in system settings (or the WeChat Mini Program settings).
Clearing local data: log out in the App and clear app data or uninstall the App.

We will respond within a reasonable time as required by law (generally within 15 business days).

8. Children’s Privacy

The App is primarily intended for professional/enterprise users for device debugging. If you are a minor, please use the App with your guardian’s consent and guidance.

9. Updates to This Policy

We may update this Policy from time to time. If the changes materially affect your rights, we will provide more prominent notice and obtain your consent when required.
