3. How Key Defender Collects and Uses Your Information (Including Personal Information)

Personal information refers to various information recorded electronically or by other means that can identify a specific natural person's identity alone or in combination with other information, or reflect the activities of a specific natural person. Personal sensitive information includes personal biometric information (e.g., fingerprint, facial features, voiceprint), identity document numbers, bank account numbers, property information, transaction information, whereabouts trajectory (e.g., home and office addresses).

We will only collect and use your information for the purposes listed in this statement:

a) Request phone permission, including access to phone identifier permission

Our product integrates Umeng+ SDK to provide statistical analysis services. Umeng+ SDK needs to collect your device MAC address, unique device identifier (IMEI/android ID/IDFA/OPENUDID/GUID/SIM card) and calibrate report data accuracy through geographic location to provide basic anti-cheating capabilities. The privacy policy for this product can be found at: https://www.umeng.com/page/policy

If you do not wish to provide the above information, you can enter "Settings" - More settings - "App Management" - "Key Defender" - "Permissions" - "Phone" to disable this permission;

Explanation regarding the Umeng+ Statistical Analysis SDK collecting "Android ID" in the background under certain scenarios:

During first use, after the user agrees to the relevant terms, Key Defender will initialize related components and cooperate with the Umeng+ Analytics SDK for smart hardware usage scenarios. Under the smart hardware background detection connection keep-alive strategy, the collection state is maintained. This process is generally completed within 2-3 seconds to ensure the continuity of statistical analysis. After successful collection, the program securely caches the data and will not obtain it frequently.

b) External Storage Permission

Key Defender supports selecting pictures from the album as user avatars. This feature requires access to the phone's storage permission. If you do not need this feature, you can disable this permission at any time in "Settings" - "More settings" - "Key Defender" - "Permissions" - "Storage";

c) Location Information: Location Permission

Reason for our use of location permission:

We provide Bluetooth Low Energy (BLE) device connection functionality. This function requires the use of the phone's location permission on systems above Android 6.0;

SDK Name Used: AMap Open Platform Location SDK

Third-Party Name: AutoNavi Software Co., Ltd.

Purpose of Use: To achieve positioning/display maps (obtain the user's current location through positioning and automatically display the distribution of nearby locksmith shops)

Personal Information Collected: Location information, device information (including IMEI, IDFA, Android ID, MEID, device MAC address, OAID, IMSI, SUPI, SUCI, hardware serial number, software installation list, location, contacts, call logs, calendar, SMS, local phone number, pictures, audio/video), network status and WiFi information (WiFi status, IP address, SSID, BSSID, etc.)

For details on the personal information collected and used by the SDK, see: https://lbs.amap.com/agreement/sample

When using features involving third parties, you may be redirected to a third-party application or website. We strongly recommend that you carefully read the service terms and privacy policy of that third party, as we have no control over third-party applications or websites and bear no responsibility for any damage caused by third parties to your rights;

f) Using Clipboard Services

We will call the system clipboard service to copy answers to questions searched by users in the help center to the clipboard. We will not use the clipboard service without any action from you.

g) BSSID

Purpose: To provide users with location services and improve the positioning success rate of the application, we will collect the BSSID of the WIFI your device is connected to. It is used by the server for network WiFi positioning, optimizing positioning strategies, and displaying the distribution of nearby service outlets based on location information.

Method: When the application starts and when the network status changes, collect the BSSID of the currently connected WIFI through the system's standard WIFI information acquisition interface.

Scope: Collect the BSSID, SSID and other related information of the WIFI your device is currently connected to.
