Privacy Policy

Updated: October 2, 2026

The Battery Analysis Tool (hereinafter referred to as "this App") is used to view battery health, device configuration, system operation status and check device function. This Policy explains what information is processed by the App, why it is processed, how it is retained, and how you can manage it.

1. the information we process

• Files of your choice:When you select a file from the system file selector or send a file to the App through system sharing, the App will read the contents related to battery and device configuration in the iPhone Analytics file or sysdiagnose compression package. Files that are not actively selected by you will not be read by this App.
• Analysis results and history:Including battery capacity, health, cycle times, temperature, voltage, power consumption scenario, endurance estimation, device configuration, mask display of hardware identification and related historical records. This content is used to display analysis results and trend changes within this app.
• System operation data:When you use system monitoring, charging rate or related pages, the App will read the current operating data such as battery status, temperature, CPU, frame rate, network, memory, storage space, etc., for display, calculation or estimation in the page.
• Equipment inspection data:Automatic detection will read the device model, system version, processor, operating memory, storage space, screen parameters, maximum refresh rate, battery status and sensor available status; manual detection will record your "normal", "abnormal" or "skip" confirmation of screen, touch control, camera, speaker, keys and other items. Test results and reports are saved on this device.
• Application settings and purchase status:This app may save the completion status of the setup guide, display settings, and the Pro activation status. Purchases are processed by Apple's App Store/StoreKit. This App only receives transaction results and does not read Apple accounts, payment card numbers or payment vouchers.
• Application recommendation status:This App will record whether a recommended application has popped up and whether the recommended banner has been closed during this startup period, which is used to control the number of displays according to settings. These states are not used for user portraits.

Purpose of 2. Permissions

The following permissions will only be requested when you actively start the corresponding machine test project. You can deny permissions; the project may not be completed after denial, but does not affect the functionality that does not require the permission.

• Camera:Used to display the real-time preview of the front, rear, ultra-wide angle or telephoto camera, and confirm whether the flash can be turned on normally. This app will not take pictures, save or upload pictures through the machine checking function.
• Microphone:Used to record about 3 seconds of voice and playback in the machine, so that you can judge whether the microphone is clear. The recording is only stored in a temporary directory, deleted after leaving the test, and will not be uploaded.
• Location when using the app:Used to read positioning accuracy and compass heading to confirm whether GPS and compass can return data normally. The position is only read during the test and is not saved in the test report or uploaded.
• Exercise and Fitness:Used to read pedometer changes, device motion, gyroscope, acceleration and air pressure data to confirm whether the relevant sensors are responding properly. The data is only used for the current detection and will not be saved or uploaded.
• Bluetooth:Used to confirm whether the Bluetooth function is available and the current switch status. The app does not scan, connect, or log nearby Bluetooth devices.
• Face ID：Used to initiate a system verification managed by iOS to confirm that the biometric is responding properly. This App only receives the result of verification and does not read or save face data.

How 3. information is used

This App only uses the above information to parse the files you select, display battery and device data, generate historical analysis and endurance estimates, provide system monitoring, complete device inspection, generate local reports, save usage settings, and confirm Pro rights. Import files, analysis results, machine data, sensor data, and device configurations are not used for cross-app tracking, user profiling, or personalized advertising.

4. storage, retention, export, and deletion

Import files are only used during parsing and validation; after processing, the app cleans up their temporary copies, and you still manage your original files in the Files app or other sources. The analysis results, configuration summary, machine inspection report, application settings, and recommended display status are saved on the device. This App does not create user accounts, nor does it save import files, analysis results or machine inspection reports on its own business server.

You can view and delete single Analytics or sysdiagnose import records in "Settings → Data Management", or clean them all at once. Machine inspection reports can be deleted by sliding in the report list or in the report details. Deleting this app will remove the app data stored on your device.

When you choose to export or share the device verification report, the report is generated locally and handed over to the iOS system’s sharing panel for processing. The report will only be sent to the designated app or service once you have selected and confirmed the recipient; how the recipient handles the report is governed by its own privacy policy.

5. networking capabilities and external services

This App does not use advertising SDK, third-party statistical analysis SDK, does not conduct cross-App tracking, and does not sell personal information. The following features access the network:

• Application Recommended Configuration:This App will read public configurations such as whether to display recommendations, display delay, title and subtitle from Tengxun cloud object storage. The request does not carry import files, analysis results, inspection reports, locations, recordings, camera images, or sensor data. The network service may process necessary connection information such as IP address and request time for providing content and ensuring security.
• App Store Information and Jump:This App will obtain the name and icon of the recommended application through the interface provided by Apple, and open the App Store after you click. Purchase Pro, resume purchase and transaction verification are also handled by Apple's App Store/StoreKit. Data processing is subject to Apple's Privacy Policy and Terms of Service.

App recommendations are not personalized based on your import files, device detection results, or usage behavior. The app does not send import files, analysis results, device configurations, or verification reports to these services.

6. children's privacy

This app does not target children. Minors should obtain the consent and guidance of the guardian before using this App or purchasing Pro.

7. Safety and Accuracy Instructions

We reduce unnecessary data exposure through native processing, temporary file cleanup, least privilege requests, and hardware identification default masks. The analysis and inspection results depend on the file content, equipment model, system version, permission status and your manual confirmation. There may be missing, estimation error or unrecognized items. The results are for reference only and do not represent the official inspection of Apple or maintenance organization.

8. policy changes and contact us

We may update this policy due to functional, legal or App Store requirements. The updated version will be displayed in the App and marked with the update date. For questions about privacy or data handling, send an email kaifaddllreply@163.com。
