App Privacy Policy (China) — SmartBatchRenamer (改名匠)

Shenzhen Xumiao Technology Co., Ltd. ("we", "us") takes your privacy very seriously. This App Privacy Policy applies to users in the Chinese mainland who use the SmartBatchRenamer (改名匠) desktop app (the "Software"), and explains how the Software handles personal information relating to you. For how our official website (www.xumiao.tech) handles visitor data, please refer to the Website Privacy Policy. Please read and understand this Policy carefully before using the Software.

      Core commitment: SmartBatchRenamer is built around local processing. The files you add and every renaming operation performed on them are completed entirely on your local device. We do not upload, collect, store, or share with any third party your file contents, file names, or directory information.
    

1. How We Handle Your Files

All of the Software's core functions — including reading file lists, previewing rename results, performing renames, and undoing operations — are completed locally on your device. This means:

The contents, file names, and paths of the files you drag in or select always remain on your device and are never transmitted to our servers or any external network.
The Software does not scan, upload, or back up other unrelated files in your file directories.
The Software's full functionality requires activating a VIP membership; activation and membership status verification require an internet connection. This process only verifies your account and membership entitlements and does not upload any of your file contents; after membership activation, renaming operations still act directly on your local file system.

2. Information We Collect

During normal use, the information involved in the Software is as follows:

Account information: Using the Software requires signing in. We use your sign-in information solely to distinguish between different users; beyond that, we do not use it for any other purpose, nor for user profiling, marketing, or sharing with third parties.
File information: As described above, file contents and names are processed locally only and are never obtained by us.
Local settings: Your preferences (such as interface theme and frequently used rule templates) are saved only in your device's local storage and are not uploaded.

3. Third-Party Services

The Software does not integrate any third-party advertising, data analytics, or user behavior tracking SDKs.

The Software's update feature is implemented by us and does not rely on any third-party update service. When checking for updates, the Software only requests version information from our release server; no file data or personal information of yours is sent with the request.

Please note: this Policy covers only the desktop app itself. When you visit our official website, www.xumiao.tech, the website uses cookies and analytics tools such as Baidu Tongji (百度统计); for details, please refer to the Website Privacy Policy.

4. Your Rights

Under the Personal Information Protection Law of the People's Republic of China and other applicable laws, you have the right to access, copy, correct, supplement, and delete your personal information, as well as the right to deactivate your account or withdraw your consent. Because the Software uses local processing, we retain on the server side only the account identifier used to distinguish users, and the vast majority of data resides on your local device to begin with. To exercise the rights above, you may contact us through the contact details below, and we will respond within the time limits prescribed by law.

5. Data Security

Because your files and settings are stored on your local device, their security is primarily protected by the security mechanisms of your device and operating system. We recommend that you safeguard your device and regularly back up important files to prevent data loss caused by accidental operations or device failure.

6. Children's Privacy

The Software is a general-purpose file management tool that is not designed for children, and we do not knowingly collect personal information from any user, including children. If you are the guardian of a minor under the age of fourteen and have any questions about the minor's use of the Software, please contact us.

7. Changes to This Policy

We may update this Privacy Policy from time to time. When material changes occur, we will notify you by updating the "Last updated" date on this page or through a notice within the Software. We recommend that you review this page periodically to stay informed of the latest version.
