App Privacy Policy — SmartBatchRenamer (改名匠)

Shenzhen Xumiao Technology Co., Ltd. ("we", "us") takes your privacy very seriously. This App Privacy Policy applies to users of 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: The files you select for renaming, including their contents, file names, and directory information, are processed entirely on your local device and are not uploaded to our servers.
    

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. Limited Service Information

To provide software licensing, purchases, technical support, error diagnosis, and related services, we may process limited account, device, transaction, or technical information. We process this information only as necessary to provide, maintain, and improve the relevant services.

This service information does not include the files you select for renaming, their contents, file names, or directory information. Interface settings and rule templates saved locally are not uploaded either.

3. Third-Party Services

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

We may use third-party service providers for sign-in, license verification, payments, updates, technical support, or infrastructure. These providers process the limited information described above only as necessary to provide the relevant service. Update checks do not upload your file data.

Please note: this Policy covers only the desktop app itself. When you visit our official website, www.xumiao.tech, the website may use cookies and third-party website analytics tools; for details, please refer to the Website Privacy Policy.

4. Data Storage and Processing Across Regions

To provide the services described above, limited account, device, transaction, or technical information may be processed by us or third-party service providers in different countries or regions. We use reasonable contractual, organizational, and technical measures to protect this information in accordance with applicable law.

The Software does not automatically attach your file contents, file names, or directory information to a Feedback message. Do not voluntarily include personal information or file information that is not needed to resolve your issue.

We retain information only as long as necessary to provide the relevant service, maintain required records, resolve disputes, or meet legal obligations. You may contact us through the in-app Feedback feature or the email address below to withdraw consent where applicable or request that we handle relevant information.

5. Your Rights

Under applicable law, you may have rights to access, copy, correct, supplement, and delete your personal information, as well as the right to deactivate your account or withdraw consent where applicable. The backend information we process is limited to business information needed to provide the relevant services; your file data always remains on your local device. To exercise these rights, contact us using the details below, and we will respond within the time limits prescribed by law.

6. 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.

7. 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 children under the age of fourteen. 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.

8. 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.
