Applies to the SmartBatchRenamer desktop app · Last updated: September 5, 2026
Shenzhen Xumiao Technology Co., Ltd. ("we", "us") takes your privacy very seriously. This App Privacy Policy applies to users of the SmartBatchRenamer desktop app ("the Software"). It explains how the Software handles information related to you. For how our official website (www.xumiao.tech) handles visit data, please see the Website Privacy Policy. Please read and understand this policy carefully before using the Software.
All core functionality of the Software — including reading file lists, previewing rename results, executing renames, and undoing operations — runs locally on your device. This means:
To provide software licensing, purchases, free-allowance metering and abuse prevention, technical support, error diagnosis, and related services, we may process limited account, device, transaction, or technical information, including a device identifier used to recognise the installation (an app-specific hash derived from your operating system's machine identity) and free-allowance usage recorded per account and per device. 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.
The Software does not integrate any third-party advertising, 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 — see the Website Privacy Policy for details.
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 request access, correction, or deletion of relevant information.
Depending on where you live, you may have rights to access, correct, delete, restrict or object to processing, receive a portable copy of your data, and opt out of the "sale" or "sharing" of personal information. The specific rights available to you depend on applicable law.
We do not sell your personal information or use it for cross-context behavioral advertising. 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 any of these rights, contact us using the details below, and we will respond as required by applicable law. We will not discriminate against you for exercising your privacy rights.
Because your files and settings are stored on your local device, their security is primarily protected by your device and operating system. We recommend keeping your device secure and backing up important files regularly to prevent data loss from accidental operations or device failure.
The Software is a general-purpose file management tool. It is not directed to children, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.
We may update this Privacy Policy from time to time. When material changes occur, we will update the "Last updated" date on this page or notify you within the Software. We encourage you to review this page periodically for the latest information.
If you have any questions, comments, or suggestions about this Privacy Policy, please contact us:
