App Privacy Policy (Global) — SmartBatchRenamer

Shenzhen Xumiao Technology Co., Ltd. ("we", "us") takes your privacy very seriously. This App Privacy Policy applies to users outside mainland China and covers only 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.

      Core commitment: SmartBatchRenamer is local-first. The files you add and every rename operation on them are processed 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 core functionality of the Software — including reading file lists, previewing rename results, executing renames, and undoing operations — runs locally on your device. This means:

The contents, names, and paths of files you drag in or select always stay 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 directories.
The full functionality of the Software requires activating a VIP membership, and activation and membership verification require an internet connection. This process only verifies your account and membership entitlements and never uploads any of your file contents; after activation, rename operations still act directly on your local file system.

2. Information We Collect

During normal use, the Software involves the following information:

Account information: Using the Software requires signing in. We use your sign-in information only to distinguish between users; we do not use it for any other purpose, including user profiling, marketing, or sharing with third parties.
File information: As described above, file contents and names are processed locally only and are never accessible to us.
Local settings: Your preferences (such as UI theme and frequently used rule templates) are stored only in your device's local storage and are never uploaded.

3. Third-Party Services

The Software does not integrate any third-party advertising, 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 and never sends any of your file data or personal information 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 Google Analytics and Google Tag Manager — see the Website Privacy Policy for details.

4. Your Privacy Rights

Depending on where you live, U.S. state privacy laws — such as the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA) — may give you rights to know what personal information we hold about you, to request access to or deletion or correction of that information, and to opt out of the "sale" or "sharing" of personal information.

We do not sell or share your personal information, and we do not use it for cross-context behavioral advertising. Because the Software is local-first, the only personal information we retain on our servers is the account identifier used to distinguish users; nearly all of your data stays on your 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.

5. Data Security

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.

6. Children's Privacy

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 (or any user). If you believe a child has provided us with personal information, please contact us and we will delete it.

7. Changes to This Policy

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.
