Privacy Policy

1. Core Commitments

TRANSHI provides local network file transfer and clipboard synchronization. File and clipboard content is transferred between user devices only when initiated by the user. Our company servers do not act as a file relay, and we do not read, analyze or retain users’ transferred files or clipboard content on a long-term basis.

Our own business database only retains login information and purchase/subscription information on a long-term basis, and such information is stored within mainland China.

TRANSHI focuses on local network transfer functions. Local network discovery, connection and transfer performance may be affected by network conditions, device permissions and operating system limitations.

2. Information We Collect and Use

1. Login information: when you register or sign in with an account provided by the Software, or use third-party sign-in channels such as Apple, Google, WeChat and others, we may collect account identifiers, email address, phone number, nickname, avatar and necessary sign-in credentials returned by the relevant platform, depending on your authorization.

2. Purchase information: when you purchase membership, subscription or paid features, we retain necessary information such as order ID, purchase channel, product name, subscription status, validity period, refund or cancellation status. Payments are generally processed by platforms or channels such as the Apple App Store, Google Play, WeChat Pay and others. We do not collect full payment account details such as full bank card numbers.

3. Transfer-related content: when you actively select files, send clipboard content or receive files, such content is transferred between your device and the receiving device. We do not store transferred files, file content, clipboard text or transfer keys on our company servers.

4. Analytics information: we may collect app launches, feature usage frequency, page views, version information, device type, OS version, approximate region or anonymous user identifiers to analyze product performance, improve stability and optimize services.

5. Crash logs and diagnostics: when the Software encounters an error or crash, we may collect error stacks, error codes, device model, OS version, app version and network status to locate and fix issues. Such information should not include users’ files, clipboard content or transfer keys.

6. Push notification information: to send service status, purchase status, task completion, version updates or important notices, we may use system, vendor or third-party push services and process device push identifiers and notification status as necessary.

7. Apple information sync: if you choose to enable Apple or system-level information sync, the relevant synced content will be processed according to the sync scope you selected and the rules of Apple and other applicable platforms. This feature is not enabled by default.

3. Permissions

• Local network: used to discover and connect to other devices on the same local network.

• Files or storage: used only when you select files to send or save received files.

• Clipboard: read only when you actively trigger the clipboard sending function.

• Network access: used for sign-in, purchase verification, analytics, crash diagnostics and push notifications.

4. Sharing and Third-Party Services

We do not sell your personal information. To provide sign-in, purchase, analytics, crash diagnostics, push notification, information sync and other necessary functions, we may share information required for those functions with platforms or service providers such as Apple, Google, WeChat and others.

TRANSHI does not relay file or clipboard content through our company servers. To enable local network discovery, your device name, local network address and other necessary connection information may be visible to other devices running the Software on the same local network.

We may disclose relevant information where required by applicable laws or lawful requests from competent authorities, or where necessary to protect the lawful rights and interests of users, the Company or the public.

5. Retention and Security

Login information and purchase/subscription information are stored within mainland China and retained only for the period necessary to provide the services and meet legal requirements. Crash logs, analytics information and push notification information are retained for the period necessary for diagnostics, analysis or notification purposes, and then deleted or anonymized.

We use reasonable security measures such as access controls, encrypted transmission, permission management and log auditing. Please understand that no internet environment is absolutely secure, but we will use reasonable efforts to prevent unauthorized access, disclosure, damage or loss.

6. Your Rights

You may request access to, correction, copy or deletion of your personal information, account closure, withdrawal of consent, or an explanation of our personal information processing rules, subject to applicable law. Please contact us at official@kaichenera.com. We will respond within the period required by applicable law.

7. Minors

The Software is not directed specifically to children under the age of 14. If we discover that we have processed a child’s personal information without appropriate guardian consent, we will delete it or take other necessary measures as soon as reasonably practicable. Minors should use the Software with the consent of their guardians.

8. Updates to this Policy

We may update this Policy due to changes in laws, platform requirements or product functions. For material changes, we will provide notice in an appropriate manner. The updated Policy will take effect from the effective date indicated in the document.
