Privacy Policy

This Privacy Policy explains how Liuliangguang VPN ("we," "us," or the "Service") collects, uses, stores, and protects personal information when you access our mobile application and related services. We process data only where it is necessary to operate, secure, and improve the service, and we aim to explain those practices in clear language.

When you download, install, or launch the App, certain operational data may be collected so the service can function properly. This can include your IP address, device operating system version, in-app navigation paths, session duration, and approximate regional location. We use that information to: 1. Recommend more suitable connection routes based on node availability; 2. Identify stability issues through aggregated and anonymized diagnostics; 3. Send essential service notices, security alerts, or account-related communications. We try to limit collection to what is genuinely needed for service delivery.

We share information with third-party providers only where it is required to run, secure, or improve the service, such as Google Play Services or Firebase for crash analysis and diagnostics. Outside those limited cases, we do not disclose personal information unless: 1. Required by law, regulation, or legal process; 2. Necessary to protect the safety, rights, or property of users, the platform, or the public; 3. Handled by service providers bound by confidentiality obligations. If you want to stop future collection from the App, you can uninstall it using your device's standard removal process.

User-submitted information may be retained for the active service period and for a reasonable period afterward where needed for account management, dispute handling, or compliance obligations. If you want to delete your account data earlier, contact us at [email protected]. The App is not intended for children under 13, and we do not knowingly collect information from them. If such data is discovered, we will work to remove it promptly. We also apply access controls, system safeguards, and related security measures to reduce the risk of unauthorized access.

We may revise this Privacy Policy from time to time because of product changes, legal requirements, or operational updates. Please review this page periodically. Continued use of the service after a revision is published will be treated as acceptance of the updated policy. This policy is effective as of October 4, 2025. Questions about our privacy practices can be sent to [email protected].
