Privacy Policy

This Privacy Policy explains how the mobile application provided by Liuliangguang VPN (the 'App') collects, uses, and protects personal information. We process data according to principles of necessity, transparency, and security.

When you download and launch the App, the system may collect necessary operational data, including your Internet Protocol (IP) address, device operating system version, in-app paths, connection status, and session duration. To recommend suitable nodes and improve connection quality, we may process approximate device location information. This information is used for: 1. Node recommendation based on Liuliangguang VPN route availability; 2. Performance optimization through anonymized aggregate data; 3. Service communication such as security notices, service updates, or subscription reminders sent to your registered email or username.

We only transmit aggregated or anonymized data to necessary third-party service providers, such as Google Play Services and Firebase, for crash analysis, feature improvement, and basic statistics. We do not share personally identifiable information except when: 1. Required by legal process or regulation; 2. Necessary to protect users' life, property, or investigate fraud; 3. Working with entrusted service providers bound by confidentiality obligations. To stop data collection, uninstall the App through your device's standard process.

User-provided data will be properly kept during the service validity period and for a reasonable grace period thereafter. If you need to cancel your account early and delete your personal profile, please contact our privacy team via [email protected]. In addition, this App strictly prohibits use by minors under the age of 13. We will not intentionally solicit any data from this group, and upon discovering the mistaken collection of such information, we will immediately initiate permanent deletion procedures. Guardians are advised to contact us via the aforementioned email so that we can take necessary technical interventions. To ensure data confidentiality, we have deployed multiple layers of physical and electronic defense systems to safeguard your information security in all aspects.

This Privacy Policy may be updated from time to time due to regulatory requirements, product changes, or business adjustments. Please review this page regularly. Continued use after changes are published means you accept the revised policy. This policy takes effect on October 4, 2025. For questions or suggestions, contact the Liuliangguang VPN team at [email protected].
