Privacy Policy

This Privacy Policy explains how the mobile application provided by Liuliangguang VPN (the 'App') handles personal information. The service is provided as is, and we take reasonable steps to protect user privacy and account security.

When you download and launch the App, we may collect necessary operational data, including your Internet Protocol (IP) address, device operating system version, in-app paths, session duration, and error logs. To provide suitable route recommendations, we may process approximate device location. This data is used for: 1. node recommendations based on Liuliangguang VPN's network; 2. performance optimization through anonymized aggregate trends; 3. service communication through your reserved email or username for updates, security notices, or account messages.

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 security maintenance. We do not share personal information except when: 1. required by legal process or regulation; 2. necessary to protect users, property, or investigate fraud; 3. working with service providers bound by confidentiality obligations. You may stop new app-side data collection by uninstalling the App.

User-provided data is retained during the service period and for a reasonable retention period afterward. To cancel your account and delete personal profile data, contact our privacy team at [email protected]. The App is not intended for children under 13. If we discover that such data was collected by mistake, we will take steps to delete it. Guardians may also contact us through the same email. We use reasonable physical, electronic, and administrative safeguards to reduce unauthorized access risks.

This Privacy Policy may be updated due to regulatory requirements, product changes, or operational needs. Please review this page periodically. Continued use after changes are published means you accept the updated policy. This policy takes effect on October 4, 2025. Questions or suggestions about privacy handling can be sent to the Liuliangguang VPN team by email at [email protected].
