Privacy Policy

This Privacy Policy explains how personal information is handled by the mobile application provided by Yilian VPN (referred to as 'this Service' or 'we'). The Service is provided as is, and we take reasonable measures within this policy to protect user privacy and data security.

When you download and launch this App, the system may collect necessary operational data, including your IP address, device operating system version, in-app access paths, and session duration. To provide more accurate global connection services, we may process approximate device location information. This data is used to: 1. recommend connection options based on Yilian VPN's node distribution; 2. improve stability through anonymized aggregate connection trends; 3. send important service, security, or account notices through your registered email or username. Sensitive data is retained according to this policy.

We only transmit aggregated anonymized data to necessary third-party partners, such as Google Play Services and Firebase, to support crash analysis and feature improvement. We do not share personal information with third parties except when: 1. required by legal process or mandatory regulation; 2. necessary to protect user safety or investigate fraud; 3. working with service providers bound by confidentiality obligations. To stop new data collection, uninstall the App through the standard process on your device.

User-provided data is retained during the service period and for a reasonable grace period afterward. To cancel your account early and delete your profile, contact our privacy team at [email protected]. This App is not intended for children under 13. We do not knowingly request data from that group, and if such data is mistakenly collected, we will begin deletion procedures. We use reasonable physical, electronic, and administrative safeguards to protect data confidentiality.

This Privacy Policy may be updated from time to time for regulatory, operational, or product reasons. Please review this page periodically. Continued use after changes are posted will be treated as acceptance of the revised terms. This policy takes effect on October 4, 2025. For questions or suggestions about our privacy practices, contact the Yilian VPN team by email at [email protected].
