Privacy Policy

This Privacy Policy explains how the mobile application provided by Kuailian VPN (the 'App', 'this Service', or 'we') handles personal information. We process data to provide stable and secure connection services and to protect your privacy within the scope of this policy.

When you download and launch the App, the system collects operational data required for service delivery, including but not limited to your Internet Protocol (IP) address, device operating system version, in-app access paths, and session duration. To recommend suitable connection options, we may process approximate geographic location information. This data is used to: 1. recommend routes based on Kuailian VPN's node distribution; 2. improve network stability through anonymized aggregate analysis; and 3. send necessary service, security, or account notices to your reserved email or username. Sensitive information is retained in accordance with this policy.

We only transmit aggregated anonymized data to necessary third-party providers, such as Google Play Services and Firebase, for crash analysis and feature improvement. Except in the following cases, we do not share personal information with third parties: 1. compliance with legal process or mandatory regulatory requirements; 2. protection of user life, property, or fraud investigation; 3. cooperation with entrusted service providers bound by confidentiality obligations. To stop data collection, uninstall the App through the standard process on your device. After uninstallation, the App will not generate new collection activity.

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 or service changes. Please review this page periodically. Continued use after updates are published means you accept the revised terms. This policy takes effect on October 4, 2025. If you have questions about privacy processing, contact the Kuailian VPN team by email ([email protected]).
