Terms of Service

This agreement is a legal contract between you and Kuailian VPN (the “Service Provider”) governing the download, installation, and use of the App and related services.

By downloading, installing, or using the App, you agree to this agreement. You may not copy, modify, reverse engineer, decompile, or create derivative works from the App without authorization. All intellectual property rights in the App and related materials belong to the Service Provider.

The service may integrate necessary third-party capabilities such as analytics, crash reporting, or payment support. When using those capabilities, you may also be subject to the relevant third-party terms.

The App depends on an available network connection. If service quality is affected by device arrears, data limits, poor connectivity, or roaming charges, those costs and limitations remain the user’s responsibility.

You are responsible for maintaining the security of your device and account credentials. To preserve compatibility and security, we may update the App or adjust service content without separate notice. If the service is discontinued, you must stop using and delete the App.

These terms may be updated from time to time, and changes take effect on publication (Current effective date: October 4, 2025). If you have questions regarding Kuailian VPN terms, please contact support@kuailianfree.org.
