Terms of Service

This agreement is a legal contract between you and Quanqiu VPN (referred to as the 'Service Provider') regarding the downloading, installation, and use of the mobile network service application (referred to as the 'App').

By downloading, installing, or using the App, you confirm that you have read and agreed to this agreement. You may not copy, modify, reverse engineer, extract source code, translate app text, or create derivative versions without authorization. Intellectual property rights in the App, related trademarks, interface, and content belong to the Service Provider or its licensors. To maintain service quality, we may adjust features, routes, plans, or fees and will provide reasonable notice where appropriate. Users are responsible for device security and account credentials; jailbreaking, rooting, or installing unknown software may cause the App to malfunction or create security risks.

This Service integrates some necessary third-party services (such as Google Analytics, Firebase Crashlytics, etc.). During use, you are simultaneously bound by the respective terms of service of these partners.

Explanation of service limitations: The functionality of this App relies on a stable network environment (Wi-Fi or mobile data). If the service cannot be used due to user device arrears, data limits, or poor network signals, the Service Provider assumes no related responsibility. When used outside of a Wi-Fi environment, your mobile carrier may incur data traffic charges. If you enable roaming outside your country of origin without using a suitable data plan, the resulting roaming charges must be borne by you. Before using this App, please ensure you have obtained permission from the bill payer.

Users must bear full responsibility for their usage behavior. For example, if the service cannot be accessed due to device battery depletion, it is not covered by our compensation. Although we strive to provide the most accurate global routing information, some data comes from third-party partners; we do not bear legal responsibility for any direct or indirect losses resulting from this. To ensure compatibility and security, this App will irregularly release version updates, and you agree to download and install the latest versions when necessary. The Service Provider reserves the right to terminate the services of this App without prior notice. After service termination, the usage license granted to you will become invalid, and you must stop using and delete this App.
