Terms of Use
Last updated: September 2026
These terms apply to access to and use of v2ray4.com and its Simplified Chinese pages. By visiting this site, reading its documentation, or using a download link provided here, you confirm that you understand the boundaries described below. If you disagree with any part of these terms, stop using the pages and navigation links provided by this site.
1. Content Scope and Applicability
This site provides download links, installation guides, subscription configuration guidance, proxy scope explanations, and troubleshooting resources for graphical clients such as v2rayN, v2rayNG, and v2flyNG. Its content is intended for software learning, configuration reference, and technical explanation; it is not professional advice for any particular device, network environment, or use case.
Clients, proxy cores, and proxy configurations operate at different layers: the client manages configurations and the user interface, cores such as Xray or V2Fly handle connections, and settings such as the system proxy, an app's own proxy, and TUN determine how programs connect. Users should make independent judgments based on their actual system, application behavior, and configuration source, rather than treating general steps as fixed results that apply to every version.
2. Responsible Use Requirements
Users must comply with the laws and regulations applicable where they are located and to the relevant services, as well as network management rules, software license terms, and internal organizational policies. The content on this site must not be used for unlawful activity, unauthorized access to computer systems, disruption of network services, distribution of illegal content, infringement of another person's privacy or intellectual property, or circumvention of legally imposed access controls.
Users are responsible for the subscriptions, server configurations, routing rules, domain resolution settings, and consequences of their use. When configuration is provided by a third party, verify its source, authorization scope, and conditions of use first. Before changing system proxy, certificate, network interface, or firewall settings on an organization-managed, public, or otherwise managed network or device, obtain the necessary administrative permission.
3. Third-Party Software and External Services
The software described on this site is provided by the respective open-source projects and their maintainers. This site is not the developer of those software projects and does not represent them or guarantee version support, continued functionality, or compatibility. Download links help users choose a client by platform and system architecture; the software's features, license terms, release schedule, and support scope are governed by the corresponding project's actual materials.
Subscription services, servers, domain resolution, certificate issuance, and network access are typically provided by independent third parties. This site does not participate in transactions, account management, or data processing for those services, and cannot control their stability, availability by region, content policies, or service changes. Before using a third-party service, users should read its terms and privacy notice.
4. Intellectual Property and Content Attribution
The rights to the names, software code, interface elements, and related marks of V2Ray, Project V, V2Fly, Xray, v2rayN, v2rayNG, v2flyNG, and others belong to their respective rights holders and are governed by the applicable open-source licenses and other relevant rules. This site uses these names only to identify projects, explain technical relationships, and describe procedures; such use does not grant ownership of or exclusive authorization from any project.
The Chinese-language explanations, page structure, and illustrative content created by this site are protected by applicable law. When quoting them reasonably for learning, commentary, or technical discussion, retain the necessary attribution and avoid creating confusion about the source. Copying, modifying, or redistributing open-source code, software packages, or project documentation must comply directly with the license adopted by the relevant project; these terms do not replace that license.
5. Liability Limits and Use Risks
Technical documentation may differ because of operating systems, client versions, core capabilities, network environments, or changes to upstream projects. This site revises its explanations as part of its content maintenance, but does not guarantee that every page will always be complete, current, or suitable for a particular environment. Before changing the system proxy, routing, DNS, TUN, or local listening ports, users should understand the impact and preserve the original configuration so it can be restored.
To the extent permitted by law, this site is not responsible for unavailable software, configuration errors, interrupted connections, changes to third-party services, conflicts between device settings, business interruption, or data loss. Users are solely responsible for consequences arising from failure to comply with laws and regulations, software licenses, service terms, or organizational requirements. If the result differs from the documentation, first consult Frequently Asked Questions or review the configuration layers and application connection method using the Quick Start Guide.
6. Updates and Interpretation
This site may revise these terms to reflect changes to page features, project relationships, legal requirements, or content maintenance needs. Updated text will be published on this page, and the “Last updated” date at the top will be changed at the same time; no separate individual notice will be provided. Continued access to this site after an update means that users have read and accepted the revised terms.
Review this page again before downloading a client, quoting content from this site, or making substantial system changes. If any provision of these terms is found invalid or unenforceable, the remaining provisions will continue in effect to the extent permitted by applicable law. Section headings are provided for readability and navigation only and do not affect the meaning of the main text.
