Terms of Use

Last updated: August 2026

By accessing or using the v2flyNG Official Site, visitors confirm that they have read and understood these Terms of Use. The site provides V2Ray client download guidance, configuration tutorials, terminology explanations, and technical reference materials for software learning, technical research, and everyday configuration. Visitors who do not agree with any part of these terms must stop using the site and its related features.

1. Content Scope and Applicability

This site is a static reference resource for general users and people learning technology. It is not the developer, publisher, or commercial representative of v2rayN, v2rayNG, v2flyNG, V2Fly, Xray, or Project V. Client names, protocol names, interface descriptions, and configuration examples on these pages are provided to identify software and explain technical relationships. They do not indicate any authorized business, joint operation, or service commitment between this site and the corresponding projects.

The tutorials are compiled from publicly observable software behavior and common workflows. However, differences in versions, operating systems, and network conditions may affect menu names, permission prompts, or configuration results. Visitors should refer to the actual client interface and record existing settings before changing important options so they can restore them if necessary.

2. Lawful Use Requirements

Visitors must comply with all applicable laws, regulations, administrative requirements, and the rules governing the networks, devices, and services they use. Site content must not be used to gain unauthorized access to another person’s systems, bypass lawful authorization, disrupt network services, distribute illegal information, infringe privacy or intellectual property rights, or engage in any other harmful or unlawful activity.

Visitors must ensure that subscription URLs, server configurations, account information, and other connection details come from lawful sources and are properly authorized. They must not obtain, copy, publish, or transfer another person’s configuration without permission. Visitors are solely responsible for consequences arising from their own actions, the source of their configurations, or their intended use. The site may modify, restrict, or remove content that could encourage improper use.

3. Third-Party Software and External Resources

The software described on this site is provided by its respective open-source projects and maintainers. Release schedules, system compatibility, feature changes, licensing, and ongoing maintenance are determined by the corresponding projects. Download links may point to software files selected from a version list. Before installation, visitors should verify the platform, processor architecture, file name, and system requirements.

Third-party software, subscription services, node services, and external pages are not directly controlled by this site. When using these resources, visitors should also read the applicable provider’s license agreement, privacy rules, and usage requirements. A third-party resource moving, being suspended, having a version withdrawn, or changing its content does not obligate this site to continue providing an equivalent resource.

4. Limitation of Liability

The site strives to keep its page structure and technical explanations clear, but does not guarantee that all content will be current at all times or that any particular client, configuration method, or download link will remain available. Software updates, changes in system permissions, network differences, malformed subscription data, or user error may affect installation and connection results.

To the extent permitted by applicable law, the site is not liable for any direct or indirect loss resulting from the use or inability to use site content, third-party software, or related configurations, including but not limited to overwritten settings, data loss, service interruptions, device malfunctions, invalid subscriptions, or business disruption. Visitors should back up important data and decide whether to follow a tutorial based on the risks of their actual environment.

5. Intellectual Property and Fair Use

Rights to v2rayN, v2rayNG, v2flyNG, and the names of related cores, protocols, and projects belong to their respective rights holders. Open-source software code, documentation, and release files are governed by the open-source licenses stated by their respective projects. This site does not alter those licensing relationships. Anyone copying, modifying, or redistributing the software must comply with the applicable copyright notices, license conditions, and redistribution requirements.

The site’s original Chinese compilations, page layouts, and explanatory text are protected by applicable intellectual property laws. Reasonable quotation for personal study is permitted. Anyone reproducing a substantial portion of the content should clearly retain the source, must not create a misleading impression by removing or altering context, and must not imply an unconfirmed partnership with this site or any related open-source project.

6. Updates and Feedback

These Terms of Use may be revised as a result of page feature changes, legal developments, updates to the software ecosystem, or content maintenance. The revised version will be published on this page, and the last-updated month at the top of the page will be changed accordingly. Unless otherwise stated on the page, the new terms apply to visits and use occurring after publication.

Visitors should review this page regularly to stay informed about the currently effective terms. For questions about client installation, subscription import, proxy modes, or routing settings, first consult the configuration tutorials and the beginner-to-advanced handbook. These pages provide operational guidance and do not guarantee results in any particular environment.
