Terms of Use

Last updated: August 2026

By accessing or using the V2Ray Official Downloads website, visitors acknowledge that they have read and understood these terms. This site provides download guidance, installation steps, subscription configuration instructions, and troubleshooting resources for v2rayN, v2rayNG, and v2flyNG. Before proceeding, users should determine whether the information is suitable for their device, network environment, and intended use.

1. Content Scope and Applicability

The content on this site is provided for software learning, technical research, and general configuration reference. It does not constitute a professional guarantee for any specific device, network environment, or use case. The procedures described on these pages are based on publicly available versions and common operating-system environments. Client interfaces, option names, permission requirements, and core behavior may change as projects evolve; actual use should follow the current software interface and project documentation.

This site may include internal links to installer pages, user documentation, troubleshooting resources, and related articles. Information across different pages is intended to be read together and should not be interpreted by isolating a single passage from its context. Before changing system proxy, routing, DNS, or TUN settings, users should save important configurations and confirm that the changes will not affect running services.

2. Lawful Use and User Responsibilities

Users must comply with applicable laws and regulations in their jurisdiction, network service rules, organizational policies, and software license terms. They must not use this site’s materials, clients, or related configurations for illegal activities, infringe the lawful rights of others, or disrupt the normal operation of any network, device, or service. Responsibility arising from account permissions, subscription sources, node configurations, and actual network activity rests with the individual user.

Users should securely manage subscription URLs, server parameters, authentication details, and local configuration files, and should not disclose sensitive information to unrelated parties. When using related features on a company, school, or otherwise managed network, users must first confirm that such use complies with the network’s policies. This site does not determine whether a particular configuration is lawful or compliant in a specific jurisdiction or organization.

3. Software Sources and Service Boundaries

This site is not the developer or maintainer of v2rayN, v2rayNG, v2flyNG, V2Fly, or Xray. The relevant software and cores are provided and maintained by their respective open-source projects. Their features, release schedules, system compatibility, and future maintenance are determined by those projects. This site organizes download guidance and Chinese-language usage materials but does not control the content released by third-party projects.

This site may temporarily suspend some pages or download links due to maintenance, deployment changes, network failures, or changes to upstream resources. Documentation may also be revised as client versions change. This site does not guarantee that every page, link, or instruction will be accessible at all times, nor that any feature will suit every device. If you encounter installation, configuration, or connection issues, first review the troubleshooting steps in Troubleshooting or the user documentation.

4. Disclaimers and Limitation of Liability

Users must assess the risks themselves when using this site’s content to install, upgrade, uninstall, take over network traffic, or modify configurations. To the extent permitted by applicable law, this site is not liable for connection failures, lost configurations, data loss, service interruptions, or other direct or indirect effects caused by user error, system differences, permission restrictions, configuration conflicts, subscription issues, upstream service outages, or changes to third-party software.

This site makes reasonable efforts to organize its technical content but does not guarantee its absolute accuracy, continued validity, or suitability for any particular purpose. Examples in the documentation are provided only to explain field structures and operation sequences; they are not intended for direct use in every environment. Before working with production devices, important accounts, or critical networks, users should test changes in a recoverable environment and retain necessary system and configuration backups.

5. Intellectual Property and Open-Source Licenses

The names, source code, documentation, and marks associated with v2rayN, v2rayNG, v2flyNG, and their related cores belong to their respective rights holders and are used under the open-source licenses or other license terms published by each project. When downloading, copying, modifying, or distributing the software, users must read and comply with the applicable project licenses. The site’s descriptions do not grant any authorization beyond the scope of the original license terms.

The original Chinese explanations, page layouts, and instructional text on this site are protected by applicable law. Individuals may make reasonable quotations for learning and configuration purposes, but reproduced material must retain its complete meaning. Context must not be edited to create a false conclusion, and the material must not be presented as an official statement from any related open-source project. Product names appearing on these pages are used solely for identification and technical explanation.

6. Updates to These Terms and Continued Use

This site may revise these terms in response to changes in legal requirements, site features, the software ecosystem, or the scope of its content. Updated text will be published on this page, and the revision date will be shown by the Last updated month at the top of the page. Unless applicable law requires otherwise, revisions take effect when published without separate individual notice.

Users should review this page periodically before continuing to use the site. Continued access to downloads, tutorials, or other content after an update constitutes understanding and acceptance of the revised terms. If users disagree with any part of them, they should stop using this site and its materials. If a specific installation procedure or configuration detail is unclear, users should consult the site’s tutorials and frequently asked questions rather than act on an outdated page or an isolated passage removed from context.
