Terms of Use
These terms apply when you visit v2rayfirst.com, read its documentation, or use its client download links. Read the relevant information before proceeding. If you do not agree to the applicable conditions, stop using the relevant content or feature. These terms do not replace the software's own license agreement.
1. Content and Scope
This site brings together client introductions, installation steps, and configuration guides for the V2Ray ecosystem. Its content is for learning, technical research, and reference only; it is not legal or security advice, nor guidance for any specific business deployment. The site provides information and download links, not subscription accounts, servers, or network services.
Menus, paths, and examples in the documentation illustrate how to perform tasks. Interfaces and behavior may differ as software versions, operating systems, and configuration requirements change. Check the actual client prompts to determine what applies to your setup; do not use example snippets as production-ready solutions without review.
2. Lawful Use
You must comply with the laws and regulations that apply where you are and to your activities, as well as network-use requirements and your organization's device policies. Do not use this site's materials or related software for unlawful purposes, including unauthorized system access, data theft, network disruption, or infringement of others' rights.
Before using a client, make sure you are authorized to use the relevant devices, networks, and services, and follow the service provider's terms. A software feature being available does not mean its use is permitted in every situation. If you are unsure whether a particular use is lawful, consult a qualified professional first.
3. Software and Third-Party Services
v2rayN, v2rayNG, v2flyNG, and their associated cores are provided by their respective open-source projects. This site's name, descriptions, and links do not mean it represents those projects or that the project maintainers authorize, endorse, or warrant this site. Refer to the documentation accompanying each project for software features, license terms, and releases.
Clients operate independently of servers, subscriptions, and network environments. This site does not control third-party service charges, connectivity, content, or data handling. Review the terms and risks of any such service separately before using it. This site's documentation does not endorse third-party services.
4. Liability and Data Protection
To the extent permitted by applicable law, this site provides materials as is, without guaranteeing that they will always be complete, up to date, or suitable for a particular purpose. Nor does it guarantee the ongoing availability of software or related services. Connection failures and configuration issues caused by version differences, system settings, or third-party services must be addressed in light of your specific environment.
Back up your configuration and understand how to restore it before changing routing, DNS, system proxy, or TUN settings. Subscription URLs, sharing links, and configuration backups may contain access credentials; keep them secure and do not share them publicly. This site does not store or restore users' local configurations.
To the extent permitted by law, this site is not liable for data loss, business interruption, or indirect damages arising from the use of reference materials or related software. These terms do not exclude liability that cannot legally be excluded or limit any mandatory rights you have under applicable law.
5. Intellectual Property and Open-Source Licenses
Rights to each client, core, trademark, and project name belong to their respective owners. Open-source software remains protected by copyright. When using, modifying, distributing, or redistributing software, follow the license for the relevant version and retain copyright notices and other required information.
Text and page code written by this site are protected by applicable law. When quoting them, cite the source. Do not remove attribution and present the material as your own, or imply that the relevant projects endorse quoted content. This site's descriptions do not change the license terms of third-party materials.
