Terms of Use

1. Purpose and Scope

We provide download instructions, setup tutorials, and technical information for v2rayN, v2rayNG, and v2flyNG for educational purposes only. We are not the developers of these applications, and mentioning their names, interface terms, or procedures does not mean we represent their open-source projects.

These terms apply to articles, explanations, and on-site instructions published here. Clients, subscription services, and external websites may have separate terms, which you should review independently. Our technical information is not legal advice, nor does it guarantee or recommend any particular network environment, service, or configuration.

2. Lawful Use and User Responsibilities

Before using related software or technology, make sure your actions comply with the laws and regulations where you are located and in any applicable jurisdiction. Follow the rules of your employer, school, or network administrator. Do not use our content for unlawful purposes, unauthorized access, data theft, malware distribution, infringement of others' rights, or disruption of network operations.

Verify that your subscription source, node service, and intended destinations are lawful, and obtain any required authorization. Technical feasibility described in a tutorial does not grant permission to use a service. We do not sell subscriptions, share accounts, or provide node services. Users must resolve fees, authorization, and disputes relating to subscription services with the actual provider.

3. Configuration and Data Protection

Before changing subscription groups, routing, system proxy, or TUN settings, understand the potential impact and back up your existing configuration. Get permission from the administrator before making changes on work or shared devices or managed networks, and avoid disrupting connections for other apps or users.

Subscription URLs, access tokens, and client configurations may contain sensitive information; store them securely. Do not reveal complete credentials in public screenshots, logs, or feedback. Addresses and parameters in examples are for explaining formats only and should not be used as working service configurations. Before changing devices or uninstalling a client, save any needed configuration and remove sensitive data as appropriate.

4. Software Sources and Liability

The software mentioned here is provided by its respective open-source projects, which maintain its features, updates, compatibility, and bug fixes. We prepare our content using information available at the time of writing, but software interfaces, system permissions, and network conditions can change. We cannot guarantee that our instructions will always be complete, accurate, or suitable for every device.

To the extent permitted by applicable law, we do not guarantee the continued availability of any software or service. We are not liable for connection interruptions, data loss, device issues, or other losses caused by following tutorials, running third-party software, or changing configurations. Download links and external links do not constitute an endorsement or guarantee of the linked content or service quality.

Nothing in this section excludes or limits liability that cannot be excluded or limited by law. If a configuration behaves unexpectedly, stop the relevant operation, restore a known working setup, and use the logs to identify the cause. Avoid repeatedly applying parameters from unverified sources.

5. Intellectual Property and Open-Source Licenses

The names, logos, code, and documentation of v2rayN, v2rayNG, v2flyNG, Project V, V2Fly, Xray, and other projects belong to their respective rights holders. Use, modification, and distribution of the software must comply with the applicable project licenses and the licenses of included components. These terms do not replace or modify those licenses.

Our original tutorials and page content are protected by applicable law. When quoting them, credit the source. Do not distort their meaning, present them as official project documentation, or remove rights notices that must be retained by law. Permission to use third-party material is determined by its rights holder.

6. Changes to These Terms and Feedback

We may update these terms to reflect changes to our content, features, or legal requirements. Revised terms and the month of the update will be published on this page. Revisions apply to use from the date of publication onward. Where applicable law requires separate notice or consent, we will follow those requirements. We recommend reviewing these terms again before making significant configuration changes.

If you have questions about these terms or our instructions, see Frequently Asked Questions or the user guide. When reporting an issue, include the client, system environment, steps taken, and error details with sensitive information removed. If the relevant page offers a feedback form, you can submit your report there. We do not provide individual legal advice or resolve disputes involving third-party services.
