Terms of Service
Last updated: April 2026
These terms apply to the cross-border network access subscription service provided by S4VPN. Before using the service, please review its scope, account rules and refund policy. If you have questions, you can submit a ticket through the user panel. For information about personal data handling, see the Privacy Policy.
Service Scope
S4VPN provides access to international routes and subscription management, covering 100+ countries and 190+ routes, with support for Windows / macOS / iOS / Android / Linux. Route details shown in the user panel are authoritative. Coverage does not mean every route will always connect or that every third-party website will be accessible.
Get clients, access subscriptions and manage orders through the user panel. The service provides the network access entitlement included in your selected plan; it does not include accounts, content licenses or paid access on third-party platforms. Review plan prices and data rules on the Plans page and confirm them before placing an order.
Account and Subscription Rules
No email address is required; you can register with a username and password. Keep your login credentials and subscription link secure. Do not publish them or let others manage them on your behalf. If credentials are exposed or used unexpectedly, change your password promptly and submit a ticket for help securing your subscription credentials.
There is no limit on the number of devices that can be online at the same time, but accounts and subscriptions are for the account holder only. They may not be resold, rented, publicly distributed or shared with others. Unlimited devices does not mean unlimited data. Monthly subscription data resets each month on the activation date; upgrades made mid-cycle are prorated for the remaining days. Data packages remain available until used and do not expire.
Acceptable Use
When using the service, you must comply with the laws and regulations applicable where you are located, as well as the usage rules of the platforms you access. You may not use the service for fraud, infringement, distributing unlawful content, malicious attacks, unauthorized system access or any other unlawful purpose. You must not disrupt routes or other users’ normal use of the service.
You are responsible for assessing whether the content you access and your actions are lawful, and for activities carried out through your account. A successful network connection does not constitute authorization from a third-party platform. Disputes involving third-party accounts, content or transactions should be handled under that platform’s rules.
Availability and Liability
Your connection experience may be affected by your local network, carrier routing, destination websites, device configuration and maintenance. S4VPN performs necessary maintenance and route adjustments, but does not guarantee uninterrupted service, fixed speeds or continuous availability of any particular third-party service. Keep local copies of important work and an appropriate alternative connection method.
If you encounter a problem, submit a ticket with your device platform, error message and the circumstances in which it occurred. Do not include your password or full subscription link. S4VPN is not responsible for third-party policy changes, external network failures or device issues beyond its control. These terms do not exclude liability that applicable law does not permit to be excluded.
Payment and Refunds
You may request a full refund within 7 days of your first payment, for any reason. Sign in to the account used for payment and submit a request through the user panel ticket system, including order information that can be verified. You do not need to explain your reason for requesting a refund. Do not include sensitive credentials such as your payment password in a ticket.
Payments are supported via Alipay / WeChat Pay / USDT. Refund requests are handled after the order is verified. Updates on processing and refund arrangements will be provided through the ticket system; no unconfirmed arrival timeframe is promised. For disputes raised after the request period above, submit a ticket with details. They will be handled in accordance with applicable law and the circumstances of service delivery.
Account Termination and Changes to These Terms
If you use the service unlawfully, resell or share access, deliberately disrupt the service or otherwise materially breach these terms, S4VPN may restrict relevant features, suspend connections or terminate the account depending on the circumstances. Any measures taken should be proportionate to the risk. If you disagree with a decision, you may request a review through the ticket system. Orders and refund matters will be reviewed separately.
Changes to these terms will be published on this page, and the date at the top will be updated. Important changes to subscription entitlements will be announced on the site or through the user panel. Changes will not retroactively reduce statutory rights or existing refund commitments for orders already in effect. If you disagree with a change, you may stop using the service and submit a ticket to discuss how to handle any uncompleted orders.
