Terms of Service

1. Acceptance and Scope

By registering, signing in, paying, downloading a client, or continuing to use any WangYuYun service, you confirm that you have read, understood, and accepted these terms.

These terms apply to the WangYuYun website, admin surfaces, the iOS, Mac, Windows, and Android clients, and the subscription, node, account-sync, and support services we provide.

We may revise these terms in response to legal, compliance, or service changes. We will notify revisions through the website or email. Continued use means you accept the new version.

2. Accounts and Credential Security

Please register with a valid email address, or bind an Apple or Google account, so you can receive sign-in codes, password resets, and important notices.

Keep your password, codes, and session tokens private. Actions taken from your account are treated as yours or as authorized by you.

If you notice unusual sign-in activity, lose a device, or suspect subscription abuse, contact support immediately via the in-client ticket system.

To protect your account we may require you to re-verify your email, third-party identity, or other necessary information.

3. Permitted Use and Prohibited Conduct

WangYuYun is for personal or household lawful internet access. Do not use the service for anything illegal, abusive, harassing, fraudulent, or for distributing malware.

Do not disrupt, reverse engineer, scan, stress-test, bypass, or interfere with our servers, clients, nodes, payment, authentication, or risk-control systems.

Do not mass-register accounts, resell access, scrape data, send spam, or automate abuse in any form.

For safety, stability, and compliance, we may rate-limit, temporarily block, or require re-verification on anomalous traffic.

4. Subscriptions, Traffic, and Devices

Each plan's node coverage, traffic quota, device limit, and add-on features are shown live on the purchase page and in your account center.

Subscription benefits are for the account holder and the devices you authorize. Reselling, renting, or large-scale sharing with strangers is not allowed. Clearly anomalous concurrency may trigger rate limits or temporary suspension.

You can view and manage authorized devices in your account center, and revoke unknown ones with one tap.

We send renewal reminders 7 days before expiry via in-app, email, or push. After expiry some premium benefits will pause until you renew.

5. Payment, Free Trial, and Refunds

We accept mainstream payment methods such as Alipay and WeChat Pay. Benefits activate immediately after successful payment.

New users receive a free welcome pack with a limited trial quota — no payment method required. The trial stops automatically at the end and no charge is incurred.

Paid plans are generally non-refundable mid-cycle unless we caused a major service failure or clearly breached our obligations. You can stop renewal at any time; your account and unused traffic remain valid until the period ends.

If the service is unavailable for a continuous 24-hour period, we will automatically extend your plan duration or negotiate equivalent compensation.

6. Availability, Maintenance, and Changes

Actual connection quality depends on region, carrier, device OS, node load, route conditions, and force majeure. We work to maintain stability but cannot guarantee 100% uptime on any individual node.

We perform regular upgrades, capacity expansion, security patches, and feature iteration. Major maintenance is announced in advance where possible; emergency maintenance may not be announced beforehand.

Features in staged rollout, beta, or preview may change in availability, performance, and interface at any time and are not a commitment to all users.

7. Intellectual Property

The WangYuYun website, clients, logo, copy, visual assets, code, and service architecture are owned by WangYuYun or our partners and are protected by copyright, trademark, and related laws.

You may not copy, modify, redistribute, reverse engineer, or build derivative products from the service without our written authorization.

Content you submit through tickets, feedback, or device logs may be used to improve the service, troubleshoot issues, and conduct data-safety audits.

8. Minors

WangYuYun is intended for users aged 18 and older with full legal capacity.

Minors may use the service only with the consent and supervision of a parent or guardian, who bears responsibility for actions taken under the account.

If we discover that an account is in fact used by a minor without guardian consent, we may suspend the service and proactively contact the guardian.

9. Suspension, Termination, and Liability Limits

If you violate these terms, create security risk, trigger abuse controls, refuse necessary verification, or harm other users' experience, we may limit, suspend, or terminate the relevant accounts, sessions, devices, or subscription benefits, and used fees will not be refunded.

To the maximum extent permitted by law, WangYuYun is not liable for indirect, incidental, or consequential losses caused by network conditions, third-party services, device OS limits, user misconfiguration, force majeure, or unauthorized account use.

For matters not covered here, we will handle them in good faith with fairness and user protection in mind.

10. Governing Law and Dispute Resolution

These terms are governed by the laws of the People's Republic of China (excluding conflict-of-laws rules).

Any dispute arising from these terms or use of the service should first be resolved by friendly negotiation. If negotiation fails, either party may file a lawsuit at the court with jurisdiction over the operating entity of WangYuYun.

11. Contact Us

Please submit any issue through the in-client "More → Tickets" page. Your account state, device, and diagnostic context are attached automatically, which helps support resolve issues quickly.

Tickets are answered within 24 hours; common issues are usually replied within 1 hour.

Feedback on these terms or on the service is also welcome via tickets — we take every response seriously.
