Keyouyun Service Agreement 

Welcome to the products and services provided by Keyouyun.

Before completing registration or using Keyouyun products and services in any way, please carefully read and fully understand this Keyouyun Service Agreement (the “Agreement”). If you do not agree to any part of this Agreement, or cannot accurately understand Keyouyun’s interpretation of its terms, please stop the registration process and do not proceed. By registering as a Keyouyun user or using Keyouyun products and services, you represent that you have fully read, accepted, and agreed to comply with this Agreement in its entirety.

If any violation causes legal consequences, you shall independently bear all corresponding legal liability in your own name.

Keyouyun again reminds you to carefully read and fully understand each clause, especially those that limit or exclude liability, those on jurisdiction and governing law, and any separate terms for enabling or using a specific service. Clauses that limit or exclude liability will be highlighted in bold or other conspicuous form.

If you are under 18 years of age, please read this Agreement accompanied by your legal guardian.

I. Contracting Parties and Scope of the Agreement

1.1 This Agreement is a valid contract between you and Hunan Zhiliu Network Technology Co., Ltd. (“Keyouyun” or “we”) regarding your use of Keyouyun-related products and services. “Keyouyun” refers to the software products of Hunan Zhiliu Network Technology Co., Ltd. A “User” means a person who uses Keyouyun-related products and services (“you”). You must be a natural person, legal person, or other organization with full capacity for civil rights and civil conduct.

1.2 The services under this Agreement mean the products and services Keyouyun provides to users, including but not limited to internet value-added services, online media, e-commerce, and advertising (the “Services”).

1.3 This Agreement also includes any separate terms, business rules, and similar documents that may apply when you use Keyouyun products or services or make a top-up (collectively, “Separate Terms”). Once officially published, such content forms an integral part of this Agreement and you shall also comply with it. Your acceptance of any such business rules or Separate Terms constitutes your acceptance of this Agreement in full.

II. Account and Password Security

2.1 To use Keyouyun products or services, you need to register a Keyouyun account. Please keep your username and password safe, and ensure that you log out and leave the Keyouyun service through the proper steps at the end of each online session.

2.3 If you discover any unauthorized login to Keyouyun services with your account, or any other situation that may lead to theft or loss of your account, you are advised to notify the Keyouyun service operator immediately. You understand that any action taken by the operator in response to your request requires a reasonable time, and that such action may not prevent the occurrence or expansion of harm. The Keyouyun service operator shall not be liable therefor.
