Dear User, thank you for choosing this software. Before using it, please carefully read this "User Service Agreement" (hereinafter referred to as the "Agreement"), paying special attention to the provisions that disclaim liability, and then decide whether to use it after understanding them. This Agreement contains several important clauses that affect your rights (please pay particular attention to the bolded parts). By downloading, installing, using, registering, logging in, posting content, or performing any other operation, you are deemed to have agreed to abide by all the terms of this Agreement, its ancillary rules, and system specifications. If you do not agree with the Agreement, we recommend that you stop using it to avoid potential disputes.

Special Notice: Using this application means you unconditionally accept the following, which carry the same legal effect:

1.1 Genuine License Requirement
This software may only be obtained through the official website and officially authorized partner platforms. It is forbidden to use cracked versions, trade accounts illegally, or download from unauthorized third-party channels. Software obtained from unofficial channels is not recognized by the official party, and no technical support or rights protection will be provided. If a user is found to be using illegal resources, measures such as content deletion, access restriction, or permanent account banning will be taken depending on the severity. Any disputes (e.g., rights conflicts, legal proceedings) and losses (e.g., data loss, financial damages) arising from the use of illegal resources shall be borne solely by the user, and the official party shall not be liable for compensation.

1.2 Service Optimization Mechanism
Based on operational needs, the platform may adjust service content and perform regular upgrades, reserving the right to optimize functions, add modules, and release version updates, while also carrying out necessary system maintenance (which may temporarily adjust services). After a new version is released, features of older versions may become invalid and will no longer be supported. To fully protect your rights and ensure a secure experience, you are advised to update to the latest version promptly to avoid missing features, compatibility issues, and potential risks.

2.1 Account Registration Instructions
(1) This APP allows guest mode for browsing basic content, but to access advanced features or full services, you must complete the account registration process in accordance with national internet information service management requirements.
(2) While complying with the platform's account usage rules, you may independently create an account through this APP and obtain the right to use it, officially becoming a registered user. If you choose to log in quickly via a third-party platform such as WeChat, the system, based on mutual authorization from both the third-party service provider and you, will obtain corresponding information according to the scope of information disclosure you have set on that third-party platform, in order to create a linked account for you. The information of this linked account will maintain a corresponding relationship with the third-party information you authorize to be disclosed.

2.2 Account Termination Clause
When any of the following circumstances occur, the platform has the right to reclaim account permissions based on operational management needs: including the platform ceasing service, the user seriously violating the service agreement/code of conduct/supplemental provisions, endangering public safety/harming public interests/infringing upon others' rights, violating regulatory requirements such as the "Administrative Measures on Internet Information Services," failing to fulfill contractual obligations, or as required by law.

2.3 Legal Nature of the Account
A registered account is the basic credential for the platform to identify user identities and provide targeted services, serving as a unique identifier. From the moment registration is completed, the user shall bear full legal responsibility for all actions performed under their account.

2.4 Account Security Responsibility
Users must ensure the security of their account information throughout the process, take necessary measures to prevent devices from being used by others, and strictly safeguard login credentials. All consequences resulting from password leaks or account theft due to improper personal safekeeping shall be borne solely by the user. Special note: Transferring accounts in any form (whether for payment or free of charge) is prohibited. Any legal liabilities arising from account recovery, cancellation, or misuse by third parties due to such violations shall be attributed to the user themselves.

2.5 Age Restriction and Guardianship Responsibility
If a user is under the age of 14, they must obtain explicit consent from their legal guardian and use this service under the guardian's supervision. Both the user and the guardian must fulfill relevant obligations in accordance with the law. If there is any misrepresentation of age, circumvention of guardian review, or fraudulent registration, the platform reserves the right to permanently cancel the account, and any legal consequences and property losses arising therefrom shall be borne solely by the user.

2.6 Account Information Management Rules
After registration, core information (such as the linked mobile phone number) cannot be modified, but personalized content such as nickname and avatar may be set independently by the user. Special attention is required: All displayed content is strictly prohibited from containing illegal or non-compliant information, personally insulting remarks, identity impersonation, misleading identifiers, content infringing on third-party rights, or commercial advertising materials. If the above provisions are violated, the platform may take measures such as requiring rectification within a time limit, temporary suspension, or service restriction, and the relevant responsibilities shall be fully borne by the user.

2.7 Commitment to Information Authenticity
Users are obligated to ensure that the identity information submitted is true, accurate, and up-to-date, and are prohibited from stealing others' identity information or engaging in multiple registrations to seek improper benefits. The platform may suspend/terminate services or restrict functions without liability for accounts with false, invalid, or incomplete information, or where there is reasonable suspicion of such. In case of violations, the platform will implement accountability measures such as order rejection, service deactivation, and account cancellation depending on the circumstances.

2.8 Account Disposal and Risk Assumption
Based on laws, regulations, or platform rules, we may impose usage controls on violating accounts (including access restrictions, temporary freezing, or permanent closure). Consequences such as communication interruption and data loss caused by such control measures are the user's responsibility. If restoration of use is needed, the registration process must be completed again; for defaulting accounts, the platform reserves the right to permanently deny access.

2.9 Your account will be cancelled and your information deleted or anonymized under any of the following circumstances:
(1) Violation of this Agreement or platform rules;

Responsibility for third-party activities lies with the organizers; the platform has indicated the source. The platform reviews activities but cannot guarantee absolute accuracy. Users may refuse participation or complain if they have doubts. Risks and losses from participating in third-party activities are borne by the user.
