Dear User, thank you for choosing this software. Before using, please be sure to read this "User Agreement" (referred to as the "Agreement"), paying special attention to the liability exclusion clauses, and make your own decision whether to use it after understanding them. This Agreement contains several important provisions that affect your rights (pay particular attention to the bolded parts). By downloading, installing, using, registering, logging in, publishing content, or performing any other operation, you are deemed to have agreed to comply with all the terms of this Agreement, the supporting rules, and system specifications. If you disagree with the Agreement, it is recommended that you do not use it to avoid disputes.

Special Note: Using this application constitutes unconditional acceptance of the following content, which has the same legal effect:

1.1 Genuine Authorization Specification
This software is only permitted to be obtained through the official website and officially certified partner platforms. The use of cracked versions, illegal account trading, or downloading from unauthorized third-party channels is prohibited. Software obtained from unofficial channels is not officially recognized, and technical support or rights protection will not be provided. If a user is found using illegal resources, measures such as deleting content, restricting, or permanently banning the account will be taken depending on the circumstances. Any disputes (such as rights conflicts, legal proceedings) and losses (such as data loss, economic losses) arising from the use of illegal resources shall be borne solely by the user, and the official party shall not be responsible for compensation.

1.2 Service Optimization Mechanism
The platform will adjust service content and perform regular upgrades based on operational needs, reserving the right to optimize functions, add modules, and iterate versions, while also performing necessary system maintenance (which may temporarily adjust services). After a new version is released, the functions of older versions may become invalid and will no longer be maintained. To ensure complete rights and a secure experience, users are advised to update to the latest version promptly to avoid missing functions, compatibility issues, and potential risks.

2.1 User Account Registration Instructions
(1) This APP allows guest mode to browse basic content, but to use advanced functions or the full service, users must complete the account registration process in accordance with national internet information service management requirements.
(2) Under the premise of complying with the platform's account usage specifications, users can 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 through third-party platforms such as WeChat, the system, based on dual authorization from the third-party service provider and the user, will simultaneously obtain corresponding information according to the scope of information disclosure you have set on the third-party platform 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 for disclosure.

2.2 Account Termination Clause
When any of the following situations 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/supplementary 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 situations required by law.

2.3 Legal Nature of 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 completion of registration, the user shall bear full legal responsibility for all operational actions under their account.

2.4 Account Security Responsibility
Users must ensure the security of account information throughout the process, take necessary measures to prevent devices from being used by others, and strictly keep login credentials confidential. All consequences arising from password leakage and account theft due to improper personal safekeeping shall be borne solely by the user. Special Note: Transferring accounts in any form (paid or unpaid) is prohibited. 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 their supervision. Users and their guardians must fulfill relevant obligations in accordance with the law. If there are acts of misrepresenting age, bypassing guardian review, or registering through fraudulent means, 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 Specifications
After registration is complete, core information (such as the linked mobile phone number) cannot be modified, but personalized content such as nickname and avatar can be set independently by the user. Special attention must be paid to: 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 promotional information. If the above provisions are violated, the platform may take measures such as requiring rectification within a time limit, temporary banning, or suspending services, and the relevant responsibilities shall be fully borne by the user.

2.7 Information Authenticity Commitment
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 take measures such as suspending/terminating services or restricting functions without assuming responsibility for accounts with false, invalid, or incomplete information, or where there is reasonable suspicion of such. For 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 implement usage permission controls on violative accounts (including access restrictions, temporary freezing, or permanent closure). Consequences such as communication service interruption and data loss caused by control measures are the responsibility of the user. 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 information deleted/anonymized in any of the following circumstances:
(1) Violation of the agreement or rules;
(2) APP operation ceases;

5.3 The platform promotes self-operated, cooperative, or third-party activities. Users must read the details before participating independently. 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.

6.1 Agreement Revision

Please check for updates regularly (recommended monthly) via the APP (Settings -> About Us -> Agreement Update) or the official website.
