If you use AI Functions, please read this article carefully; if you do not use AI Functions, this article does not apply.

1. Users shall ensure they have lawful rights or authorization to the input content, and may not upload, input or provide:
   • content infringing third-party intellectual property, trade secrets or other lawful rights;
   • content breaching confidentiality obligations;
   • state secrets;
   • content violating the Master Contract;
   • content that may harm national security, public interests or cybersecurity;
   • personal information, trade secrets or third-party confidential information the user has no right to process or processes beyond authorization;
   • other content prohibited by laws and regulations.
2. The user understands and agrees that: Output is automatically generated by algorithms; Output may be similar to public information, third-party works or other users' generated content; other users may generate identical, similar or analogous content; such circumstances do not automatically mean Qicheng Intelligent has leaked data, made targeted disclosures or infringed trade secrets.
3. Except as expressly required by laws and regulations, Qicheng Intelligent does not guarantee that Output is original, non-infringing, absolutely accurate or complete, meets the user's specific needs, or is directly usable for production or commercial use.
4. Users shall review, verify and judge Output themselves and bear the risks and responsibilities arising from it.
5. You understand and agree that any Output generated by the Service, especially information constituting guarantees, offers or commitments, is automatically generated by algorithmic models without human intervention and may be fictitious or erroneous. Such content does not represent the company's true intent and does not constitute any legally binding offer or commitment to you or any third party. We will not perform or assume any Output automatically generated by the Service; to the extent permitted by law, we are not liable for any issues arising from reliance on such unofficial information.

You understand and agree that, in accordance with laws and regulatory requirements, Qicheng Intelligent may add explicit or implicit labels to some AI-generated, synthesized or assisted content, including text prompts, watermarks, metadata marks, system tags or other reasonable technical measures.Users may not delete, tamper with, hide or bypass such labels, or use the Service to generate or disseminate false information, misleading content or content that may confuse the public as prohibited by law.
7. To continuously improve the software's intelligent service capability, usability and quality, Qicheng Intelligent may conduct model optimization, algorithm evaluation, product improvement and service enhancement based on de-identified, anonymized, aggregated and statistical data.The user agrees that Qicheng Intelligent may, for the above purposes and in compliance with this Agreement, collect, use, store and otherwise process user data within a reasonable, necessary and minimal scope.Qicheng Intelligent understands the importance of data security and privacy and strictly follows these principles when processing user data:
   • Data anonymization: Qicheng Intelligent anonymizes data by removing identifiers such as enterprise names, product names, customer information, equipment numbers and employee information, ensuring data cannot be linked to the user's identity.
   • Data separation: System Data authorized for intelligent service processing is technically and logically separated from the user's raw Business Data. Any analysis or training on System Data will not affect the confidentiality, integrity or availability of raw user data.
   • Data security: Qicheng Intelligent uses dual "encryption + anonymization" technology to ensure data security. All data transmission uses encryption.
   • Compliant use: Qicheng Intelligent only shares data separately authorized by users through the Service or in writing with affiliates, partners and other parties where truly necessary, and will never sell raw user data to third parties or use it for commercial promotion or user profiling.
8. Notwithstanding any other provision of this Agreement to the contrary,the user agrees that Qicheng Intelligent may anonymize, aggregate and statistically process user data to generate System Data and, based on System Data, independently conduct within China a wide range of uses including model optimization, algorithm training, service enhancement, product improvement, industry trend analysis, technical validation and commercial application, without additional consent or payment.We undertake that the above processing will strictly comply with laws and regulations and ensure System Data contains no information that can identify you, determine your identity or reflect the user's specific business content. Except for performing the Service, troubleshooting, security governance, legal compliance or user authorization, Qicheng Intelligent will not proactively manually review, analyze or intervene in user-uploaded data.
9. Without separate explicit authorization, Qicheng Intelligent will not directly use user data for public general model training, nor proactively provide, disclose or reproducibly reconstruct a user's specific technical solution to other customers. Qicheng Intelligent will take reasonable technical and management measures to logically isolate different users' data and prevent data uploaded by a specific user from being directly retrieved, restored or reconstructed by other users.
10. Users may disable the "use data to improve experience" function in the Service; after doing so, user data will no longer be used for subsequent model optimization. However, users acknowledge that to maintain basic system operation and improvement and to comply with laws and regulations, they agree that Qicheng Intelligent may continue to use System Data to ensure secure operation of the Service and perform legal obligations.
11. Some capabilities may be supported by third-party model providers, cloud providers or partners. Users understand and agree that some data may be processed by such providers within the necessary scope; we will use contractual constraints and other means to ensure third parties comply with data security and confidentiality obligations no lower than this Agreement and prohibit them from using your data for any other purpose.
12. Personal information collected and generated by us within the People's Republic of China is stored on domestic servers.In principle, we do not provide your personal information overseas; if necessary, we will follow the Data Security Law, Personal Information Protection Law, Provisions on Promoting and Regulating Cross-Border Data Flows and other rules, through security assessment, standard contracts for cross-border personal information or certification, and inform you of the overseas recipient, purposes and methods, and how to exercise your rights, and obtain your separate consent.
