本隐私政策适用于本 Windows 桌面 AI 客户端软件(易成AI,以下简称“本应用”)。本应用严格遵循《中华人民共和国个人信息保护法》《网络安全法》《数据安全法》《生成式人工智能服务管理暂行办法》以及微软商店应用合规规范,旨在向用户清晰说明本应用的数据收集、使用、存储与保护规则。
本应用主打本地 AI 计算、本地知识库 RAG、本地数据存储,默认不上传用户文档、聊天记录、个人隐私数据至任何云端服务器。
1. 本地文件读取(仅用户主动授权)
当用户主动上传本地文档至知识库时,本应用仅在用户设备本地完成文档解析、文本分片、向量嵌入与知识库检索。本应用不会将用户文档、文件内容、企业资料上传至外网服务器。
2. 聊天数据与对话记录
所有聊天记录、会话内容、问答上下文均仅存储在用户本地电脑数据库,仅用于用户本地历史记录查看,不会主动上传、同步或对外泄露。
3. 模型与 AI 计算说明
本应用依赖开源 Ollama 本地大模型生态,所有 AI 推理、知识库问答、向量计算均在用户本地设备完成。应用本身不内置、不分发、不静默下载任何模型二进制文件,模型由用户自主选择、自主下载、自主管理。
4. 设备硬件信息(用于软件授权校验)
为实现软件授权绑定设备、校验内购购买凭证,本应用会读取本机硬件信息(CPU标识、网卡MAC地址),经哈希运算生成唯一设备标识(device_id)。
本应用提供付费增值功能,用于扩容本地知识库额度、解锁高级功能,所有付费能力使用微软商店应用内购(Microsoft Store In-App Purchase, IAP)实现。特此明确声明:
本应用面向全年龄段用户,不针对未成年人收集任何隐私信息,无诱导付费、无不良内容生成。
我们可根据法律法规与产品迭代适时更新本隐私政策,更新后将在应用公开页面生效,继续使用软件即视为认可最新政策。

This Privacy Policy applies to our Windows desktop AI application Yicheng AI. This software fully complies with Microsoft Store policies, Cybersecurity Law, Personal Information Protection Law and relevant AI generation regulations. All user data processing is local, private and secure.
This app focuses on local AI computation, local knowledge base RAG and local data storage. It will NOT upload user documents, chat history or private data to any cloud server by default.
When users actively upload local documents to the knowledge base, document parsing, chunking, embedding and RAG retrieval are processed locally on the user’s device only. The application will not upload user documents, files or enterprise materials to external servers.
Chat records and session data are only stored in the local database for user history viewing, and will not be uploaded, synchronized or disclosed externally.
AI Model Statement
This application uses open-source Ollama local AI technology. The app does not embed, distribute, or silently download any AI model binaries. Users download and manage models independently.
Hardware Information for License Verification
To bind software license to your device and validate Microsoft Store IAP purchases, this app reads local hardware information (CPU ID, MAC address). The raw data is hashed to generate an anonymous unique device identifier (device_id).
This application offers paid premium features to expand local knowledge base quota and unlock advanced functions. All payment capabilities are implemented via Microsoft Store In-App Purchase (IAP).
Users have the right to view, delete and clear all local data generated by the application.
This application does not collect minor personal information and has no harmful content or induced payment functions.
We may update this privacy policy to comply with laws and product iterations. Continued use of the application means acceptance of the latest policy.
If you have questions about privacy, compliance or data security, please contact us via email ecai@ystcinfo.cn.
