Privacy Policy for AI Language Learning Expert

1. Introduction "AI Language Learning Expert" (hereinafter referred to as "the Extension") is a browser extension designed to create an immersive language learning environment. We value your privacy and are committed to transparency regarding how we assist your learning journey. This Privacy Policy explains our data practices.

2. Data Collection and Usage The Extension operates primarily on a "Local-First" architecture. We do not maintain a proprietary server to harvest your personal information, browsing history, or learning data.

A. Intelligent Content Analysis

• Feature Scope: When you utilize features such as "Immersive Translation," "Sentence Parsing," "Full Page Summary," "Word Look-up," or "Screen OCR," the Extension processes the specific text or visual area you are focusing on.

• Text Data Processing: Selected text is securely transmitted to DeepSeek, our core AI infrastructure provider, solely to generate high-quality linguistic explanations, translations, and study notes.

• Image Data Processing (OCR): When you trigger the "Screen OCR" feature, the Extension captures a temporary screenshot of the visible tab area. This image is processed entirely locally within your browser using Tesseract.js (WebAssembly) to extract text. The screenshot data is processed in memory and is never transmitted to our servers or any third party.

• Local Processing: Features like "Reader Mode" utilize local algorithms (Readability.js and DOMPurify) to declutter webpages directly within your browser, ensuring no data leaves your device for visual formatting.

B. Personalized Learning Data

• Storage: Your learning assets—including highlighted vocabulary, study notes, and custom configuration—are stored locally using the browser's chrome.storage.local and localStorage.

• Usage: This data remains on your device to facilitate features like:

  • Contextual Recall: Restoring highlights when you revisit a study material.

  • Performance Cache: Caching dictionary definitions and site icons locally to speed up your workflow and reduce network requests.

• Data Sovereignty: You can export your entire vocabulary history to a local .txt file at any time.

C. Authentication Credentials

• API Keys: To access premium AI capabilities, the Extension requires your personal DeepSeek API Key. This key is encrypted and stored locally. It is never transmitted to us or any unauthorized third party.

3. Integrated Learning Ecosystem & Third-Party Services The Extension functions as a central hub, connecting you with various educational services to build a comprehensive learning ecosystem. By using the Extension, you interact with the following providers:

A. Core AI Engine

• Service: DeepSeek API

• Purpose: The "brain" behind the Extension, providing natural language understanding and generation for chat, translation, and parsing.

• Privacy: Text data sent to DeepSeek is subject to DeepSeek's Privacy Policy.

B. Visual Interface Services

• Service: DuckDuckGo Icon Service; Jurieo Icon Service

• Purpose: To visually organize your learning tools, the Extension fetches favicons (website icons) for your configured resources via DuckDuckGo (e.g., icons.duckduckgo.com) or the Jurieo Proxy Service (e.g., gs.jurieo.com). To address cases where DuckDuckGo fails to retrieve specific site favicons, we have integrated Jurieo.com as a supplementary provider.

• Privacy: This process involves a standard GET request which may expose your IP address and the hostname of the tool you are adding to DuckDuckGo and Jurieo.

C. External Knowledge Bases & AI Tutors (User-Configured)

• Service: Custom Learning Resources

• Description: The Extension allows you to integrate external Knowledge Bases (e.g., online dictionaries like Collins, Youdao) and AI Tutoring Platforms (e.g., ChatGPT, Gemini) into the sidebar for quick access.

• Usage: When you use the "Quick Jump" or "Search" features, the Extension redirects your query to these platforms.

• Privacy: Once you navigate to these external platforms, your interactions are governed by their respective privacy policies.

D. Text-to-Speech (TTS)

• Service: Browser Native Speech Synthesis

• Purpose: To provide pronunciation for words and sentences.

• Privacy: This feature utilizes the native capabilities of your browser. Depending on your browser settings, text may be processed locally or by your browser vendor's speech service.

4. Permissions Usage We request specific permissions solely to enable essential learning functionalities:

• Storage: To persist your vocabulary lists, API keys, and custom interface settings locally.

• Host Permissions (<all_urls>): To activate the "Learning Sidebar" and "Smart Highlight" overlay on any webpage you choose to study. The Extension remains dormant until you actively trigger a feature.

• ClipboardWrite: To facilitate the "Auto-Copy" feature, streamlining your note-taking process.

• ActiveTab: To analyze the current article content for summarization or reading optimization.

• Scripting: To dynamically inject the "Learning Sidebar," "Smart Popup," "Reader Mode" interface, and the OCR engine (Tesseract.js) into the current webpage only when you explicitly activate these features. This ensures minimal impact on page performance and privacy.

5. Data Security All communications between the Extension and the integrated AI services occur over encrypted HTTPS channels. Since your sensitive data (API keys, learning history) is stored locally on your device, you retain full ownership and control.

6. Updates We may update this policy to reflect enhancements in our learning features. Significant changes will be communicated through the extension's update notes or settings panel.

7. Contact Us For inquiries regarding your learning data or this policy, please contact us at: 42118267@qq.com or lethe123@gmail.com.

AI 语言学习专家（AI Language Learning Expert）隐私政策

1. 简介

“AI 语言学习专家”（以下简称“本扩展”）是一款旨在打造沉浸式语言学习环境的浏览器扩展程序。我们非常重视您的隐私，并致力于在协助您学习的过程中保持数据处理的透明度。本隐私政策旨在说明我们的数据处理实践。

2. 数据收集与使用

本扩展主要基于“本地优先”架构运行。我们不维护专有服务器来收集您的个人信息、浏览历史或学习数据。

A. 智能内容分析

• 功能范围： 当您使用“沉浸式翻译”、“句子解析”、“全文摘要”、“划词查询”或“屏幕 OCR”等功能时，本扩展会处理您关注的特定文本或视觉区域。

• 文本数据处理： 所选文本将安全地传输至我们的核心 AI 基础设施提供商 DeepSeek，仅用于生成高质量的语言解析、翻译和学习笔记。

• 图像数据处理 (OCR)： 当您触发“屏幕 OCR”功能时，扩展会截取当前可见标签页区域的临时截图。该图像完全在您的浏览器本地使用 Tesseract.js (WebAssembly) 进行处理以提取文本。截图数据仅存储在内存中，绝不会传输至我们的服务器或任何第三方。

• 本地处理： “阅读模式”等功能利用本地算法（Readability.js 和 DOMPurify）直接在浏览器中净化网页，确保没有任何数据为了视觉格式化而离开您的设备。

B. 个性化学习数据

• 存储： 您的学习资产——包括高亮生词、学习笔记和自定义配置——均使用浏览器的 chrome.storage.local 和 localStorage 存储在本地。

• 用途： 这些数据保留在您的设备上，以支持以下功能：

  • 语境回溯： 当您再次访问学习材料时恢复高亮显示。

  • 性能缓存： 在本地缓存字典定义和站点图标，以加速工作流并减少网络请求。

• 数据主权： 您可以随时将完整的词汇历史记录导出为本地 .txt 文件。

C. 身份验证凭据

• API 密钥： 为了访问高级 AI 功能，本扩展需要您的个人 DeepSeek API Key。该密钥经过加密并存储在本地。它绝不会传输给我们或任何未经授权的第三方。

3. 集成学习生态系统与第三方服务

本扩展作为一个中心枢纽，连接各种教育服务以构建全面的学习生态系统。使用本扩展即表示您将与以下提供商进行交互：

• A. 核心 AI 引擎：

  • 服务： DeepSeek API

  • 目的： 作为扩展的“大脑”，为对话、翻译和解析提供自然语言理解与生成支持。

  • 隐私： 发送至 DeepSeek 的文本数据受 DeepSeek 隐私政策的约束。

• B. 视觉界面服务：

  • 服务： DuckDuckGo 图标服务；Jurieo 图标服务

  • 目的： 为了直观地管理学习工具，本扩展通过 DuckDuckGo (icons.duckduckgo.com) 或 Jurieo 代理服务 (gs.jurieo.com) 获取您配置资源的网页图标（Favicons）。针对 DuckDuckGo 无法获取部分站点图标的情况，我们集成了 Jurieo.com 作为补充提供商。

  • 隐私： 此过程涉及标准的 GET 请求，可能会向 DuckDuckGo 和 Jurieo 暴露您的 IP 地址以及您正在添加的工具的主机名。

• C. 外部知识库与 AI 导师（用户自定义）：

  • 服务： 自定义学习资源

  • 描述： 本扩展允许您将外部知识库（如柯林斯、有道等在线词典）和 AI 辅导平台（如 ChatGPT、Gemini）集成到侧边栏以便快速访问。

  • 隐私： 一旦您跳转到这些外部平台，您的交互将受其各自隐私政策的约束。

• D. 语音合成 (TTS)：

  • 服务： 浏览器原生语音合成

  • 目的： 为单词和句子提供发音。

  • 隐私： 此功能利用浏览器的原生能力。根据您的浏览器设置，文本可能由本地处理，也可能由浏览器厂商的语音服务在线处理。

4. 权限使用说明

我们请求特定权限仅为了实现核心学习功能：

• Storage (存储)： 用于在本地持久化存储您的词汇表、API 密钥和自定义界面设置。

• Host Permissions (主机权限 <all_urls>)： 用于在您选择学习的任何网页上激活“学习侧边栏”和“智能高亮”遮罩。本扩展在您主动触发功能前保持静默状态。

• ClipboardWrite (剪贴板写入)： 用于支持“自动复制”功能，简化您的笔记流程。

• ActiveTab (活动标签页)： 用于分析当前文章内容，以进行摘要提取或阅读优化。

• Scripting (脚本注入)： 仅在您明确激活功能时，向当前网页动态注入“学习侧边栏”、“智能弹窗”、“阅读模式”界面及 OCR 引擎 (Tesseract.js)。这确保了对页面性能和隐私的影响降至最低。

5. 数据安全

本扩展与集成 AI 服务之间的所有通信均通过加密的 HTTPS 通道进行。由于您的敏感数据（API 密钥、学习历史）存储在本地设备上，您拥有完整的所有权和控制权。

6. 更新

我们可能会更新本政策以反映学习功能的增强。重大变更将通过扩展程序的更新说明或设置面板进行通知。

7. 联系我们
