Privacy Policy

Effective: January 1, 2026 Last Updated: September 2026 Scope: AI Flashcard Maker Web App & Adaptive Learning Engine

1 Introduction & Privacy Commitment

AI Flashcard Maker ("we," "platform," or "our") deeply respects your privacy and the confidentiality of your academic materials. We are dedicated to protecting the personal data of students, educators, and lifelong learners worldwide.

This Privacy Policy explains how we collect, handle, store, protect, and process information and learning materials when you use AI Flashcard Maker. By accessing our website and study tools, you acknowledge that you have read and agreed to these terms.

2 Information We Collect

We strictly abide by the principle of Data Minimization. We only collect the minimal information necessary to generate smart study cards and power adaptive retention:

  • User-Provided Learning Materials: PDF documents, PPTX slides, Word files, text notes, YouTube URLs, or website links that you submit. These are used solely to extract concepts and generate flashcards and quizzes.
  • Local Learning Records & Progress Data: Generated card decks, card edits, spaced repetition (SRS) ratings (Again / Hard / Good), quiz scores, and match game records. These are stored locally in your browser's LocalStorage and are not silently collected to our servers.
  • Technical & Rendering Preferences: Browser type, viewport size, language preference (16 languages supported), and dark/light theme setting for seamless responsive rendering.

🔒 Local-First Privacy Architecture

AI Flashcard Maker is built with a local-first philosophy. Your decks, question edits, and memory proficiency scores live in your browser. You can export your data at any time as Anki decks, CSV files, or JSON datasets, retaining full sovereignty over your study history.

3 How We Use Information & Zero-Selling Policy

Information is processed strictly for the following purposes:

  • Generating Adaptive Study Decks: Analyzing uploaded materials to synthesize key concepts, definitions, multiple choice questions, true/false items, and written recall prompts.
  • Powering Cognitive Retention: Applying Active Recall and SM-2 Spaced Repetition algorithms to schedule timely reviews right before memory fades.
  • Multilingual Interface Delivery: Rendering interfaces and content in your selected language.
  • Platform Security & Abuse Prevention: Mitigating automated scraping and maintaining system stability.

Strict Commitment: We NEVER sell, rent, or trade your personal information, study notes, or uploaded documents to third-party data brokers or advertisers.

4 AI Processing & Foundation Model Policy

When you submit notes or documents to generate flashcards, the text is transmitted via encrypted HTTPS/TLS channels to our AI inference pipelines:

  • Ephemeral Processing: Uploaded notes are processed in memory to synthesize cards and returned immediately to your browser. Temporary processing states are promptly discarded.
  • No Unauthorized Foundation Model Training: Your private lecture notes, unpublished research, and classroom slides are NEVER used to train or fine-tune public foundation AI models without explicit consent.

5 Data Storage, Export & Permanent Deletion

You have full autonomy over your data:

  • Instant Export: Export your decks at any time to Anki TSV packages, Excel/CSV spreadsheets, JSON datasets, or formatted study notes.
  • Immediate Deletion: Clicking "Delete Card" or deleting a deck permanently purges that data from your local browser storage. Clearing browser cache also removes all local cards.
  • Erasure Requests: If you ever need assistance clearing any transient server connection logs, our compliance team is available to help.

6 Cookies & Local Storage

We do not use intrusive cross-site advertising cookies. We only use standard HTML5 LocalStorage to preserve your user preferences:

  • memoai_theme: Remembers your dark/light appearance mode;
  • memoai_lang: Remembers your chosen UI language preference;
  • memoai_active_deck: Caches your current active study deck locally.

7 Student & Underage Privacy (FERPA / COPPA)

AI Flashcard Maker is designed to meet international educational privacy standards. We do not collect government IDs, student identification numbers, or biometric data. Children under 13 may safely use the platform for study under the guidance of parents, guardians, or teachers.

8 Global Privacy Rights (GDPR & CCPA)

Whether you are located in the European Union (EU/EEA), California, the UK, or elsewhere, you possess full statutory rights to be informed, to access, to export (portability), and to erase your personal learning data.

9 Updates to this Policy

We may update this Privacy Policy from time to time to reflect product enhancements or regulatory changes. Significant changes will be prominently announced on our platform with an updated effective date.

1 引言与隐私承诺

AI Flashcard Maker(以下简称“我们”、“平台”或“本平台”)深知学习隐私与学术材料对用户的重要性。我们致力于保护每一位学生、教育工作者和终身学习者的个人隐私与数据安全。

本隐私政策详细说明了在您使用 AI Flashcard Maker 服务时,我们如何收集、使用、存储、保护以及处理您的个人信息和上传的学习材料。使用我们的网站及相关工具,即表示您已阅读并同意本政策的所有条款。

2 我们收集的信息

我们坚持“最小必要原则”(Data Minimization),仅收集向您提供高质量智能卡片制作与记忆训练所必需的信息:

  • 用户上传的学习材料(User-Provided Content):包括您提交的 PDF 文档、PPTX 课件幻灯片、Word 文档、TXT/Markdown 文本、课堂笔记、YouTube 视频链接或网页文章 URL。这些内容仅用于提取核心知识点、生成抽认卡与互动测试题。
  • 本地学习记录与进度数据(Local Learning Data):您生成的卡片组、卡片编辑修改、间隔重复打分记录(SRS 评级:生疏/困难/良好)、测验成绩和连连看历史等。默认完全保存在您本地浏览器的 LocalStorage 中,不会静默上传至云端服务器。
  • 技术与设备参数(Technical Metrics):包括浏览器类型、视口尺寸、界面多语言首选项(16 国语言标记)、深色/浅色主题偏好,用于提供响应式界面排版与视觉渲染。

🔒 本地优先架构(Local-First Commitment)

AI Flashcard Maker 采用本地优先架构。您的学习卡组、抽认卡编辑内容、记忆熟练度评分均保存在您的本地浏览器中。您可以随时通过导出功能将卡组完整下载为 Anki TSV、CSV 表格或 JSON 文件,数据完全归您自主掌控。

3 我们如何使用您的信息与绝不出售承诺

我们收集的信息严格用于以下特定目的:

  • 生成自适应学习卡片:利用 AI 模型解析您上传的文件内容,智能提取概念、定义、单选题选项、判断题及问答题。
  • 驱动科学记忆算法:根据认知心理学中的主动回忆(Active Recall)与间隔重复(Spaced Repetition)原理,计算复习推荐周期与测验反馈。
  • 多语言界面呈现:根据您的设备或手动选择,实时渲染 16 国主流语言的界面与卡片表达。
  • 平台安全与系统维护:诊断界面异常、防范恶意攻击及自动化滥用。

我们郑重承诺:绝不向任何第三方数据经纪商(Data Brokers)、广告商出售、出租或交易您的个人信息或个人笔记。

4 AI 处理与大语言模型策略

当您使用文档生成卡片功能时,相关文本段落将在受安全加密保护的传输管道(TLS/HTTPS)中提交给 AI 算力集群进行分块、概念萃取和题型合成:

  • 瞬态处理(Ephemeral Processing):AI 生成完成并将结构化卡组回传至您的前端后,临时处理数据即时释放。
  • 不用于公共模型无授权训练:您的私有讲义、独家学术笔记不会被用于公共基础大语言模型的训练集。

5 数据存储、导出与彻底删除权

我们赋予您对自身学习数据的完全掌控权:

  • 一键导出:您可以在工作区随时将卡组导出为 Anki 格式、Excel/CSV 电子表格、标准 JSON 格式或可打印的 Markdown 学习笔记。
  • 即时删除:点击工作区内的“删除卡组”或单个卡片的“删除”图标,数据将立即从您的本地存储中永久抹除。清除浏览器缓存亦可清除全部本地卡组。
  • 数据擦除请求:如需申请协助清理相关临时传输记录,可随时联系我们的数据合规团队。

6 Cookie 与本地存储技术

AI Flashcard Maker 不使用侵入性的跨站跟踪 Cookie。我们主要依赖标准 HTML5 LocalStorage 技术存储您的应用状态:

  • memoai_theme:记住您的深色/浅色视觉偏好;
  • memoai_lang:记住您选择的 16 国界面语言;
  • memoai_active_deck:缓存在本地浏览的活跃卡片组。

7 青少年与学生隐私合规(FERPA / COPPA)

AI Flashcard Maker 设计之初即符合全球教育隐私合规标准。平台不收集学生的身份证号、学校学籍号或人脸生物特征,未满 13 岁儿童在法定监护人或教师指导下即可安全用于课业温习。

8 全球用户权利(GDPR & CCPA)

无论您身处欧盟(EU/EEA)、美国加州、英国还是亚太地区,您均享有知情权、访问权、数据便携权以及更正/删除自身数据的法定权利。

9 隐私政策的更新

随着平台功能迭代和法律法规更新,我们可能适时修订本隐私政策。若发生重大变更,我们将在网站醒目位置发布通知,更新顶部的生效日期。
