Overview. "EasyLearn" helps you look up concepts you select on a web page and save them into a local spaced-repetition review deck. You may either use your own API key (BYOK) or choose the optional free tier operated by the developer.
What is processed. When you trigger a lookup or ask a question, EasyLearn processes: (1) the concept or text you submit, (2) any surrounding sentence or paragraph you provide, and (3) any question you type. If you actively request a simpler explanation or example, EasyLearn may also send up to three locally selected concept names and short definitions that you previously reviewed. If you choose to look up a suggested concept, its name and a short explanation of its relationship to the source concept are sent as lookup context. The page URL and title are saved locally as source information but are not included in the model request.
BYOK requests. If you choose a third-party provider and enter your own API key, the selected text, context and question are sent directly from the extension to that provider solely to generate the requested explanation or answer.
Free-tier requests. If you choose the free tier, the selected text, context and question pass through an EasyLearn-operated Cloudflare Worker and are then sent to DeepSeek. The proxy builds a restricted task-specific prompt, applies anonymous-client and global rate limits, and is not designed to persist prompt or response content. Cloudflare and DeepSeek may process network and operational metadata under their own policies.
What stays on your device. The page title and URL where you performed the lookup are stored locally as source context for your saved concept and are not sent to the AI provider. Your saved concepts, contexts, notes, tags, automatic topics, manual folders, concept relationships, review schedule, and settings (including your API key) are stored locally in your browser via IndexedDB and chrome.storage.
What we do NOT do. We do not collect product analytics, track you across sites, sell your data, use it for advertising, or use model requests for purposes unrelated to the lookup and Q&A features.
Third-party processing. Text you send for explanation is processed by the AI provider you select, under that provider's own privacy policy. Please review the policy of whichever provider you use.
Retention & deletion. Local data remains in your browser until you delete individual items, restore another backup, or uninstall the extension. Full JSON backups are created only when you request one, may include your saved folders and concept relationships, and exclude your API key and anonymous rate-limit identifier.
API key. Stored locally and transmitted only to your chosen provider as the authorization credential for your own requests.
Children. This extension is not directed to children.
Changes. We may update this policy; the date above reflects the latest version.
概述。「EasyLearn 概念速查」帮助你在网页上划词查询概念，并沉淀为本地间隔重复复习库。你可以使用自己的 API Key（BYOK），也可以选择由开发者提供的免费版。
会处理的内容。当你发起查询或提问时，EasyLearn 会处理：(1) 你提交的概念或文本；(2) 你提供的所在句子或段落；(3) 你输入的问题。当你主动点击“说简单点”或“举个例子”时，EasyLearn 还可能发送最多三个由本地筛选出的、你曾复习过的概念名称和简短定义。当你选择查询一条联想概念时，该概念名称以及它与来源概念的简短关系说明会作为查询上下文发送。页面标题和网址仅在本地作为来源保存，不会放入模型请求。
自带 Key 请求。当你选择第三方供应商并填写自己的 API Key 时，划选文本、上下文和问题会由扩展直接发送给该供应商，仅用于生成你请求的解释或回答。
免费版请求。当你选择免费版时，划选文本、上下文和问题会先经过 EasyLearn 运营的 Cloudflare Worker，再发送给 DeepSeek。代理只构造受限制的业务 Prompt，执行匿名客户端和全局限流，不以持久化用户 Prompt 或回答为设计目的。Cloudflare 与 DeepSeek 可能依据各自政策处理网络及运行元数据。
仅保存在你本地的内容。你查询所在网页的标题与网址，仅作为概念的来源信息保存在本地，不会发送给模型供应商。你保存的概念、语境、批注、标签、自动主题、自定义分类、概念关系、复习进度与设置（含 API Key）均通过 IndexedDB 与 chrome.storage 存储在你本地浏览器中。
我们不会做的事。我们不收集产品统计分析，不跨站追踪你，不出售用户数据，不把数据用于广告，也不会把模型请求用于查询与问答之外的目的。
第三方处理。你发送用于解释的文本，由你所选供应商按其各自的隐私政策处理，请自行查阅该供应商的政策。
留存与删除。本地数据保留在浏览器中，直到你删除单条、恢复其他备份或卸载扩展。完整 JSON 备份仅在你主动操作时生成，可包含你保存的分类与概念关系，但不包含 API Key 与匿名限流标识。
API Key。仅本地保存，且仅作为你本人请求的鉴权凭证发送给你所选的供应商。
儿童。本扩展非面向儿童。
变更。我们可能更新本政策，顶部日期为最新版本。
