一句话总结：书签管理器 Pro（下称"本扩展"）是一个本地优先工具。开发者没有后端服务器、账号系统或分析服务；唯一的外部请求是生成网页预览截图（可一键关闭），以及你主动点击"检测失效链接"时的检测请求。
开发者不收集这些数据。本扩展没有后端服务器，开发者无法读取以下仅保存在你自己浏览器本地存储（chrome.storage 与 localStorage）中的信息：
书签本身由 Chrome 浏览器管理，本扩展只是读取和（在你操作时）修改它们。卸载本扩展后，上述本地数据会被 Chrome 自动清除，你的书签不受影响。
| 权限 | 用途 |
|---|---|
| bookmarks | 读取和管理你的 Chrome 书签——这是本扩展的核心功能（展示、搜索、移动、编辑、删除、排序）。 |
| storage | 在本地保存你的手动分类和界面偏好（见第 1 条）。 |
| favicon | 从 Chrome 本地的图标缓存读取网站图标用于展示，零网络请求。 |
| history | 读取最近 30 天的访问次数，用于"常用书签"排序——这样不论你从 Chrome 书签栏、地址栏还是本扩展打开书签，都会计入；另外从最近的搜索记录识别你在 Chrome 里设置的默认搜索引擎，用于在搜索栏显示它的图标、打开它的首页。查询在你本机完成，只用于上述两件事，不存储、不上传、不发送到任何服务器（本扩展没有服务器）。 |
| search | 把你在导航页网页搜索栏里输入的内容交给你在 Chrome 中设置的默认搜索引擎（与在地址栏搜索相同）。本扩展不读取、不保存搜索内容。 |
| chrome_url_overrides（新标签页） | 把新标签页替换为书签导航页，默认开启，可在导航页顶栏一键关闭（关闭后新标签页打开默认搜索引擎的首页）。 |
| 可选：所有网站 | 仅当你主动点击"检测失效链接"时申请，用于逐个访问当前范围内的书签网址。申请前会先说明用途；检测结束后立即收回。不点击该功能，此权限不会被申请。 |
网页预览默认开启。当书签卡片接近可视区域时，对应书签网址会发送给 WordPress.com 的公开截图服务 mShots（域名 s0.wp.com，由 Automattic 运营）以生成截图；结果缓存在你的浏览器本地。该服务受 Automattic 隐私政策约束。
如果你不希望发送任何书签网址：在导航页顶栏点击「预览：开」把它切换为「预览：关」即可完全停用，卡片变为纯文字。之后只有你另行主动启动"检测失效链接"时，扩展才会访问书签网址。
本扩展对从 Chrome API 获得的信息的使用遵守 Chrome 网上应用店用户数据政策，包括 Limited Use（有限使用）要求。
卸载本扩展即删除其全部本地数据（Chrome 自动完成）。你的书签是 Chrome 的数据，不会因卸载本扩展而改变。
如本政策有实质性变更，我们会在扩展更新说明和本页面中注明。任何疑问请联系：allenma2ong@gmail.com
In one sentence: Bookmark Manager Pro ("the Extension") is local-first. The developer has no backend, account system, or analytics service. The only external requests are preview screenshots (which you can switch off with one click) and the checks you start yourself with "Check dead links".
The developer does not collect this data. The Extension has no backend, so the developer cannot access the following information stored only in your browser's local storage (chrome.storage and localStorage):
Your bookmarks themselves are managed by Chrome; the Extension only reads them and modifies them when you act. Uninstalling the Extension removes all of the local data above (handled by Chrome); your bookmarks are unaffected.
| Permission | Why it's needed |
|---|---|
| bookmarks | Read and manage your Chrome bookmarks — the core purpose of the Extension (display, search, move, edit, delete, reorder). |
| storage | Save your manual categories and preferences locally (see section 1). |
| favicon | Show site icons from Chrome's local favicon cache — zero network requests. |
| history | Read visit counts from the last 30 days to rank "Frequent" bookmarks — so opens from Chrome's bookmarks bar, the address bar, or this extension all count; and to recognize the default search engine you set in Chrome from your recent searches, so the search bar can show its icon and open its homepage. The query runs locally on your machine and is used only for these two things: nothing is stored, uploaded, or sent to any server (the Extension has no server). |
| search | Send what you type into the grid's web search bar to the default search engine you set in Chrome (same as searching from the address bar). The Extension does not read or keep your searches. |
| chrome_url_overrides (new tab) | Replace the new tab page with the bookmark navigation page. On by default; one click in the grid header turns it off (new tabs then open your default search engine's homepage). |
| Optional: all sites | Requested only when you click "Check dead links", so the Extension can request each bookmarked URL to verify it still works. The Extension explains why before asking, and removes the permission as soon as the check ends. If you never use that feature, this permission is never requested. |
Page previews are on by default. As a bookmark card approaches the visible area, its URL is sent to WordPress.com's public mShots screenshot service (s0.wp.com, operated by Automattic) to generate the screenshot; the result is cached locally in your browser. The service is governed by Automattic's privacy policy.
If you'd rather send no bookmark URLs at all, click "Preview: On" in the grid header to switch it to "Preview: Off" — screenshot requests stop entirely and cards become text-only. The Extension will then contact bookmarked sites only if you separately start a dead-link scan.
The Extension's use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Uninstalling the Extension deletes all of its local data (Chrome handles this automatically). Your bookmarks belong to Chrome and are not affected.
Material changes to this policy will be noted in the extension's release notes and on this page. Questions: allenma2ong@gmail.com
