MatrixPost（“本扩展”）是一款内容多平台同步发布工具。我们把“登录态不出本机”作为架构红线。

我们收集什么

不收集。本扩展没有遥测上报、没有分析 SDK、没有广告标识符。所有数据（草稿、定时任务、平台账号信息、设置、发布回执、检测记录）都存储在你本机浏览器的 chrome.storage.local 中，卸载扩展即删除。

数据会去哪里（仅在你主动启用对应功能时）

  1. AI 改写 / AI 配图：仅当你点击使用且已自行填写 API Key 时，你选中的文本会发送给你自己配置的 AI 服务商（OpenAI 兼容接口）。我们与该服务商无任何关系，其数据处理见其隐私政策。不配置 Key 则此功能完全不发起任何网络请求。
  2. 云端中继：默认关闭。仅当你使用邮箱账号登录云端控制面后，扩展才会连接该服务器，且只传输你主动提交的发布内容（标题/正文/图片链接）与执行结果。
  3. MCP 桥接：默认关闭。仅监听本机回环地址（127.0.0.1），需登录邮箱账号授权，不暴露到局域网或公网。
  4. 网页抓取：仅在你对当前页面主动点击“抓取”时，读取该页面正文用于填入发布编辑器，内容不出本机。
  5. 互动数据采集：默认关闭。开启后，扩展按你设定的间隔访问你已发布内容的落地页（知乎 / 微博 / B 站 / 小红书），读取公开的阅读 / 赞同 / 评论数字，仅保存在浏览器本地用于趋势展示。该过程只读、不写入、不影响你的账号。
  6. 账号保活：默认关闭。按你勾选的平台与周期访问对应平台首页，等效于你手动打开一次页面以刷新登录态，不读取或存储任何 Cookie 内容。
  7. 问题反馈：仅在你主动提交反馈时，将你在反馈框中填写的描述与联系方式发送至 MatrixPost 云端用于诊断与回复，不附带任何浏览数据、账号数据或本机文件。
  8. AI 运营（订阅）：默认关闭。启用后，AI 按你的配置浏览公开页面、学习公开作品特征，并将匿名化的经验摘要（如封面构图规律、选题方向，不含你的账号标识与私密内容）上传云端经验池，用于改进全体用户的服务质量；可在设置中随时关闭，关闭后不再上传。

平台账号

本扩展通过你已登录的浏览器会话在各平台页面内完成填充与发布，从不读取、存储或传输任何平台的密码或 Cookie。

数据删除

扩展内“设置 → 清除数据”，或直接卸载扩展，即可删除全部本机数据。云端数据在云端服务器上，删除其 data.json 即清除。

English Version

MatrixPost ("the extension") is a multi-platform content publishing tool. "Login sessions never leave your machine" is an architectural red line.

What we collect

Nothing. No telemetry upload, no analytics SDK, no ad identifiers. All data (drafts, scheduled tasks, account info, settings, publish receipts) lives in your browser's chrome.storage.local and is deleted on uninstall.

Where data goes (only when you explicitly enable the feature)

  1. AI rewrite / AI images: only when you invoke the feature with your own API key, the selected text is sent to the AI provider you configured (OpenAI-compatible endpoint). We have no relationship with that provider. Without a key, the feature makes no network requests at all.
  2. Cloud relay: off by default. Only after you sign in to the cloud control plane with your email account does the extension connect to it, transmitting only the content you submit (title/body/image URLs) and execution results.
  3. MCP bridge: off by default. Listens on loopback (127.0.0.1) only, requires email-account authorization, never exposed to LAN or Internet.
  4. Page scraping: only when you click "scrape" on the current page; the extracted content stays on your machine.
  5. Engagement collection: off by default. When enabled, the extension revisits the landing pages of your published posts (Zhihu / Weibo / Bilibili / RedNote) on your chosen interval, reads the public view/upvote/comment counts, and stores them locally in your browser for trend display. The process is read-only and does not affect your accounts.
  6. Account keep-alive: off by default. Visits the home pages of the platforms you selected on your chosen schedule, equivalent to manually opening the page once to refresh your session. No cookie contents are read or stored.
  7. Problem reports: only when you voluntarily submit a report, the description and contact info you typed are sent to the MatrixPost cloud for diagnosis and reply. No browsing data, account data or local files are attached.
  8. AI Operations (subscription): off by default. When enabled, the AI browses public pages and learns from public works, and uploads anonymized experience summaries (e.g. cover composition patterns, topic directions — without your account identifiers or private content) to the cloud experience pool to improve the service for all users. You can disable it at any time in settings; nothing is uploaded after it is off.

Platform accounts

Publishing happens inside platform pages via your already-logged-in browser session. The extension never reads, stores, or transmits any platform password or cookie.

Data deletion

Use "Settings → Clear data" in the extension, or simply uninstall it, to delete all local data. Cloud-side data lives on the relay server and is removed by deleting its data.json.
