Cerebro Lite is a browser extension for managing Elasticsearch clusters: shards and nodes, documents, a REST console, snapshots, templates, lifecycle policies and cluster settings. It does not collect, transmit or sell any personal data, and it does not use analytics or tracking.
What the extension stores, only in your browser:
- Saved clusters: the names, addresses, color tags and read-only flags of the clusters you choose to save, and when you last connected to them, in the extension's local storage.
- Cluster credentials: the username and password, API key or bearer token you enter for a cluster. By default they are kept in the extension's session storage and are cleared when the browser is closed. If you tick "Remember on this device", they are kept in the extension's local storage until you remove the cluster (the host is added to the saved clusters so that it can be removed). They are stored unencrypted, like other extension data on your computer.
- Console content and history: the requests you write in the REST console, saved per cluster, and the last 50 requests you sent with their status codes. Requests that carry credentials or API keys, and request bodies over 64 KB, are not saved in the history. The requests are what you wrote, so they may contain query terms or document content. Removing a cluster deletes its console content.
- Display preferences: the theme, the interface language, the zoom, the auto-refresh interval and whether it is paused, the sort order, density and node role filter of the shard table, the columns you chose on the nodes and documents pages, the index you last opened on the documents page for each cluster, the commands you recently used in the command palette (they can contain index or node names), and the widths of split panes, in the extension's local storage. The theme and the language are also cached in the extension page's local storage, so that the page opens in the right theme and language without waiting for the extension storage.
Where data is sent: requests go directly from your browser to the cluster addresses you enter, and nowhere else. Exported documents are saved as a file on your computer by the browser; they are not uploaded anywhere. Credentials are only sent to the cluster they belong to, in the Authorization header. There is no Cerebro Lite server.
Permissions: the extension requests access to a cluster's host only when you connect to it, and you can revoke that access at any time in the browser's extension settings. The storage permission is used for the data listed above.
Removing data: remove a cluster on the connect page (its remembered credentials are deleted with it), or uninstall the extension to delete everything it has stored.

简体中文
Cerebro Lite 是一个管理 Elasticsearch 集群的浏览器插件：分片和节点、文档、REST 控制台、快照、模板、生命周期策略和集群设置。它不收集、不上传、不出售任何个人数据，也不做统计或跟踪。
插件保存的数据，只存在你的浏览器里：
- 保存的集群：你选择保存的集群名字、地址、颜色标签、是否只读和上次连接时间，存在插件的本地存储里。
- 集群凭据：你为集群填写的用户名密码、API Key 或 Bearer token。默认存在插件的会话存储里，关闭浏览器即清除；勾选“Remember on this device”后存在插件的本地存储里，直到你删除该集群（该主机会自动加入已保存的集群，方便删除）。凭据和其他插件数据一样，不加密保存在本机。
- 控制台的内容和历史：你在 REST 控制台里写的请求（按集群保存），以及最近发出的 50 条请求和它们的状态码。带凭据或 API Key 的请求、超过 64 KB 的请求体不进历史。这些请求是你自己写的，可能含查询条件或文档内容。删除集群时，它的控制台内容一起删除。
- 界面偏好：主题、界面语言、缩放、自动刷新间隔和是否暂停，分片表的排序、行密度和按角色筛选节点的选项，节点页和文档页选的列，文档页每个集群上次打开的索引，命令面板最近用过的命令（可能含索引名、节点名），以及分栏的宽度，存在插件的本地存储里。主题和语言还在插件页面的本地存储里缓存一份，页面打开时不用等插件存储就能用上正确的主题和语言。
数据发往哪里：请求由浏览器直接发往你填写的集群地址，不发往任何其他地方。导出的文档由浏览器存成你电脑上的文件，不上传到任何地方。凭据只放在 Authorization 头里发给对应的集群。Cerebro Lite 没有自己的服务器。
权限：插件只在你连接某个集群时申请访问该主机的权限，你可以随时在浏览器的扩展设置里撤销。storage 权限用于保存上面列出的数据。
删除数据：在连接页删除集群（连同记住的凭据），或卸载插件删除它保存的全部数据。
