Privacy Policy
Clawser Browser Relay does not collect, store, or transmit any personal information or browsing data. It contains no telemetry, no analytics, and no crash reporting, and it does not communicate with any remote server.
1. How the extension works
Clawser Browser Relay is a developer tool. It exposes browser automation capabilities to a program that you run on your own computer (the Clawser client), in the same way that tools such as Puppeteer and Playwright do.
All communication happens inside your own machine. The extension connects only to
127.0.0.1, the loopback address of your computer. It makes no network
requests to any external host.
2. What the extension can access
Once you explicitly attach a tab to an automation session, the extension can read that page's content and perform actions on it through the Chrome DevTools Protocol.
- The extension acts only on tabs you have explicitly attached. It never attaches to a page on its own.
- Page content is passed only to the Clawser client running on your own computer. No third party is involved.
- What happens to that content afterwards is determined entirely by the scripts you write and run. The extension plays no part in it.
3. Local storage
The extension stores only its connection settings in your browser's local storage — the local relay port number and related preferences. No browsing data is stored. Uninstalling the extension removes all of it.
4. Permissions
- debugger
- Controls the tabs you attach, via the Chrome DevTools Protocol.
- Access to all websites
- Clawser is a general-purpose automation tool. The sites it operates on are chosen by you at runtime and cannot be known in advance, so a fixed list of hosts is not possible. The extension performs no background activity on any site.
- tabs / activeTab
- Lists open tabs so you can choose which one to attach, and reports tab state back to your local script.
- storage
- Saves the local relay port and connection preferences.
- alarms
- Schedules reconnection to the local relay after the service worker is suspended by the browser.
- webNavigation
- Detects navigation in attached tabs so the automation session stays synchronised.

Clawser Browser Relay 不收集、不存储、不传输任何个人信息或浏览数据。 本扩展没有任何遥测、分析或崩溃上报功能，也不与任何远程服务器通信。
一、扩展如何工作
本扩展是一个开发者工具。它在你的电脑上，把浏览器自动化能力提供给你自己运行的本地程序 （Clawser 客户端），机制与 Puppeteer、Playwright 等工具相同。
所有通信都发生在你的电脑内部，连接地址固定为 127.0.0.1（本机回环地址）。
扩展不会向任何外部服务器发送请求。
二、扩展会访问什么
当你主动将某个标签页接入自动化会话后，扩展可以通过 Chrome DevTools Protocol 读取该页面内容并执行操作。
- 扩展只作用于你明确接入的标签页，不会自动接管任何页面。
- 页面内容仅传递给你本机运行的 Clawser 客户端，不经过任何第三方。
- 这些内容之后如何使用、是否保存，完全由你自己编写和运行的脚本决定，本扩展不参与。
三、本地存储
扩展仅在浏览器本地保存连接配置（本机 relay 端口号等），不保存任何浏览数据。 卸载扩展即全部清除。
四、权限说明
- debugger —— 通过 CDP 控制你接入的标签页。
- 全站访问 —— Clawser 是通用自动化工具，目标站点由你在运行时决定、 无法预先枚举，因此不能给出固定的网站列表。扩展不在任何站点执行后台活动。
- 标签页 / 当前标签页 —— 列出标签页供你选择接入，并把标签页状态 回报给你的本地脚本。
- 存储 —— 保存本机 relay 端口和连接配置。
- 闹钟 —— 在 service worker 被浏览器挂起后定时重连本机 relay。
- 网页导航 —— 感知已接入标签页的跳转，保持自动化会话同步。
五、政策变更
本政策如有变更，修订后的版本将发布在本页面，并更新页首日期。
