This extension does not collect, store, or transmit any personal data.
What is stored
Your filter rules, toggles, and thresholds are saved with chrome.storage.sync. They stay in your own browser and sync through your Chrome account. The developer has no access to them.
Page text
To decide whether a post matches your rules, the extension reads text already rendered on the page: display name, @handle, post body, and card text. This happens in page memory, is discarded after matching, and is never written to storage or sent anywhere.
Account metrics
Only after you turn on "hide replies by following / follower count" does the extension read the API responses X returns to the page, taking the reply author's follower count, following count, and verified status. With the switch off it reads nothing. Direct-message endpoints are skipped entirely. Those numbers stay in the memory of the current tab, disappear when the tab closes, and are never stored or sent anywhere. The extension makes no network requests of its own.
What it does not do
No analytics. No remote code. No contact with any server. It does not read direct messages, passwords, cookies, or login credentials. It does not run on any site other than x.com and twitter.com.
Permissions
storage saves your rules. Host permissions for x.com and twitter.com let the extension read post text on those sites and hide matching posts.

简体中文
这个扩展不收集、不存储、不传输任何个人数据。
存在哪里的数据
你的过滤规则、开关状态和阈值设置通过 chrome.storage.sync 保存。它们存在你自己的浏览器里，随你的 Chrome 账号同步，扩展作者无法访问。
页面文本
为了判断一条帖子是否符合你的规则，扩展会读取页面上已经渲染出来的帖子文本：显示名、@用户名、正文、卡片文字。读取发生在页面内存中，匹配完即丢弃，不写入存储，不发送到任何地方。
账号指标
只有在你打开「按关注 / 粉丝数隐藏回复」之后，扩展才会读取 X 返回给页面的接口响应，从中取出回复作者的关注数、粉丝数和认证状态；这个开关关着时不做任何读取。私信相关的接口一律跳过。取到的数值只留在当前标签页的内存里，关闭标签页即消失，不写入存储，不发送到任何地方。扩展不发起任何自己的网络请求。
不做的事
没有分析统计代码。没有远程代码加载。不联系任何服务器。不读取私信、密码、Cookie 或登录凭据。不在 x.com 和 twitter.com 以外的站点运行。
权限
storage 用于保存你的规则。x.com 与 twitter.com 的主机权限用于读取这两个站点的帖子文本并隐藏匹配项。
