Privacy Policy

Summary

We don't collect, store on our servers, sell or share any of your data. We don't run any servers. Everything the extension does happens inside your own browser.

What the extension accesses

• Follower list (public profile info): display names, @usernames and profile-picture URLs of the account you choose and its followers. This is read from x.com when you click the button, only to draw the image.
• Profile pictures: loaded from pbs.twimg.com and drawn onto an image in your browser.
• Your existing x.com session: the requests run inside your open x.com tab and use the session you already have, exactly as x.com's own website does. The extension never asks for, sees or stores your password. It does not use OAuth or API keys.

How it is used and stored

• Used only to generate the mosaic image you asked for.
• The follower list exists only in the memory of your x.com tab while the extension's panel is open, and is discarded when you close it. Only small preferences (interface language, font, custom text) are saved in chrome.storage.local on your computer.
• The image is saved to your computer only when you click "Download".

What we never do

• No data is sent to the developer or to any third party. There are no analytics, ads or tracking.
• No posting, following, liking, messaging or any other change to any account. All requests are read-only.
• No selling or transferring of data, and no use for purposes unrelated to making the image.

Permissions

activeTab and scripting run the extension's bundled helper in the x.com tab, only after you click the toolbar button. Host access to x.com / twitter.com lets a tiny script note the follower-list requests x.com itself makes (kept in the tab's memory only, nothing is sent anywhere) and re-open the panel if it had to reload the page once. storage keeps small preferences (language, font, custom text, reading speed, follower limit) locally. No other website is accessed.

隐私政策（中文）

我们不收集、不上传、不出售、不分享你的任何数据，也没有任何服务器。所有处理都在你自己的浏览器里完成。

• 会读取：你选择的账号及其粉丝的公开昵称、用户名、头像链接（在你点击按钮后从 x.com 读取），仅用于生成图片。
• 登录状态：请求在你已打开的 x.com 页面中进行，沿用你现有的登录，和 X 网页本身一样；插件不会索取、看到或保存你的密码，不使用 OAuth 或 API Key。
• 本地保存：粉丝列表只在 x.com 页面的插件面板打开期间存在于内存中，关闭即丢弃；本机 chrome.storage.local 只保存界面语言、字体、自定义文字等小设置。
• 绝不：上传数据、统计追踪、投放广告；绝不发帖、关注、点赞或私信；所有请求均为只读。
• 权限：activeTab、scripting（仅在你点击插件按钮后，在 x.com 页面运行插件自带脚本）；只访问 x.com / twitter.com：一个小脚本在本页内存里记下 x.com 自己加载的粉丝列表请求（不发送到任何地方），并在插件需要刷新页面时自动重新打开面板，storage（本地保存语言、字体、读取速度等小设置）。
