隐私政策（中文）
「图片下载器 / Image Downloader」（以下简称"本扩展"）尊重并保护用户隐私。本政策说明本扩展会接触哪些信息、如何使用，以及这些信息的去向。
一、我们收集哪些信息
本扩展不收集、不存储、不传输任何个人信息。具体来说：
- 不收集账号、姓名、邮箱、电话等身份信息（本扩展没有注册和登录功能）。
- 不收集、不上传你的浏览历史、访问的网址、页面内容。
- 不含任何统计、埋点、广告或分析 SDK。
- 不含任何远程代码，所有逻辑都写在扩展安装包内。
- 不使用 Cookie，也不在任何服务器上留记录（本扩展没有服务器）。
二、本扩展在本地处理哪些信息
为了让功能正常工作，本扩展会在你打开商品页时读取当前页面上的图片与视频地址，把这些文件下载到本机，并打包成一个 zip 交给你。
- 这些信息只在你当前打开的这个页面内被读取和使用，处理完即丢弃。
- 扩展不保存这些地址，也不保存下载记录。
三、保存在本机浏览器里的设置
本扩展只用浏览器的本地存储保存一项设置：你在弹窗里选择的界面语言（中文／English／跟随浏览器）。
- 这条设置保存在你自己的浏览器里，不上传、不同步、不共享。
- 除它之外，本扩展不写入任何其它数据（没有账号、没有统计、没有下载记录）。
四、关于权限
本扩展申请两个权限，用途如下：
- 网站访问权限（
*://*/*）
- 在商品页注入下载按钮：内容脚本只在 https 页面注入，并且只有在识别出页面属于我们支持的电商站点时才显示按钮，其它页面没有任何界面和动作。
- 取回原图与视频：商品图片和视频放在各站点的 CDN 或第三方图片域名上，这些地址不提供跨域响应头。扩展需要在后台以扩展身份请求这些文件，再把文件内容交回页面打包下载。
- 支持站点会持续增加：站群和它们的图片域名随版本更新变化，无法在安装时固定成一份白名单。
- 存储权限（
storage）：仅用于保存上面第三节里那一项界面语言设置。
本扩展不申请下载、标签页、webRequest、书签、历史记录等任何其它权限。
五、数据共享
本扩展不与任何第三方共享、出售或转让用户数据，因为本扩展根本不收集数据。
六、第三方服务
本扩展不集成任何第三方服务、服务器或统计接口。下载图片时浏览器会直接访问商品页图片所在的域名，这属于浏览器对目标站点的普通网络请求，不包含任何用户标识信息。
七、儿童隐私
本扩展不面向儿童，也不收集任何用户数据。
八、政策变更
若本政策有更新，我们会在此页面更新内容与生效日期。
九、联系方式
如有任何疑问（包括想删除你反馈时附带的任何信息），请通过邮件联系：service@wios.cloud
Privacy Policy (English)
「Image Downloader / 图片下载器」(the "extension") respects and protects your privacy. This policy explains what information the extension touches, how it is used and where it goes.
1. What we collect
The extension does not collect, store or transmit any personal information. Specifically:
- No account, name, e-mail or phone number is collected (there is no sign-up and no login).
- Your browsing history, the sites you visit and page content are neither collected nor uploaded.
- There is no analytics, tracking, advertising or profiling SDK.
- There is no remote code; every line of logic ships inside the extension package.
- No cookies are used, and there is no server that could log anything (the extension has no backend).
2. What the extension processes locally
To do its job, the extension reads the image and video URLs of the product page you currently have open, downloads those files to your computer and packs them into one zip file for you.
- That information is read and used only inside the page you have open, and is discarded once the download is done.
- The extension does not store those URLs and keeps no download history.
3. The one setting stored in your browser
The extension uses the browser's local storage for exactly one setting: the interface language you pick in the popup (Chinese / English / follow browser).
- That setting stays in your own browser and is never uploaded, synced or shared.
- Nothing else is written (no account, no statistics, no download history).
4. Permissions
- Host permission (
*://*/*)
- Injecting the download button on product pages: the content script only runs on https pages and only shows the button when the page is recognised as one of the supported marketplaces. On any other page nothing is displayed and nothing is done.
- Fetching full size images and videos: those files live on each marketplace's CDN or on third-party image domains that do not send CORS headers. The extension fetches them from its background service worker and hands the bytes back to the page for packing.
- Supported sites keep growing: the marketplaces and their image domains change with every release, so they cannot be reduced to a fixed installation-time list.
- Storage permission (
storage): used only to remember the interface language described in section 3.
The extension does not request downloads, tabs, webRequest, bookmarks, history or any other permission.
5. Data sharing
The extension does not share, sell or transfer user data to anyone, simply because it does not collect any.
6. Third-party services
The extension integrates no third-party service, server or analytics endpoint. When downloading, the browser talks directly to the domain that hosts the product images — an ordinary network request to that site, carrying no user identifier.
7. Children's privacy
The extension is not directed at children and collects no user data.
8. Changes to this policy
If this policy changes, the content and effective date on this page will be updated.
9. Contact
For any question (including deleting anything you may have sent us while reporting an issue), e-mail service@wios.cloud.
