vdoc ("we", "our", or "the extension") is a browser extension that enables users to copy math formulas from web pages and paste them into Microsoft Word or PowerPoint as native, editable equations. We are committed to protecting your privacy.
vdoc does not collect, store, transmit, or share personal data or browsing content.
Specifically, the extension:
Formula detection, conversion, and clipboard operations happen locally on your computer. To remain compatible when supported websites change their markup, the extension periodically downloads a small, public compatibility configuration from this project's GitHub Pages site. The configuration only selects and orders formula adapters already bundled with the extension; it contains no executable code.
The configuration request does not include the current page URL, page content, formulas, clipboard content, or personal identifiers. As with any web request, GitHub may receive standard network metadata such as your IP address and browser user agent.
The extension requests the following browser permissions:
vdoc uses GitHub Pages only to host the public compatibility configuration. It does not use analytics, advertising, telemetry, or other third-party APIs.
No personal data is retained by vdoc. Chrome locally stores your preferences and the last verified compatibility configuration; Chrome removes extension storage when you uninstall the extension.
vdoc does not knowingly collect any information from children under the age of 13 or any other age group, as it does not collect any information from anyone.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last Updated" date.

vdoc（以下称"我们"或"本扩展"）是一款浏览器扩展程序，允许用户复制网页上的数学公式，并以原生可编辑格式粘贴到 Microsoft Word 或 PowerPoint 中。我们致力于保护您的隐私。
vdoc 不收集、不存储、不传输、不共享个人数据或浏览内容。
具体而言，本扩展：
公式识别、转换和剪贴板操作均在您的计算机本地完成。为了在支持的网站更新网页结构后保持兼容，本扩展会定期从本项目的 GitHub Pages 下载一份很小的公开兼容配置。该配置只能选择和排列扩展已经内置的公式适配器，不包含可执行代码。
配置请求不会携带当前网页地址、网页内容、公式、剪贴板内容或个人标识。与普通网络请求一样，GitHub 可能收到 IP 地址、浏览器 User-Agent 等标准网络元数据。
本扩展请求以下浏览器权限：
vdoc 仅使用 GitHub Pages 托管公开兼容配置，不使用分析、广告、遥测或其他第三方 API。
vdoc 不保留个人数据。Chrome 会在本地保存您的偏好和最近一次校验成功的兼容配置；卸载扩展时，Chrome 会删除扩展存储。
vdoc 不会有意收集任何 13 岁以下儿童或任何年龄段用户的信息，因为本扩展不收集任何人的信息。
我们可能会不时更新本隐私政策。任何更改将在本页面上反映，并更新"最后更新"日期。
