DARKCAT Privacy Policy
Effective date: 25 September 2026
This policy explains how the DARKCAT Chrome extension handles information.
Information processed on your device
DARKCAT reads the address and styling of webpages where it runs so it can select and apply a dark theme. It processes webpage content and browsing activity locally for this user-facing feature. It does not send your browsing history, page content, or visited-site addresses to a DARKCAT-operated server.
DARKCAT may request stylesheet resources from the website origins referenced by a page. Those requests go to the respective website origins and may expose ordinary connection information, such as your IP address and request headers, to those sites.
The extension stores preferences, site rules, and custom theme settings in Chrome extension storage. Settings synchronization is enabled by default. When Chrome Sync is available and enabled, Chrome may synchronize this information through the Google account associated with the browser. You can turn off settings synchronization in DARKCAT settings; settings will then remain local.
DARKCAT also records the installation version and date in extension storage to support its interface. It does not request or store email addresses or activation keys.
Configuration downloads
If you enable synchronized site-fix configuration, DARKCAT downloads theme configuration files from the Dark Reader project's public GitHub repository. These requests retrieve configuration files and do not include your current website address in the request URL. GitHub may receive ordinary connection information, such as your IP address, under GitHub's privacy practices.
Sharing, retention, and security
DARKCAT does not sell personal information, use analytics or advertising trackers, or share browsing data with advertisers. Settings remain in Chrome extension storage until you delete them, uninstall the extension, or Chrome removes its local or synchronized extension data. Chrome Sync and GitHub handle information under their own terms and privacy policies.
Chrome Web Store Limited Use
DARKCAT uses webpage addresses, styles, and related content only as needed to apply the dark theme and provide user-controlled appearance settings. It does not use this information for advertising, credit decisions, sale, or unrelated purposes. It does not transfer browsing data to DARKCAT-operated servers.
Changes and contact
This policy may be updated when DARKCAT's data handling changes. Privacy questions or data requests: iskfcu@gmail.com

DARKCAT 隐私政策
生效日期：2026 年 9 月 25 日
本政策说明 DARKCAT Chrome 扩展如何处理信息。
在设备上处理的信息
DARKCAT 会读取其运行网页的地址和样式，以选择并应用深色主题。为提供此项用户功能，扩展会在本机处理网页内容和浏览活动；不会把浏览历史、页面内容或访问的网站地址发送到 DARKCAT 运营的服务器。
DARKCAT 可能会向网页引用的相应网站来源请求样式表资源。这些请求发送给对应网站，可能向其暴露 IP 地址、请求标头等普通连接信息。
扩展会将偏好设置、网站规则和自定义主题保存在 Chrome 扩展存储中。默认情况下，设置同步已开启。Chrome 同步可用且已启用时，Chrome 可能通过浏览器关联的 Google 账号同步这些信息。你可以在 DARKCAT 设置中关闭设置同步；之后设置仅保存在本机。
扩展还会在扩展存储中记录安装版本和日期，用于界面功能。DARKCAT 不会请求或保存邮箱地址、激活码。
配置文件下载
如果你开启“同步网站修复配置”，DARKCAT 会从 Dark Reader 项目的公开 GitHub 仓库下载主题配置文件。请求仅用于获取配置文件，不会在请求网址中包含当前网站地址。GitHub 可能根据其隐私规则接收 IP 地址等普通连接信息。
信息共享、保留与安全
DARKCAT 不出售个人信息、不使用分析或广告跟踪器，也不向广告商共享浏览数据。设置会保留在 Chrome 扩展存储中，直到你删除设置、卸载扩展，或 Chrome 清除本机或同步的扩展数据。Chrome Sync 和 GitHub 按各自的条款与隐私政策处理相关信息。
Chrome Web Store Limited Use
DARKCAT 仅在应用深色主题和提供用户控制的外观设置所需范围内使用网页地址、样式及相关内容；不会将这些信息用于广告、信用评估、出售或无关目的，也不会将浏览数据传输到 DARKCAT 运营的服务器。
