净域是一款在用户浏览器本机执行的广告过滤扩展。本政策说明净域处理哪些数据、为什么需要这些数据，以及数据会保存在哪里。
为了判断应当拦截或隐藏哪些内容，净域会在浏览器本机处理当前网页的地址、请求地址、页面结构和与过滤规则匹配所必需的信息。这些处理是广告过滤、网站放行、元素隐藏和规则订阅功能的必要组成部分。
净域还会处理用户主动设置的内容，包括：
chrome.storage.sync 保存。用户开启 Chrome 同步时，这些内容由 Google Chrome Sync 按用户的 Chrome 账号设置进行跨设备同步。净域没有开发者控制的账号系统、遥测端点、广告服务器或分析服务器，不会把浏览记录、网页内容或过滤日志发送给净域开发者。
净域会从扩展内列明的 EasyList、EasyList China、Japanese Filters、EasyPrivacy 和 Fanboy 官方分发地址更新规则。用户也可以主动添加其他 HTTPS 规则订阅。
当浏览器请求规则订阅时，相应的规则托管方会像普通网站服务器一样收到连接所必需的信息，例如 IP 地址、请求时间和基础网络请求信息。第三方订阅服务适用其各自的隐私政策；净域开发者不控制这些服务。
净域不会：
除用户选择的 Chrome Sync 和用户主动添加的规则订阅服务外，净域不会向第三方传输用户数据。
declarativeNetRequest：在浏览器中应用网络过滤规则。scripting 与网站访问权限：执行元素隐藏和用户启用的内容过滤规则。webNavigation、webRequest 与 tabs：识别页面和框架状态、应用文档级放行规则并处理弹窗过滤。storage 与 unlimitedStorage：保存过滤订阅、规则引擎数据和用户设置。净域不申请 declarativeNetRequestFeedback，不会读取浏览器的规则命中调试记录。
用户可以在净域设置中删除放行网站、自定义规则和订阅，也可以通过浏览器清除扩展数据或卸载净域。Chrome Sync 中数据的保留和删除同时受用户 Google 账号及 Chrome 同步设置控制。
如果净域的数据处理方式发生实质变化，本政策会更新生效日期，并在扩展或商店页面中作出明显说明。
隐私问题和数据删除问题，可通过净域 Chrome Web Store 商品页列出的支持联系方式，或项目的 GitHub Issues 联系发布者。涉及不宜公开的安全信息时，请优先使用 Chrome Web Store 商品页列出的支持联系方式。
用户主动反馈：联系 1793master@gmail.com。发送后我们会收到邮件地址及你选择提供的内容，仅用于回复、排查和产品改进，不用于营销；可通过同一邮箱要求删除。反馈页不自动采集浏览记录、配置或文件。

Jingyu is an ad-filtering extension that runs locally in your browser. It processes the current page URL, request URLs, page structure and information necessary to match filtering rules. This supports ad blocking, site exceptions, element hiding and rule subscriptions.
It also processes settings you choose: protection switches, filtering mode, allowed sites, custom filters, HTTPS subscription addresses and imported/exported configuration files.
Subscription bodies, engine state and operational data are stored locally. Small settings, allowed sites, custom filters and subscription addresses use chrome.storage.sync. If you enable Chrome Sync, Google synchronizes these according to your account settings. Exported JSON files are saved to the location you choose.
Jingyu has no developer-controlled user-account system, telemetry endpoint, advertising server or analytics server. It does not send your browsing history, page content or filtering logs to the developer.
Jingyu updates rules from the official distribution addresses listed in the extension for EasyList, EasyList China, Japanese Filters, EasyPrivacy and Fanboy lists. You can add other HTTPS rule subscriptions.
A rule host receives ordinary information needed for a network connection, such as your IP address, request time and basic request information. The host's privacy policy applies. Google handles Chrome Sync. The developer does not control those services.
Jingyu does not sell user data, use browsing activity for personalized advertising, share browsing data with data brokers or analytics platforms, or let the developer inspect your pages or personal filtering rules. The ordinary third-party connections described above are used only to provide the selected functionality.
Jingyu does not request declarativeNetRequestFeedback or read the browser's rule-match debugging records.
You can remove allowed sites, custom filters and subscriptions in Settings, clear extension data or uninstall Jingyu. Retention and deletion of synced data also depend on your Google account and Chrome Sync settings.
Email 1793master@gmail.com for support, feature requests, privacy questions or deletion requests. If you choose to send feedback, we receive your email address and the content you provide. It is used only to reply, diagnose problems and improve the product, not for marketing. You can request deletion by contacting the same address.
The feedback page does not automatically collect browsing history, configuration or files and does not send the email for you. Screenshots must be added by you; remove private information first. The public page host processes connection information needed to serve the page.
Material changes to data handling will be reflected in the date and described in the extension or store listing.
