BlurShield
BlurShield 是一款面向 macOS 的菜单栏隐私工具，适合经常开会、录屏、远程演示的人使用。你可以提前把敏感应用加入保护列表，BlurShield 会在这些窗口出现时自动加上遮罩；如果临时情况更紧急，也可以一键拉起整屏黑幕，先把桌面保护住。
主要功能
- 菜单栏常驻：默认以轻量工具形态驻留在菜单栏，随时可用。
- 敏感应用预备保护：可以从正在运行的应用、已安装应用或 .app 文件中加入保护列表。
- 窗口级遮罩：当目标应用窗口出现时，自动在对应窗口上方加遮罩，而不是粗暴盖住整个工作流。
- 整屏黑幕：支持一键覆盖所有显示器，适合共享前的紧急场景。
- 快捷键触发：支持全局快捷键快速开启/关闭整屏保护。
- 本地优先：核心识别与遮罩逻辑在设备本地完成。
当前版本说明
- 免费版可先保护 1 个应用。
- BlurShield Pro 为一次性买断，当前代码中解锁项包括：无限应用保护、开机启动、自定义快捷键。
- 应用需要 macOS 的“屏幕录制”权限，才能正确识别窗口位置并让遮罩跟随窗口变化。
适用场景

- 销售演示、客户提案、远程培训
- 录屏、直播、产品 demo
- 同时开着 IM、邮件、后台系统、报价表时的桌面保护

BlurShield
BlurShield is a menu-bar privacy utility for macOS, built for people who regularly present, record, or share their screen. You can prepare a list of sensitive apps in advance, and BlurShield will place a shield over those windows when they appear. For urgent moments, you can also trigger a full-screen curtain instantly.
Key Features
- Menu-bar first: stays lightweight and ready from the macOS menu bar.
- Prepared app protection: add apps from the running list, installed apps, or a chosen .app file.
- Window-level shielding: protects specific app windows instead of blocking your whole workflow.
- Full-screen curtain: covers all displays for emergency privacy moments.
- Global shortcut: quickly toggle full-screen protection from anywhere.
- Local-first workflow: core window detection and shielding run on-device.
Current Version Notes
- The free plan currently protects 1 app.
- BlurShield Pro is positioned as a one-time unlock. In the current codebase, Pro features include unlimited app protection, launch at login, and custom shortcuts.
- The app needs macOS Screen Recording permission so it can inspect window geometry and keep shields aligned correctly.
Use Cases
- Privacy prep before sharing your screen in Zoom, Tencent Meeting, Feishu Meeting, and similar tools
- Sales demos, client presentations, and remote training
- Recording tutorials, live demos, and internal walkthroughs
- Protecting IMs, email, dashboards, or pricing sheets while working on a real desktop
