Focus Cloak

"Hide your current browser screen in 0.2 seconds and secure your personal privacy!" Focus Cloak is a high-quality privacy browser extension that instantly camouflages your active web browsing tabs into professional business mockups (Excel, Google Sheets, Jira, Notion) at the touch of a single hotkey. It doesn't just show a blank screen or a static image. It renders interactive, pixel-perfect mock UIs where you can actually click, select cells, edit data, and switch tabs, simulating an authentic work environment. #### ✨ Key Features 1. **High-Fidelity Interactive Decoy Screens** - **MS Excel Online Mode:** A green spreadsheet UI complete with formulas, sheet tabs, and data rows. You can actually double-click and edit numeric values, and the sheet's profit calculations and totals will automatically recalculate in real-time! - **Google Sheets Mode:** Google Sheets design loaded with mock sprint deliverables. Supports tab switching. - **Jira Kanban Board Mode:** Classic Jira developer backlog. Clicking on issue cards triggers a realistic side drawer that slides open to show issue details. - **Notion Mode:** A clean Notion workspace document with toggle checklists and timeline tables. 2. **Full Tab Camouflage (Title & Favicon Swap)** - The tab title is renamed to a corporate filename like `2026_Q2_Financial_Report.xlsx`, and the favicon is replaced with the Microsoft Excel/Notion icon. - It runs a lock engine that blocks websites (like YouTube or Gmail) from flashing notification updates on the tab title. 3. **Smart Media Control & Background Listening** - **Stealth Mode (Mute ON):** When activated, it pauses video/audio playback and mutes the tab. When deactivated, the video automatically resumes from where you left off. - **Background Mode (Mute OFF):** Perfect for background listening! The visuals are hidden behind the Excel sheet, but the music/podcast continues playing without pause. 4. **Sleek Settings Panel & Fast Hotkeys** - A beautiful glassmorphic dark-mode options popup to select your default decoy, toggles, and edit custom tab filenames. - Click the gear (⚙️) icon inside the popup to quickly customize the global activation hotkey. #### ⚙️ How to Use 1. Install and pin "Focus Cloak" to your Chrome toolbar. 2. Open the popup to select your default decoy screen (default: Excel) and customize tab titles. 3. Press **`Ctrl+Shift+Y`** (default) on any webpage to instantly cloak. 4. Press **`Ctrl+Shift+Y`** again to restore the original page. #### 🔒 100% Client-Side Privacy No analytics, tracking, or network collection. Focus Cloak runs entirely locally inside your browser.
