BlurMyScreen

Blur, mosaic, cover, or blackout any tab. Regional blur, auto-blur on idle, and PIN lock. Private and local — collects no data.

BlurMyScreen lets you hide your screen content with one click — ideal for video calls, screenshares, working in public, or any moment you need instant privacy. ── Features ── • Four ways to hide your screen - Blur: Smooth Gaussian blur applied via CSS filter — covers everything including HTML5 video and canvas elements. - Mosaic: Fine tile pixelation using a live screenshot of the page. - Cover: A solid colour of your choice, at an adjustable opacity. - Black: Instant full blackout, one click. • Regional blur Don't want to blur the whole tab? Drag a box over just the part you need hidden — a password field, a chat preview, anything. It stays locked onto that spot even as you scroll the page. • Auto-blur Automatically blurs your tab after your mouse sits idle for a set number of seconds — useful for stepping away without thinking about it. • Screen lock with PIN Instantly black out the screen and require a PIN to unlock. The PIN is hashed before it's stored — never saved in plain text, never leaves your device. • Adjustable intensity Slider from 1 to 20 — fine-tune the strength of Blur, Mosaic, and Cover. • Keyboard shortcut Toggle blur instantly with Ctrl+Shift+U (Cmd+Shift+U on Mac) without opening the popup. Want a different combo? The popup links straight to Chrome's shortcut settings. • Your preferences are saved Mode, intensity, colour, and lock settings are remembered across sessions via local browser storage. ── Privacy ── BlurMyScreen collects no data whatsoever. No analytics, no tracking, no remote servers. All processing happens locally inside your browser. Preferences and your optional PIN (hashed, never plain text) are stored only in chrome.storage.local on your own device and never leave it. Mosaic mode's screenshot is held in memory just long enough to render the effect, then discarded — never written to disk or sent anywhere. ── Permissions ── Only three minimal permissions are requested — no broad host access, no "<all_urls>". ---Updates (v1.2.0)--- - New Black mode for instant blackout, and Cover mode with a custom colour (replaces the old Pixel mode) - Regional blur: hide just one part of the screen — it tracks scroll so it never slips out of place - Auto-blur on idle, with a configurable delay - Optional PIN-protected screen lock (PIN is hashed, not stored in plain text) - Redesigned popup with clearer, more direct controls
