Privacy Screen Blur

Stop accidentally leaking your data during screen-shares, demo recordings, or in coffee shops. Privacy Screen Blur gives you three precision tools to hide sensitive content on any website — all running 100% locally on your machine. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS THIS FOR? • People sharing their screen during meetings who want to hide sensitive info. • Content creators recording tutorials on Gmail, Stripe, GitHub • Anyone working with sensitive documents in a café, plane, or open office • Anyone sharing a screen that has sensitive info not meant to be leaked ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THREE BLUR MODES 🔍 SURGICAL BLUR (the precision tool) Click any element on the page — an email address, an account balance, a customer name — and it gets blurred. The blur persists across page reloads and even SPA navigation, so you never have to re-mark the same thing twice. Selectors are remembered per-domain, so a blur on gmail.com doesn't follow you to github.com. 🔦 GLOBAL SHIELD + FLASHLIGHT REVEAL (the everything-blur) One toggle blurs the entire page. But here's the trick: a clear "spotlight" follows your cursor, so you can read whatever you're hovering over without exposing the rest of the page. Perfect for reading sensitive documents in public — anyone glancing over your shoulder only sees the line you're actively reading. 📦 AREA SHIELDS (for non-standard content) Some things are hard to target with a click — embedded videos, canvas charts, account dashboards built from dozens of divs. Just drag a rectangle over the area and the extension drops a backdrop-blur shield over it. Shields scroll with the page and survive reloads. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY-FIRST BY DESIGN • 100% local. The extension never makes a single network request. • No accounts, no email collection, no PII. • No analytics, no telemetry, no third-party SDKs. • All settings stored in chrome.storage.local on YOUR machine. • Domain keys use hostname only — never full URLs or query strings. If you inspect this extension's network tab, you will see nothing. Privacy tools should earn trust through transparency, and that's exactly how we built this. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEYBOARD SHORTCUTS • Alt + S — Open the editing sidebar on the current page ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERMISSIONS — WHY WE ASK FOR THEM • activeTab: To apply blur changes to your currently focused tab when you click the extension icon. • storage: To remember your blur preferences locally between sessions. • Read/change data on all websites: So you can choose which sites to blur — a fixed allow-list would defeat the purpose. The content script only runs on tabs you actively visit. We have intentionally avoided requesting the "tabs" and "scripting" permissions to keep the footprint as small as possible.
