BlurGuard

Blur sensitive data on any webpage before sharing your screen. 100% local — no cloud, no analytics.

Hide sensitive data on any webpage before you share your screen. Working remotely means screenshots, recordings, and screen shares. BlurGuard makes sure passwords, emails, phone numbers, credit card numbers, and API keys never appear on screen when you don't want them to — across Zoom, Google Meet, Microsoft Teams, OBS, Loom, or any other recorder. Everything happens locally in your browser. No servers, no cloud, no accounts, no analytics, no tracking. ✦ FOUR WAYS TO BLUR ✦ • Click-to-blur element — right-click any form, token, or row and choose "Blur element", or click the toolbar button. • Draw a blur area — drag to cover a region; ideal for maps, charts, and side panels. • Text blur — select text and it auto-blurs. • Image swap — replace any <img> with a URL you choose. ✦ AUTO-DETECT PERSONAL DATA ✦ One click scans the page and masks emails, phone numbers, credit cards (Luhn-validated), SSNs, API keys, JWT tokens, passwords, private keys, and database connection strings. Per-category toggles let you control exactly what gets hidden. New content added to the page is re-scanned automatically. ✦ FIVE RENDERING STYLES ✦ Cycle between Blur (adjustable intensity), Block (solid fill), Redact (replace text), Transparent, and Color. ✦ STAYS OUT OF YOUR WAY ✦ • Persistent per-site rules — blurs are remembered for each site and reappear automatically on every visit. • Saved profiles — switch between a "demo" and a "full" profile per site. • Keyword / regex blocklist — always-blur specific terms or patterns. • Peek — hold a button to temporarily reveal hidden text, release to re-hide. • Present mode — hide all editing handles for a clean, shareable view. • Tab identity masker — replace the tab title and favicon with a neutral placeholder. ✦ KEYBOARD SHORTCUTS ✦ • Alt+Shift+B — toggle blur picker (element / area / text) • Alt+Shift+A — toggle auto-detect personal data • Alt+Shift+R — remove all blurs on the page • Alt+Shift+T — show / hide the floating toolbar ✦ WHO IT'S FOR ✦ Developers live-coding or demoing dashboards. Support and ops agents handling client data. Streamers, presenters, and teachers. Anyone who shares a screen, takes screenshots, or records their browser. ✦ PRIVACY BY DESIGN ✦ • 100% local — your data never leaves your browser. • Minimal permissions: only "storage" (to remember your blur rules) and "contextMenus" (for the right-click menu). • No host permissions, no access to your tabs or browsing history. • Free, with no account required and no paywall. Blur first. Share with confidence.
