DataBlur — DataBlur

Share your screen without sharing your secrets. DataBlur keeps sensitive information off your screen during live calls and recordings with deterministic, on‑device protection. No cloud, no accounts, zero external API calls. Blur elements, areas, selected text, and Mozilla tab titles in under 50 ms with smooth 60 FPS.

What DataBlur does:
- Prevents accidental exposure during screen shares and screen recording
- Masks emails, IDs, phone numbers, cards, passwords, and other PII in real time
- Works directly in Mozilla, locally on your device

Why it’s different:
- On‑device privacy by design. Your data never leaves the browser
- Deterministic PII detection with precise manual control
- Per‑domain rules that persist across sessions and tabs
- Built for live speed: sub‑50 ms actions and 60 FPS responsiveness

Key features:
- One‑click blur for elements, areas, and selected text
- Auto‑detect common PII (emails, phone numbers, cards, passwords)
- Title/tab masking to hide page titles during share and recording
- One‑click Remove All to reset instantly
- Keyboard shortcuts for every core action

Keyboard shortcuts:
- Alt+Shift+T — Toggle toolbar
- Alt+Shift+B — Blur selected text
- Alt+Shift+R — Remove all blurs
- Alt+Shift+A — Toggle auto‑detect
