Compatible with your browser • Free install in 2 clicks • No signup required
When OBS Studio captures a Chrome window or display, any accidental reveal of an API token, customer email, or billing balance is broadcast live. Use Screen Privacy Blur to mask sensitive DOM elements beforehand.
Enable Smart Auto-Blur Pro masks for API keys, bearer tokens, emails, and cards, or lock manual frosted-glass overlays onto specific dashboard panels so they stay hidden as you scroll.
Use the Chrome extension for web consoles (AWS, Stripe, GitHub, Vercel) and pair it with the macOS desktop app to place click-through blur regions over native terminals or code editors.
When setting up Hide API keys and PII in OBS Studio & live streams (Hide Secrets in OBS Studio Streams | Screen Privacy Blur), Screen Privacy Blur runs 100% locally in your Chromium browser so private records, credentials, and financial balances remain hidden or replaced with realistic demo data before any frame is shared.
