Key PII Protection Features
1. Automated Smart PII Shielding (Pro)
Scans your web dashboard on load to automatically mask email addresses, phone numbers, credit card strings, SSNs, and Stripe revenue balances before you present.
2. Precision Point, Click & Box Redaction
Click any DOM element to apply Gaussian blur, mosaic pixelation, or solid blackout redaction. Drag custom selection boxes over charts or table columns.
3. Preset Swapping for Recurring Demos
Save configuration presets (e.g. "Client Demo", "YouTube Recording") to apply pre-configured blur rules with a single click.
Where PII Hides on a Typical Dashboard
Manual blurring catches what you notice. Auto-detection catches what you don't. In practice, sensitive data hides in more places than most presenters expect:
- The obvious spots: customer names and emails in table rows, phone numbers in contact panels, card fields in payment screens.
- The sneaky ones: user IDs in URLs and breadcrumbs, account balances in page headers, invoice totals in sticky footers, and email addresses inside comment threads or activity logs.
- The loaded-later ones: notifications, toasts, and lazy-loaded table pages that appear mid-demo — which is exactly when auto-detection earns its keep.
Who Uses PII Redaction Day to Day
- Support leads walking through customer accounts on shared calls.
- QA and product teams recording bug reproductions that contain real user data.
- Finance and ops presenting revenue and payment dashboards to partners.
- Agencies demoing one client's workspace without exposing another's.
- Educators and creators publishing tutorials against live, realistic data instead of sanitized demo accounts.

Yes, BlurMask offers a Free Starter tier with up to 7 manual blurs per page forever. Lifetime Pro ($20 one-time) unlocks unlimited blurs and Smart PII detection.
