Ask HN: How do you prevent sensitive data leaks in screen-recorded demos?

I nearly exposed user data in a product demo and started using a strict pre-record checklist.

My current workflow: 1) use demo-safe seed data 2) identify sensitive fields before recording 3) apply blur/mask before hitting record 4) refresh once to verify persistence 5) run a 30-second dry run

This reduced both editing time and stress.

Curious what workflows/tools people here use for screen recording privacy (especially for SaaS demos and tutorials).

Context/tool I built while solving this: https://blurmate.devstorex.top
