About
Built so it can't leak.
DataBlur is a browser extension that blurs sensitive data on screen — before it reaches a screen share, a recording or a screenshot. It exists because redacting leaks after the fact is a losing game: one missed frame and the data is out. The safe habit is hiding it before it's ever captured.
That idea shapes every technical decision in the product, down to what happens when something breaks.
Three rules the product is built on
Local only
Every blur is computed on your device. No cloud, no AI, no account for the free version — DataBlur can't leak what it never receives.
Fail safe
When detection fails, DataBlur blurs more, not less. The default state is protected, never exposed — your career doesn't tolerate an 'oops' frame.
Free stays free
Every way of hiding data — blur, redact, transparent, manual and auto-detect — is free forever. Pro only removes the badge on auto-applied blurs and adds saved profiles.
