Share your screen
without sharing your secrets.

Blur your screen in one click, for live calls, screen sharing and recordings.

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.
