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.

Who it's for

People who show real screens to other people: agencies demoing a client's dashboard, support engineers screen-sharing a customer account, freelancers recording a walkthrough, teams streaming an internal tool. Anyone whose browser holds names, emails, invoices, tokens or customer IDs — and who would rather blur them once than edit them out of every recording afterwards.

Three rules the product is built on

Don't take our word for it — check

“Local only” is a claim, and claims about privacy should be testable. Three checks anyone can run in a minute:

1. 01

   Watch the network

   Open DevTools → Network on any page, then blur, redact and auto-detect. Nothing of what you blurred goes anywhere: no page content, no screenshots. The extension makes two kinds of request — a licence check for Pro, and anonymous usage counts you can switch off in settings. Neither carries what is on your screen.

2. 02

   Pull the plug

   Turn Wi-Fi off and keep working. Blur, redact, transparent, the blur list, saved profiles — everything runs exactly the same, because none of it depends on a server.

3. 03

   Read the permissions

   The store listing shows what the extension asks for: storage (your settings and profiles), context menus (right-click → blur), tabs (to know which tab to apply a profile to), and access to the pages you visit — that last one is what lets it draw a blur over them, and it is the same permission the privacy policy describes. It reads nothing and sends nothing. No account is required for the free version, and there is nothing to sign in to.
