Mark any window as private. On your own monitor everything looks completely
normal — but on every screen-share, recording, and live stream, the marked
windows show up heavily frosted. Zoom, Teams, Meet, OBS: it works the same
everywhere, because you share BLUR's safe copy, not your raw screen.

## What it does

- **Mark windows private in one click** — tick the apps no one should see
  (Slack, your inbox, a CRM, Discord, donation alerts) from a list of open
  windows. Everything else stays exactly as it is.
- **You share a safe surface, not your screen** — BLUR captures your display,
  frosts the marked windows on its own GPU copy, and hands *that* to the meeting
  or streaming app. The raw sensitive window is never exposed.
- **Live-tracked, leak-proof** — frost panels follow protected windows as they
  move, resize, or get covered, with motion smoothing so nothing slips through
  during a transition.
- **A panic hotkey for surprises** — one global keypress instantly frosts
  everything, for the pop-up no rule can anticipate.

## Local by design

All capture and compositing stay in memory and on the GPU — no frame is ever
written to disk or sent over the network. No cloud, no telemetry, no account,
and even the license is verified offline on-device. For a tool that sees your
whole screen, that's the whole point.

## Built for two kinds of leak

The same engine serves compliance-sensitive professionals — support, finance,
healthcare, legal, sales — who screen-share real data all day, and streamers on
multi-monitor rigs guarding DMs, personal tabs, and viewer names from the live
broadcast and the permanent VOD.

## Availability

BLUR is a Windows 10 & 11 app, launching soon. The download isn't ready yet —
check back shortly.
