# Hide From Screen Capture

Obsidian plugin that excludes all Obsidian windows (main window and any
popped-out panes) from screen-share/recording capture on Windows, using
`SetWindowDisplayAffinity(WDA_EXCLUDEFROMCAPTURE)` via Electron's
`BrowserWindow.setContentProtection()`.

## How it works

- A ribbon icon (left sidebar) toggles capture-hiding on/off.
  - Protected: `eye-off` icon, highlighted.
  - Unprotected: `eye` icon, normal.
- Hiding is **enabled by default** on first install.
- The toggle state persists across restarts.
- Obsidian's Settings dialog is an in-window modal (not a separate OS
  window), so it is automatically covered whenever the main window is
  protected. Popped-out tab windows are protected too, via Obsidian's
  `window-open` workspace event.
- Windows-only. On other platforms the ribbon button is inert (no-op, no
  errors).
- Disabling/removing the plugin turns protection back off on unload.

## Install (manual / dev)

```
npm install
npm run build
```

Then copy (or symlink) `manifest.json`, `main.js`, and `styles.css` into
`<vault>/.obsidian/plugins/hide-from-capture/`, and enable the plugin from
Obsidian's Community Plugins settings.

For iterative development, use `npm run dev` (esbuild watch mode) and
symlink the plugin folder into your vault so rebuilds are picked up
without recopying.

## Verifying it works

Press `Win+Shift+S` (Snipping Tool) and try to capture the Obsidian
window while protection is enabled — it should appear black or be
omitted from the capture. Toggle the ribbon button off and repeat to
confirm the window captures normally again.
