# HD auto-grants every WebView2 permission

Hydrogen Desktop's webview (Windows / WebView2) registers a
`PermissionRequested` handler that returns **ALLOW for every permission kind** —
microphone, camera, clipboard-read, geolocation, notifications, sensors, etc. So
**inside HD the user never sees a "this site wants to use your microphone /
camera / clipboard / location" dialog.** Webview apps that call `getUserMedia`,
read the clipboard, or ask for geolocation simply *work*, with no prompt.

Evidence: `hd-app/src/lib.rs` (~lines 326-349):

```rust
// PermissionRequested: auto-grant EVERY permission kind (clipboard
// read, mic, camera, geolocation, notifications, sensors, …) so the
// user never sees a WebView2 "site wants to" dialog.
…
args.SetState(COREWEBVIEW2_PERMISSION_STATE_ALLOW)?;
hd_log::hd_log!("[perm] auto-granted permission kind {:?}", kind);
```

Every request is unconditionally set to `COREWEBVIEW2_PERMISSION_STATE_ALLOW`. In
the HD log you'll see lines like `[perm] auto-granted permission kind …` and, at
startup, `[perm] Registered PermissionRequested auto-grant handler`.

## Why HD does this

HD is the user's **trusted desktop app** — they've already chosen to run it.
Intermediate per-site Web permission prompts (especially the clipboard-paste
dialog) are pure friction with no added safety here, since there's no untrusted
third-party browsing context: the surfaces are HD's own panels and the user's own
webview apps. So HD grants them all up front.

## What this means for you when building webview apps

- **Don't instruct the user to "click Allow."** There is no prompt — telling them
  to look for one is wrong and confusing. `getUserMedia({ audio: true })`,
  clipboard reads, geolocation, notifications all resolve without a dialog.
- If a webview app *isn't* getting mic/camera data, the cause is **not** a denied
  permission prompt (HD never denies). Look elsewhere: no device present, the
  page served over a non-secure context, a code bug, or the OS-level Windows
  privacy toggle for the camera/mic being off for the app entirely.
- This is WebView2/Windows-specific behavior baked into HD's webview host — it's
  not something the web page or the user configures.

## NOT the same as in-app screen-share / mic consent

This auto-grant is **only** the low-level WebView2 browser-permission layer.
It is separate from the **screen-share / microphone consent the AI itself
requests** when it wants to capture the user's screen or mic for a session — that
flow **is** explicitly user-approved (the user sees and accepts an in-app consent
UI). Don't conflate them: WebView2 site permissions are silently allowed; the AI's
capture/share request is a real, user-facing approval. See `hd-capture-share`.
