# MetaScope – Privacy Policy

**Last updated: February 2026**

## Overview

MetaScope ("the Extension") is built with privacy as a first principle.
This document explains precisely what data the Extension accesses and how it is handled.

## What MetaScope Does NOT Do

MetaScope does **not**:
- Transmit any data to external servers or third parties
- Collect personal information of any kind
- Access or store your browsing history
- Read page content, passwords, form data, or cookies
- Run in the background or monitor your browsing passively
- Require an account, login, or registration
- Use analytics SDKs, advertising, or remote logging of any kind

## What Happens When You Click "Inspect"

When you click Inspect, the Extension injects a small function into
the currently active tab. That function reads only the following
from the page's DOM:

- `<meta>` element attributes: `name`, `property`, `content`, `charset`, `http-equiv`
- `<title>` element text
- `<link rel="canonical">` and `<link rel="alternate" hreflang>` attributes
- `<script type="application/ld+json">` content (parsed for schema @type only)
- `document.documentElement.lang`
- `document.title`
- `<h1>` element count and first H1 innerText

**No other page content is read.** The function does not access
passwords, form inputs, cookies, localStorage, user content,
or the body text of the page.

All extracted data is processed entirely within your browser.
No data is ever stored persistently — MetaScope holds results only
in memory while the popup is open, and discards them when it closes.

## Clipboard Access

When you click a copy button, the Extension writes meta tag text to
your clipboard using the `clipboardWrite` permission. The Extension
never reads your clipboard.

## Social Preview Images

The social card preview attempts to display the og:image URL found
on the page by rendering it in an `<img>` tag within the extension popup.
This image is fetched by your browser directly from the source URL —
MetaScope does not proxy or store it.

## Permissions Summary

| Permission       | Purpose |
|------------------|---------|
| `activeTab`      | Access the currently active tab when you click "Inspect" |
| `scripting`      | Inject meta extraction function into the active tab on demand |
| `clipboardWrite` | Write meta tag values to clipboard on user-initiated copy actions |
