## 外掛說明

Roughly a third of the world’s internet users live behind some form of national

censorship. Unbounded lets the people who visit your site help, without installing
anything: the widget adds a switch to your page, and a visitor who turns it on lends
a small amount of their bandwidth to relay traffic for someone whose government 
blocks the open internet.

Nothing happens until a visitor chooses it. The switch is off when the page
 loads,
and the proxy engine is not even downloaded until it is turned on. Visitors can 
turn it off at any time, and closing the tab stops it.

This plugin is the WordPress front end for that widget. It adds a settings
 screen
for the widget’s appearance and placement, and a checkbox in the page editor to 
turn it on for a given page.

#### What you can configure

 * **Layout** — banner, panel, floating, or simple
 * **Theme** — light, dark, or follow the visitor’s system preference
 * **Location** — top or bottom of the page
 * **Where it appears** — per page via the editor sidebar, on all posts, or on the
   homepage

#### Open source

Unbounded is developed in the open at
 [github.com/getlantern/unbounded](https://github.com/getlantern/unbounded).
The plugin source lives in `ui/wp-plugin`, and the widget it loads is in `ui/`.

### External services

This plugin is a client for the Unbounded network, run by Lantern. The widget
 cannot
work locally: relaying traffic for someone in another country requires peers, signaling,
and exit infrastructure, all of which live in the service.

When the widget renders on a page — before the visitor has done anything —
 their
browser contacts:

 * **embed.lantern.io** — serves the widget bundle and its images, and hosts a
    
   small invisible frame the widget uses to remember volunteering statistics.
 * **fonts.googleapis.com / fonts.gstatic.com** — the widget’s typeface,
    Urbanist,
   from Google Fonts.
 * **plausible.io** — usage analytics, loaded inside the embed.lantern.io frame.
   
   On load the widget sends it two events: that it rendered, tagged with the embed
   type (web page or browser extension), and the state of the switch, which is off.
   The switch event is sent again whenever a visitor changes it. The load event 
   carries the hostname of the page the widget is embedded on. While the switch 
   is on, one further event is sent each time the widget starts helping a new person,
   tagged with the same hostname. Every site that embeds the widget is listed automatically
   on unbounded.lantern.io/leaderboard and ranked by these counts. A site that should
   not appear there can ask to be removed at github.com/getlantern/unbounded/issues.
   Plausible’s own script adds its usual page metadata, including the frame’s referrer—
   the site the widget is embedded on, usually just the origin, as trimmed by that
   site’s referrer policy. Plausible is cookieless and keeps no persistent identifier
   for the visitor; Lantern uses the counts to report how many sites run the widget
   and how many visitors volunteer.

Nothing else is contacted until a visitor turns the switch on. After that:

 * **embed.lantern.io** — the WebAssembly proxy engine, around 12 MB, which is
    
   why it is fetched on demand from the service rather than bundled into this plugin.
 * **geo.getiantem.org** — a country lookup, used to draw the map and to warn
    visitors
   who appear to be in a censored region that volunteering may not be appropriate
   for them.
 * **freddie.iantem.io** — peer discovery and connection signaling.
 * **unbounded.iantem.io** — the exit servers that relayed traffic egresses
    through.
   If the widget’s page freezes or crashes, a diagnostic report is also sent here:
   timing measurements, the page’s address, the browser’s user-agent string, and
   the widget build. It carries no identifier for the visitor.
 * **netstated-d7bbec1ed55b.herokuapp.com** — anonymous network-state updates
    that
   power the live map of active connections.

#### What is kept in the visitor’s browser

The widget stores a few values in browser storage: the interface language, a
 crash-
recovery marker, and — inside the embed.lantern.io frame, so it follows the visitor
across sites that run the widget — running totals of people helped. None of it identifies
the visitor.

Unbounded does not track visitors, set advertising identifiers, or collect
 personal
data. Relayed traffic is end-to-end encrypted between the person being helped and
their destination; a volunteering browser cannot read it.

By installing and enabling this plugin you are choosing to load the widget from

these services on the pages you enable it for. Please tell your visitors, and add
it to your own privacy policy if you have one.

## 安裝方式

 1. Install and activate the plugin.
 2. Open **Unbounded** in the admin sidebar and pick a layout, theme, and location.
 3. Decide where the widget appears. Either tick **Display on Homepage** or
     **Display
    on Posts** on that settings screen, or enable it for individual pages: edit a page
    and tick **Enable Unbounded on this page** in the editor sidebar.
 4. View the page. The widget renders with its switch off, waiting for a visitor
     to
    opt in.

## 常見問題集

### Does this slow down my site?

The widget bundle is deferred, so it does not block rendering. The proxy engine

is only downloaded for visitors who turn the switch on.

### Does it use my visitors’ bandwidth without asking?

No. The switch is off on page load and the proxy engine is not downloaded until

a visitor turns it on. Turning it off, navigating away, or closing the tab stops
it.

### Can my visitors get in trouble for volunteering?

Volunteers relay encrypted traffic; they are not the exit point, so traffic does

not appear to originate from their connection. The widget also detects when a visitor
appears to be in a censored region and warns them before they opt in. See the privacy
policy for details.

### Can I host the widget bundle myself?

Yes, with the `browsers_unbounded_script_url` filter. Be aware that a
 self-hosted
copy is pinned to whatever build you copied and will eventually fall out of step
with the network, so the hosted URL is the default.

### Why is the HTML element called “browsers-unbounded”?

The product used to be called Browsers Unbounded. The element name is the
 widget’s
public API and renaming it would break every existing embed, so it stayed.
