## 外掛說明

Borderless Currency Calculator adds a configurable currency converter to WordPress
sites with the `[bccalc_currency_converter]` shortcode.

 * Live exchange rates from the free Fawaz Ahmed Currency API. No API key is required.
 * Exchange-rate responses are cached with the WordPress Transients API to reduce
   requests. The currency list is bundled locally so the settings page does not 
   need a separate external request.
 * Choose which currencies are available and set the default From and To currencies.
 * Includes flag indicators, responsive layout, currency swapping, and configurable
   appearance options.
 * Conversion amounts display with two decimal places and thousands separators, 
   while exchange rates display with four decimal places.
 * The plugin does not require an account or collect visitor information.

The exchange-rate service is provided by the Fawaz Ahmed Exchange API project:
 
https://github.com/fawazahmed0/exchange-api

### External services

This plugin connects to the Fawaz Ahmed Currency API to retrieve live currency exchange
rate data. This connection is necessary to show accurate conversion results in the
currency converter widget.

**What is sent:**
 When a conversion is requested, the plugin sends a server-side
HTTP GET request from your web server to the Fawaz Ahmed Currency API. The request
URL contains only the lowercase base currency code (for example, `usd`). No visitor
personal data, names, email addresses, IP addresses, or any other user-identifying
information is transmitted by the plugin.

**When data is sent:**
 A request is made when a visitor clicks “Convert” and the
plugin does not have a valid cached exchange rate for the selected base currency.
Exchange-rate data is cached server-side using WordPress transients for up to one
hour. No request is made during plugin installation, activation, or while browsing
the admin settings page.

**Request method:**
 Requests are made server-side via PHP (using WordPress’s wp_remote_get),
not from the visitor’s browser. The visitor’s browser does not contact the currency
API directly.

**Primary endpoint:**
 https://latest.currency-api.pages.dev/v1/currencies/{currency}.
min.json

**Fallback endpoint:**
 https://cdn.jsdelivr.net/npm/@fawazahmed0/currency-api@latest/
v1/currencies/{currency}.min.json

**Service:**
 Fawaz Ahmed Currency API (also known as the Exchange API) Project 
repository: https://github.com/fawazahmed0/exchange-api

**Terms of Service:**
 This API is a free, open-source project distributed under
a public-domain-equivalent license. The project does not publish a dedicated Terms
of Service document. Please review the project README and license at: https://github.
com/fawazahmed0/exchange-api

**Privacy Policy:**
 This API is a free, open-source project and does not publish
a dedicated Privacy Policy. The plugin does not send any personally identifiable
information to the API. Please review the project repository for details: https://

## 常見問題集

### Does this require an API key?

No. The Fawaz Ahmed Currency API does not require an API key for the exchange-rate
data used by this plugin.

### How are exchange rates fetched?

When a visitor clicks “Convert”, the plugin sends a server-side request (via WordPress’s
wp_remote_get) from your web server to the Fawaz Ahmed Exchange API. Only the base
currency code (e.g. “usd”) is included in the URL. No visitor personal data, IP 
addresses, or identifying information are sent by the plugin. The exchange-rate 
response is then cached using WordPress transients for up to one hour to reduce 
repeat requests.

### What happens if the currency API is unavailable?

The plugin tries the fallback endpoint. If both endpoints fail, the converter displays
an error instead of breaking the page. Previously cached rates remain available 
until their cache expires.

### How are numbers formatted?

Converted amounts use two decimal places and comma thousands separators, for example`
1,000.00`. The exchange-rate line uses four decimal places, for example `1 GBP =
1.3383 USD`.
