Frankfurter API (api.frankfurter.app)** Used for: Fetching live exchange rates for major world currencies (USD, EUR, GBP and others). Data sent: The base currency code (e.g. “USD”) and target codes (e.g. “EUR,GBP”). No personal data, no user data, no store data. When: Only on admin action (“Fetch Live Rates” button click). Provider: Frankfurter is a free, open-source exchange rate API with no user registration required. Source code and terms: https://github.com/hakanensari/frankfurter (MIT license, no separate Privacy Policy — no personal data is collected or stored by this service) API endpoint: https://api.frankfurter.app/latest **2. ExchangeRate-API Free Tier (open.er-api.com)** Used for: Fallback exchange rates for currencies not covered by Frankfurter. Data sent: The base currency code only (e.g. “USD”). No personal data, no user data, no store data. When: Only on admin action (“Fetch Live Rates” button click) and only if Frankfurter did not return a rate for a given currency. Terms of Service: https://www.exchangerate-api.com/ terms Privacy Policy: https://www.exchangerate-api.com/privacy API endpoint: https:// open.er-api.com/v6/latest/ Both services are free, require no API key or account, and receive no personal data whatsoever. ## Screenshots [⌊Currencies tab — USD, EUR and GBP ready to go on activation⌉⌊Currencies tab — USD, EUR and GBP ready to go on activation⌉[ Currencies tab — USD, EUR and GBP ready to go on activation [⌊Exchange Rates tab — one-click Fetch Live Rates⌉⌊Exchange Rates tab — one-click Fetch Live Rates⌉[ Exchange Rates tab — one-click Fetch Live Rates [⌊Floating currency switcher on the frontend⌉⌊Floating currency switcher on the frontend⌉[ Floating currency switcher on the frontend ## Installation 1.

[Browse the code](https://plugins.trac.wordpress.org/browser/kazzylen-smart-multi-currency-for-woocommerce/), check out the [SVN repository](https://plugins.svn.wordpress.org/kazzylen-smart-multi-currency-for-woocommerce/), or subscribe to the [development log](https://plugins.trac.wordpress.org/log/kazzylen-smart-multi-currency-for-woocommerce/) by [RSS](https://plugins.trac.wordpress.org/log/kazzylen-smart-multi-currency-for-woocommerce/?limit=100&mode=stop_on_copy&format=rss). ## Changelog #### 1.1.1 * Update: Version 1.1.1, Stable tag 1.1.1 #### 1.1.0 * Add: 3-currency limit — users can add, edit and delete any 3 currencies of their choice; attempting to add a 4th shows a clear message to delete one first * Add: Currency count display in the Currencies tab header (e.g. “Managing 3 of 3 currencies”) * Add: Add Currency button is hidden and replaced with a plain “3 / 3 currencies” badge when the limit is reached * Fix: Removed promotional upsell card from Settings tab * Update: Version 1.1.0, Stable tag 1.1.0 #### 1.0.5 * Fix: Restored full add/edit/delete/set_default currency functionality — WP.org flagged limiting to 3 currencies as trialware since the underlying DB/session/ converter logic already supports arbitrary currencies; free plugin is now fully functional with no restrictions * Fix: Shortcode renamed from kazzylen_currency_switcher to ksmc_currency_switcher to match the ksmc_ plugin prefix * Fix: Admin page slug renamed from kazzylen-smc to ksmc-currencies to match the ksmc_ prefix * Fix: Enqueue hook detection updated to use ksmc-currencies page slug * Add: Restored world currencies selector (70+ currencies) in Add Currency modal * Add: Restored Add/Delete/Set Base buttons and full AJAX handlers * Update: Version 1.0.5, Stable tag 1.0.5 #### 1.0.4 * Fix: Removed save(insert), delete(), and set_default() methods from KSMC_Currencies entirely — these methods implied the ability to add/remove currencies which WP. org flagged as restricted functionality; renamed save(update) to update() to be unambiguous * Fix: Removed data-world-currencies.php (155-currency dataset) — no longer needed since add currency is not a feature of this plugin * Fix: Removed world_currencies from wp_localize_script output * Fix: Strengthened External Services readme section with explicit ToS/Privacy links and clearer data disclosure for both Frankfurter and ExchangeRate-API * Update: Version 1.0.4, Stable tag 1.0.4 #### 1.0.3 * Fix: Cart and checkout totals not converting on the WooCommerce Cart/Checkout BLOCKS — item price converted correctly but subtotal/total stayed in base currency with the new currency symbol applied. Root cause: block cart/checkout reads totals via the WooCommerce Store API, which bypasses classic display filters (woocommerce_cart_subtotal, woocommerce_cart_item_price, woocommerce_calculated_total) entirely. Removed the remove/restore filter pattern around cart calculation so WooCommerce always computes totals from the already-converted product price — this is read correctly by both classic templates and the Store API. * Fix: Short description in readme.txt trimmed to under 150 characters #### 1.0.2 * Change: Removed the 3-currency add limit per WordPress.org guidelines — the free plugin now ships with USD, EUR and GBP pre-installed; no add/delete UI needed * Fix: Text domain updated from kazzylen-smc-free to kazzylen-smart-multi-currency- for-woocommerce to match plugin slug * Add: External Services section in readme documenting frankfurter.app and open. er-api.com usage * Fix: Admin menu capability corrected — manage_woocommerce when WC active, manage_options otherwise; prevents “not allowed” error on rates/settings tabs * Fix: Cart/checkout conversion rewritten to use cart display hooks instead of remove/add_filters; fixes base price showing with wrong symbol in cart #### 1.0.1 * Fix: Cart and checkout showing base currency amount with converted symbol * Fix: All text domain mismatches resolved * Fix: Admin menu page access errors fixed * Add: Country selector in currency modal * Add: 155-currency world data file #### 1.0.0 * Initial release ## Meta * Version **1.1.1** * Last updated **4 weeks ago** * Active installations **Fewer than 10** * WordPress version ** 6.4 or higher ** * Tested up to **7.1.2** * PHP version ** 8.0 or higher ** * Tags * [currency](https://wordpress.org/plugins/tags/currency/)[currency switcher](https://wordpress.org/plugins/tags/currency-switcher/) [exchange rate](https://wordpress.org/plugins/tags/exchange-rate/)[multi currency](https://wordpress.org/plugins/tags/multi-currency/) [woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/kazzylen-smart-multi-currency-for-woocommerce/advanced/) ## Ratings No reviews have been submitted yet.
