Kazzylen Smart Multi-Currency for WooCommerce

Kazzylen Smart Multi-Currency gives your WooCommerce store multi-currency support the moment you activate it. Three currencies (USD, EUR, GBP) come pre-installed, and you can add any additional currency you need. No API key required.

What’s included

• Shortcode — [ksmc_currency_switcher] — place the switcher anywhere on your site
• WordPress widget — drag the switcher into any widget area
• 3 switcher styles — dropdown, list, or pill buttons
• Free rate fetching — one-click “Fetch Live Rates” powered by frankfurter.app and open.er-api.com (no API key required)
• Manual rate entry — set your own exchange rates at any time
• Cookie-based session — visitor currency choice is remembered across pages and visits
• URL switching — ?currency=EUR works for direct links
• Clean uninstall — removes all plugin data on deletion

External Services

This plugin optionally connects to two free external APIs to fetch live exchange rates. These connections only occur when an admin manually clicks “Fetch Live Rates” in the Exchange Rates tab. They are never triggered automatically or on the frontend.

1. 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.
