<h3>External Services</h3>
<p>This plugin relies on the Payment4 API, a third-party external service, to process cryptocurrency payments. The plugin will not function without connecting to this service.</p>
<h4>What is the Payment4 API?</h4>
<p>Payment4 (https://payment4.com) is a cryptocurrency payment gateway service that processes crypto transactions, monitors blockchain confirmations, and manages payment verification.</p>
<h4>When does the plugin connect to Payment4 services?</h4>
<p>The plugin connects to Payment4 external services in the following situations:</p>
<ol>
<li><strong>During Checkout</strong> – When a customer selects Payment4 as their payment method and proceeds to pay</li>
<li><strong>Payment Verification</strong> – When verifying that a cryptocurrency payment has been received and confirmed on the blockchain</li>
<li><strong>Payment Callbacks</strong> – When Payment4 sends webhook notifications about payment status updates</li>
<li><strong>Language Files</strong> – When loading translation files for the plugin interface</li>
</ol>
<h4>What data is transmitted?</h4>
<p>When processing payments, the following data is sent to Payment4 services:</p>
<ul>
<li>Order amount and currency</li>
<li>Order ID and description</li>
<li>Customer email address (optional, for payment notifications)</li>
<li>Return and callback URLs for your website</li>
<li>API credentials (API key) for authentication</li>
</ul>
<p>No sensitive financial information (credit card details, bank accounts, etc.) is transmitted. Cryptocurrency transactions are handled directly on the blockchain.</p>

Kudos to the developer for creating an optimized free alternative for the paid version of a similar extension by EDD. Although the plugin still works well with the latest WordPress 5.3.2, PHP 7.3.12, EDD 2.9.22, I believe the developer should release an update just to be on the safe side, making sure there are no errors happening on the back-end & also so that the wordpress repository stops showing the plugin hasn't been updated in the last 3 years.

Great plugin & a free alternative to EDD's paid extension
