<h4>Privacy & Data</h4>
<p>SMSKora stores SMS log records (recipient, message status, provider, context) and OTP records (hashed OTP, phone, expiry) in custom database tables. No data is sent to third-party servers by this plugin. Data is sent only to the SMS gateway you configure. All stored data is deleted when the “Delete Data on Uninstall” setting is enabled.</p>
<h3>External services</h3>
<p>SMSKora connects to external SMS gateway APIs only when a site administrator configures an SMS provider and the plugin sends an SMS message, OTP message, order notification, login verification message, registration verification message, or balance-check request.</p>
<p>The plugin does not send SMS data to servers controlled by the SMSKora plugin author. SMS data is sent only to the SMS gateway provider selected and configured by the site administrator.</p>
<p>For configured providers, the following data may be sent to the selected provider:</p>
<ul>
<li>Recipient phone number.</li>
<li>SMS message body.</li>
<li>Sender ID or sender number, if configured.</li>
<li>API key, access token, username, password, or other gateway credentials required by the provider.</li>
<li>Request metadata required by WordPress and the remote API, such as the site server IP address and HTTP request headers.</li>
<li>For balance-check requests, the plugin sends the configured API credentials to the selected provider to retrieve the account balance.</li>
</ul>
<p>No external SMS gateway request is made unless the administrator configures a provider and a plugin feature triggers an SMS send or balance check.</p>
