<h3>External Services</h3>
This plugin connects to the following external third-party services. No external connections are made for core PDF signing functionality — all PDF processing happens locally on your server.
<h4>Freemius (freemius.com)</h4>
This plugin uses the Freemius SDK for license management and premium feature activation. When the plugin is activated, it connects to the Freemius API to register the site and validate license status.
<ul>
<li>What data is sent: Site URL, plugin version, WordPress version, PHP version, and admin email address (if the admin opts in to usage tracking).</li>
<li>When data is sent: On plugin activation, during periodic license validation checks, on update checks, and optionally for anonymous usage analytics (only if the admin explicitly opts in).</li>
<li>Why: To manage premium license activation, enable premium features, and provide support services.</li>
<li>Service provider: Freemius Inc.</li>
<li>Terms of Service: https://freemius.com/terms/</li>
<li>Privacy Policy: https://freemius.com/privacy/</li>
</ul>
<h4>WordPress.org API (api.wordpress.org)</h4>
This plugin connects to the WordPress.org API solely for a network connectivity diagnostic test. This is only triggered when an admin manually clicks “Run Diagnostics” on the License settings page.
<ul>
<li>What data is sent: A standard HTTP GET request with default WordPress HTTP headers (site URL, WordPress version).</li>
<li>When data is sent: Only when an administrator manually initiates a diagnostics check from the plugin License page.</li>
<li>Why: To verify the server can make outbound HTTPS connections, which is required for license validation.</li>
