<li><strong>Usage analytics</strong>: Anonymous local tracking of which features are used</li>
<li><strong>Deactivation survey</strong>: Optional one-question survey when deactivating</li>
</ul>
<p><strong>Local Storage</strong>: All feedback is always stored locally in your WordPress database.</p>
<p><strong>Optional Remote Sending</strong>: You can opt-in to send anonymous feedback to the developer to help improve TaxDebug. This is <strong>disabled by default</strong> and must be explicitly enabled in Settings.</p>
<h4>What IS Sent (When Opted-In)</h4>
<ul>
<li>Anonymous store UUID (random identifier, NOT your domain)</li>
<li>Feedback type and message</li>
<li>Your email (only if you voluntarily provide it)</li>
<li>Store country and currency</li>
<li>Active tax plugin (e.g., TaxJar, Avalara)</li>
<li>Plugin, WordPress, and WooCommerce versions</li>
<li>Daily aggregated counts: orders logged, issues detected, features used</li>
</ul>

<li>Customer names, emails, or addresses</li>
<li>Order details, totals, or line items</li>
<li>Tax amounts or financial data</li>
<li>Any personally identifiable information (PII)</li>
</ul>
<h4>How to Disable Remote Sending</h4>
<p>Go to <strong>WooCommerce <span aria-hidden="true" class="wp-exclude-emoji">→</span> TaxDebug <span aria-hidden="true" class="wp-exclude-emoji">→</span> Settings</strong> and turn off “Send Anonymous Feedback”. You can do this at any time. Local feedback storage will continue to work.</p>
