<h3>Privacy</h3>
<p>This plugin uses an optional opt-in to collect <strong>non-sensitive diagnostic data</strong> and plugin usage information to help improve the product. The opt-in is presented on first use and can be changed at any time under <strong>Authica <span aria-hidden="true" class="wp-exclude-emoji">→</span> Account</strong>.<br />
Collected data may include: WordPress/site version, language, plugin/theme list and versions, admin email (for license/updates), and anonymized site URL. <strong>No personal content or passwords are collected.</strong></p>
<p>Data is processed by our licensing/telemetry provider and by us for support and update delivery.<br />

<h3>External services</h3>
<h4>Cloudflare Turnstile (human verification)</h4>
<p>This plugin can integrate with Cloudflare Turnstile to protect login, registration, and password-reset forms from automated abuse.</p>
<p>• What is it used for?<br />
  Turnstile provides a human verification widget to reduce bot signups and credential-stuffing attempts.</p>
<p>• What data is sent and when?<br />
  – On pages where the widget is shown, the Turnstile JavaScript file is loaded from<br />
    https://challenges.cloudflare.com/turnstile/v0/api.js. When loaded, Cloudflare<br />
    may receive standard browser/connection data (e.g., IP address, user agent, referrer)<br />
    and evaluate device/browser signals to determine risk, per Cloudflare’s documentation.<br />
  – When a verification token is produced by the widget, your WordPress site makes a<br />
    server-to-server request to:<br />
      https://challenges.cloudflare.com/turnstile/v0/siteverify<br />
    The server-to-server verification includes the user’s response token and your secret key.<br />
    When a valid client IP is available, the optional remoteip value may also be sent to Cloudflare to improve verification accuracy.</p>
<p>• Where can I learn more?<br />
  – Cloudflare Turnstile: https://www.cloudflare.com/products/turnstile/<br />
  – Turnstile docs: https://developers.cloudflare.com/turnstile/<br />
  – Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/<br />
  – Cloudflare Terms of Service: https://www.cloudflare.com/terms/</p>
<p>• How do I disable it?<br />
  Turnstile integrations can be disabled at <strong>Authica <span aria-hidden="true" class="wp-exclude-emoji">→</span> Turnstile & Edge Security</strong>, which stops the<br />
  widget from loading and the verification endpoint from being called.</p>
<h4>jsDelivr (Chart.js fallback, admin-only)</h4>
<p>For the admin “Captcha Statistics” chart, this plugin prefers a local copy of Chart.js<br />
(bundled in <code>assets/vendor/chart.js/</code>). If the local file is not present, it falls back to<br />
loading Chart.js from:<br />
  https://cdn.jsdelivr.net/npm/chart.js@4.4.3/dist/chart.umd.min.js</p>
<p>• What data is sent?<br />
  Only the administrator’s browser requests the static script file from the CDN.<br />
  No user content or personal data is transmitted by this plugin as part of that request.</p>
<p>• How do I avoid the CDN?<br />
  Keep the local file at <code>assets/vendor/chart.js/chart.umd.min.js</code> so the fallback is not used.</p>
<h4>Email delivery</h4>
<p>This plugin uses WordPress <code>wp_mail()</code> to send email verification messages. Mail delivery<br />
is handled by your hosting provider or any SMTP/email plugin you configure. If you connect<br />
a third-party email service (e.g., via an SMTP plugin), that service’s privacy terms apply.<br />
This plugin does not send verification data to any email vendor on its own.</p>
