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