Both are effective against automated bots while remaining accessible to humans.

<h3>Privacy & Data Collection</h3>
What Data Does This Plugin Collect?
SecureGate Captcha Lite is designed with privacy as a core principle:
Stored Locally (in your WordPress database as transients): 
* Anonymized IP addresses (last octet removed)

* Success/failure status of CAPTCHA verifications 
* Failed attempt counters for rate limiting
NOT Stored: 
* User emails or usernames 
* Personal identifying information 
* Browser fingerprints 
* Tracking cookies (plugin-side) 
* Permanent user profiles
External Service Data: 
When Cloudflare Turnstile is enabled, user browser data is sent to Cloudflare for bot detection. Please review <a href="https://www.cloudflare.com/privacypolicy/" rel="nofollow ugc">Cloudflare’s Privacy Policy</a> for details.
When using the Built-in CAPTCHA, NO external services are contacted.
Data Retention: 
All logs are stored as WordPress transients and automatically deleted after 7 days. Administrators can disable logging entirely in settings.
Right to Erasure: 
No personal data is collected that would require manual erasure requests under GDPR.
