Our self-hosted CAPTCHA system offers two challenge types:
– Math Challenges: Simple arithmetic problems (e.g., ”What is 7 + 3?”)
– Text Recognition: Warped text characters requiring human recognition

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

Privacy & Data Collection

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):

NOT Stored:

* 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 Cloudflare’s Privacy Policy 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.
