PS PHPCaptcha WP

Simple PHP-GD based captcha to replace tracking prone systems like Google recaptcha

Description

PS PHPCaptcha WP does not use any remote resources. This makes it fully GDPR compliant without any need to mention it in your privacy policy.

To generate the image this plugin does not need to use the Wordpress database and therefore IO of the database is very low. This very important if you run a site with high traffic.
