External service
This plugin relies on Yandex SmartCaptcha, a third-party service operated through Yandex Cloud. The SmartCaptcha JavaScript is loaded from https://smartcaptcha.cloud.yandex.ru/captcha.js on pages where a protected CAPTCHA widget is rendered. When a protected form is submitted, the CAPTCHA token and, when available, the visitor IP address are sent server-side to https://smartcaptcha.cloud.yandex.ru/validate together with the site owner’s private server key to verify the request.
A Yandex Cloud account and a configured SmartCaptcha are required. Review the service documentation and applicable legal terms before enabling the plugin:
