### External services

This plugin uses [Private Captcha](https://privatecaptcha.com) API to request and
verify captcha challenges and their solutions, when protection is enabled on user-
configured forms.

When solving of the captcha widget challenge begins, a new challenge is requested
from Private Captcha API. When submitting the relevant form (e.g. Comment Form or
Login Form), challenge solution is sent to Private Captcha API.

During requesting challenges or verifying solutions, no Personal Data (within meaning
of Art. 4 (1) GDPR) is neither collected, nor sent. Check all relevant information
in the Private Captcha’s [Privacy Policy](https://privatecaptcha.com/legal/privacy/).
