About Private Captcha

Private Captcha is a privacy-first CAPTCHA service designed to block bots without hindering real users. It protects forms and APIs with an invisible cryptographic task that runs in the background and scales difficulty to match traffic. All infrastructure and suppliers are EU-based, the code is publicly auditable, and you can self-host for full data control. There is no end-user tracking, no cookies, and no personal data processing.
