GDPR Compliant Captcha

ALTCHA is GDPR Compliant

The self-hosted ALTCHA is fully compliant with GDPR by design and without the need to update your privacy policy as it doesn’t use cookies or external services.

If you’re using the API, please refer to the API GDPR Guidelines.

ALTCHA aims to provide robust security measures while ensuring adherence to General Data Protection Regulation (GDPR) guidelines by eliminating the use of cookies and fingerprinting.

Unlike traditional captcha methods that rely on cookies or fingerprinting, ALTCHA does not employ these techniques. By avoiding the use of cookies, ALTCHA ensures that user data isn’t tracked, stored, or shared without explicit consent, aligning with GDPR’s emphasis on user privacy.


  • Cookie-less solution means there’s no need for a cookie banner.
  • Without reliance on external servers or services.
  • Mitigates the risk of legal repercussions and fines associated with GDPR.
  • Enhances trust and user confidence.

Comparison to reCAPTCHA and hCaptcha

While reCAPTCHA and hCaptcha offer varying levels of bot protection, their data collection practices and reliance on tracking mechanisms raise privacy concerns and pose challenges for GDPR compliance, necessitating user consent before implementing such solutions. In contrast, ALTCHA stands out as a privacy-centric solution, providing seamless bot protection without compromising user privacy or accessibility.
