This Cookie Policy explains how Marc Dalmau Ballester (“we”, “us”, “our”), acting as a self-employed professional (“Autónomo”) and operator of MTGMASTER.AI (“the Service”), uses cookies and similar technologies in compliance with the General Data Protection Regulation (GDPR), the ePrivacy Directive, and Spanish LSSI-CE (Law 34/2002).

If you do not agree with the use of optional cookies, you may reject them or manage your preferences as described below.

1. What Are Cookies?

The Service does not embed third-party content that automatically sets tracking cookies without user interaction.

4. Cookie Consent Banner

When you first visit the Service (where legally required), you will see a cookie banner that allows you to:
