What they are
Cookies are small files the site stores in your browser. Some are necessary for the store to work (buying, paying, viewing your purchase) and others measure and improve our ads.

For visitors in the European Union, analytics and advertising cookies (Meta Pixel and Microsoft Clarity) are only activated after you accept them in the banner, which offers “Accept” and “Reject” with equal prominence (art. 5(3) Directive 2002/58/EC). You can change your choice at any time from Cookie settings.
