Overview

Spain-specific requirements to plan for

Projects for businesses in Barcelona have to work for local customers and local rules. These points are planned from the first milestone:

  • Channels that matter most in Spain: Instagram, WhatsApp, TikTok and LinkedIn.
  • GDPR and the LOPDGDD (Organic Law 3/2018): The LSSI requires a legal notice (aviso legal) and consent for non-essential cookies.
  • Interface and content languages: Spanish and Catalan, Basque and Galician regionally.

This is practical delivery guidance, not legal advice.
