This document discusses the GDPR, ePrivacy Regulation, and how they impact online tracking and consent requirements. Key points include: - GDPR allows for consent (opt-in) or legitimate interest as a legal basis, while ePrivacy Regulation requires opt-in consent. - Germany in particular has not fully implemented the ePrivacy Directive and still requires opt-in consent under local law. - The document discusses an "OIL" solution that can forward opt-out/opt-in preferences through advertising technology to give users control over tracking. - Several large European publishers have implemented or contacted the company about the OIL solution.
