This book constitutes the refereed proceedings of the 12th Annual Privacy Forum on Privacy Technologies and Policy, APF 2024, held in Karlstad, Sweden, during September 4–5, 2024. The 12 full papers were carefully reviewed and selected from 60 submissions. This conference was established as an opportunity to bring together key communities, namely policy, academia, and industry, in the broader area of privacy and data protection while focusing on privacy-related application areas. Like in the previous edition, a large focus of the 2024 conference was on the General Data Protection Regulation (GDPR) and the emerging legislation around the European Data Spaces and Arti cial Intelligence. Chapter 3, 9, 12 are licensed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/).
