Data localization refers to the requirement that personal data must be physically stored and processed within the geographic boundaries of the country or region where it was collected. This concept is increasingly prevalent in modern privacy and data protection laws, such as the GDPR, China’s Cybersecurity Law, and Brazil’s General Data Protection Law (LGPD). Data localization aims to ensure that personal data remains subject to the jurisdiction’s specific data protection regulations and doesn’t cross borders without appropriate safeguards.
