Data Localization Strategies for Flutter Applications

This technical report explores practical strategies for implementing data localization in Flutter-based mobile applications. As global privacy regulations increasingly mandate that personal data be stored within specific jurisdictions, mobile developers must adopt architectural patterns and technical mechanisms that ensure compliance. The report presents a structured approach to designing Flutter apps that enforce regional data residency, optimize performance, and maintain user trust. It also includes implementation examples and a case scenario of a health app designed to comply with India’s DPDP Act.
