Continuous Voter Data Updating shifts Indonesian voter-list governance from a predominantly episodic model toward data maintenance throughout the electoral cycle. This study examines the normative position of PDPB, its functional relationship with voter-list updating during formal election stages, and its implications for protecting voting rights. The study uses normative legal research with statutory, conceptual, and analytical approaches. Its principal legal materials include election legislation, KPU regulations on PDPB and voter-list preparation, population-administration law, personal-data-protection law, and Constitutional Court decisions concerning voting rights. The findings show that PDPB and election-stage updating are complementary rather than substitutive. PDPB maintains the voter database between elections, while election-stage procedures provide factual verification, correction, public scrutiny, and final legal establishment. The appropriate design is an integrated cycle linking population-data synchronization, field verification, Bawaslu oversight, public participation, and privacy safeguards. The article therefore reframes PDPB as a preventive constitutional-rights mechanism embedded in electoral governance. It also proposes an operational matrix for evaluating legal basis, institutional responsibility, verification, privacy protection, participation, and measurable performance indicators
