This guide contains the text of the policy letter Personal data management, sent by the Cabinet to the Dutch House of Representatives on 11 July 2019. In that letter, the Cabinet describes how a citizen can gain greater control over the personal details stored about him or her by the government. By being given access to and being able to (call for) the rectification of his or her details. By no longer having to issue any details the government already has in its possession. And by allowing the digital sharing of details by government with private service providers (such as housing corporations, health care providers, mortgage suppliers or the church). We wish you every possible inspiration in reading this guide!
