DKB, short for Deutsche Kreditbank AG, is a digitally focused German retail bank. It offers a current account with a mobile app, and its main product is the DKB-Cash current account. The bank serves private customers and some business and public-sector clients, with only a few branches. Customers can open accounts and sign mortgage contracts digitally, through a hosted online banking platform. The bank states that its focus is on the digitalisation of banking.
Deutsche Kreditbank AG is seated in Berlin and wholly owned by Bayerische Landesbank, a German state bank, so the ownership chain stays in Germany and the EU. The bank's website does not state where customer data is hosted, so a European organisation should confirm hosting and data-processing terms in writing. As a proprietary banking platform, DKB offers no open-source or self-hosting option, so the sovereignty question rests mainly on contractual safeguards.
