Vivodepot

Vivodepot is an open-source application that lets people keep their personal records themselves: advance directives, health, finances, housing, education and work. The depot is stored encrypted on their own device. No account is needed, and the application does not send anything from the depot.

Vivodepot is an offline-first, single-file HTML application for citizen-side health and civic data management. It runs in any modern browser without installation. Data is stored locally in an AES-256-GCM encrypted container with PBKDF2 key derivation — no cloud dependency, no server infrastructure, no account registration. The application is opensource under EUPL-1.2 and available at vivodepot.de.

The Yellow Button is integrated into the Vivodepot application itself. The citizen opens her local Vivodepot file in any browser; Yellow Button functionalities are part of the standard workflow. No separate app, no portal account, no platform dependency.
