Datovka is a multiplatform desktop application for accessing data boxes. A data box is an electronic storage site in Czech Republic. It is intended for delivery of official documents and for communication with public authority bodies.
Datovka allows receiving, sending, and checking the integrity of data messages, exporting proofs of delivery or full messages, exporting complete correspondence for a defined period, etc.
The user interface resembles the interface of common e-mail clients.
This flatpak is not maintained by CZ.NIC, z.s.p.o.
