CZ.NIC, z.s.p.o.

CZ.NIC, z.s.p.o. is the Czech national registry and internet governance body best known for operating the .cz top-level domain, yet it also develops open-source tools that help citizens and businesses interact securely with Czech public administration. Its small but focused software catalog centers on Datovka, a lightweight cross-platform desktop client that connects to the country’s mandatory data-box system. Through an intuitive Qt interface the program downloads official correspondence, verifies digital signatures, archives messages in a local SQLite store, and exports documents in standard formats, giving users offline access to tax statements, court writs, trade-register filings and other legally binding papers without repeatedly logging into the government web portal. Advanced features include full-text search, custom labels, automatic backups, and HTTPS or VPN tunneling for extra privacy, making the utility equally attractive to law firms, accountants, municipal clerks and individual entrepreneurs who must retain digital records for statutory periods. Because Datovka is released under the EUPL license, community contributors regularly audit the code and provide builds for Windows, macOS and most Linux distributions, ensuring long-term transparency and compatibility. The publisher’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always pull the latest upstream version, and can be queued for unattended batch installation alongside other applications.
