Open data commitment

Public data should stay public.

Official business data in Europe is public by law, but rarely easy to use. National registers publish it as raw open data; our registry platforms turn it into fast, searchable public websites — and never put it back behind a paywall.

No paywall

Free, without conditions

No accounts, no subscriptions, no usage caps. Every profile, financial statement and filter on ČeskáData.cz, SlovakData.sk and CHdata.ch is available to anyone, permanently.

Provenance

Sources named on every page

Each platform states exactly which official registers it is built on — from the Czech Statistical Office and the Statistical Office of the Slovak Republic to the Swiss Federal Office of the Commercial Registry — and links to them directly.

EU framework

Aligned with European open-data policy

We re-use public-sector information in the spirit of the Open Data Directive (EU) 2019/1024. Company and company-ownership data is a designated high-value dataset category under EU law — we believe access to it should reflect that status.

Licensing

Open licences, attribution kept

Source registries are credited throughout, national open-data terms are respected, and re-published data carries open licences where applicable — for example CC BY 4.0 on SlovakData.sk.

6.3M+ records · 3 national registries · 0 paywalls — and it stays that way
