One person writes and checks these guides, and reads everything that comes back.
Something on a guide is wrong
This is the most useful message you can send. Every guide carries a “Report a change” button beside the section it belongs to - that route is quickest, because it arrives already attached to the page and the category you were reading.
If you would rather write, use ondra.kadlec@email.cz and say which page it is. Corrections are made by hand against the operator or the authority, and the verification date on the page moves when they are.
Your account or your data
Export and deletion are self-service on the Account page. For anything else - a correction to your own data, an objection, a question about what is stored - the same address reaches the data controller, and Privacy sets out what those rights are.
Anything else
Partnerships, press, a country you would like covered: ondra.kadlec@email.cz. There is no form here on purpose - it would be one more thing collecting data.
Who is behind the site and how it pays for itself is on About.
