Czech Republic
AI behavior law: bot and agent disclosure, crawler and training-data rules, automated-agent transactions, and algorithmic decision-making.
Summary
Czechia transposed the DSM Directive via Act No. 429/2022 Coll., in force 5 January 2023, introducing §39c (research TDM) and §39d (general/commercial TDM with machine-readable opt-out) into the Czech Copyright Act (autorský zákon, Act No. 121/2000 Coll.). A robots.txt or similar machine-readable reservation triggers the opt-out under §39d. Czechia has the full EU sui generis database right (Act No. 562/2006 Coll., zákon o ochraně databází). Computer crimes are governed by trestní zákoník §230 (unauthorized access to a computer system), which requires overcoming a security measure — public pages without technical protection fall outside its scope. GDPR applies with the ÚOOÚ (Úřad pro ochranu osobních údajů) as DPA. The EU AI Act is binding from August 2025. No scraping-specific Czech court decisions have been identified.
