Czech DPA issues guide for cookie disclosure
The Czech Republic’s data protection authority, the Úřad pro ochranu osobních údajů, published guidance on cookie disclosures for web operators. The guide states web operators must disclose if their website uses "non-technical cookies" that collect visitor’s personal data. However, the use of technical cookies does not necessitate introducing a cookie bar on those websites as long as there is visible documentation explaining what types of data they collect.
