On 18 October 2021, the Amendment to the Electronic Communications Act (“ECA”) was promulgated in the Collection of Laws. The approved amendment to the ECA affects, i.a., the legal regulation of the use of cookies (and other similar technologies used to distinguish terminal devices of users) by introducing the need for active user consent for the use of most types of cookies. Anyone who places cookies on a user’s terminal device when operating a website or mobile application should therefore take care to check their settings for the use of cookies.
