In this session, we will examine real-world evidence of data-harvesting practices used by TikTok and Meta, as identified by the Jscrambler research team.
Our analysis will break down the technical aspects of how these data collection methods operate, including how pixels can bypass consent systems and turn "anonymous" browsing into persistent user profiles. Additionally, we will provide technical strategies to help regain control on the client side without compromising business performance.
