Ad targeting

New research from our partners at the Centre for Internet & Society (CIS) reveals Indian health websites and apps are sharing intimate health-related data with third parties such as Facebook and Google. 

Our 2018 complaint against French AdTech company Criteo led to a €40 million fine for failing to ensure that data subjects had provided their consent to processing, to sufficiently inform them and to enable them to exercise their rights.

Following on from our initial reaction, we answer some questions about the decision below.

Following its 2021 research on diet ads sharing personal data with third parties, PI ran a follow-up analysis of Noom's online test to assess changes and reflect on publishers' data sharing practices.

Companies selling diet programmes are using tests to lure users. Those tests encourage users to share sensitive personal data, including about their physical and mental health. But what happens to the data? We investigated to find out.

Privacy International investigates the use of personal data in political campaigning, focusing on the ecosystem of private companies hired by political parties, the policies of online platforms, and the laws that regulate micro-targeting around the world.

PI presents here 5 profiles of companies involved in political campaigning in order to provide a snapshot of how the digital political campaign sector works and further highlight the opacity and concerns for privacy.

Join us on a journey to try to solve the mystery behind the advertisers who have uploaded our personal data to Facebook but with whom we've never interacted with before.
