Uma Caracterização das Polı́ticas de Privacidade Utilizadas em Aplicativos no Brasil

Privacy policies are documents in which technology companies specify how personal data from their users are processed. In Brazil, the agreement between companies and users is regulated by law. So, it is important to users to be able to easily access and understand such documents. In this work, we study privacy policies from more than 1,000 apps from Google Play Store. We show that many of these apps provide invalid documents and only approximately 10% of them contain privacy policies in Portuguese. Furthermore, none of the considered documents have an adequate degree of readability and will be incomprehensible for large parts of the Brazilian population.
