Does FaceApp violate Brazilian law?
The General Data Protection Act, passed in 2018 and will only come into force in August 2020, would also conflict with the FacaApp application. The Brazilian law establishes some principles that should guide the activities of collection and processing of personal data, such as: purpose, adequacy, necessity and transparency, principles that are not compatible with policies as broad and generic as FaceApp.
It could also affect user consent, which needs to be offered based on specific, rather than generic, purposes. In any case, the right to privacy is guaranteed by the Federal Constitution and practices that violate it can be the object of questioning, including in the judicial scale.
