  abstract = {There is a discrepancy in the contractual relationship of online terms of use (ToS), as supplier companies impose a series of clauses on their consumers. Some studies have already proven that it is possible to detect potentially non-compliant clauses with European consumer legislation. However, the work carried out to date has largely focused on European legislation and English-language documents. In this work, we present an annotation guideline that maps Brazilian consumer legislation into 10 categories and 3 levels of potential compliance. We also introduced a corpus in Portuguese, with clauses annotated from the guideline. We analyzed the performance of a classifier trained with our corpus and obtained results similar to initial studies in English for the tasks of detecting potentially non-compliant clauses and categorizing potential non-compliant clauses. The results of our work highlight a promising path to developing methods capable of analyzing ToS in Portuguese, and which can be replicated to other fields of Consumer Law.},
