In the sixth grade, at the age of 12, Amaral participated in the 2005 edition of the Brazilian Public School Mathematics Olympiad (OBMEP), and won a silver medal on her first attempt.

[11] The following year, due to her gold medal and strong academic performance, she obtained a full scholarship at Colégio ETAPA, a private school in São Paulo, where she completed her secondary education.

[3] The organisation crowd-sourced concerns about education among young people in Brazil, and then questioned candidates on those education-related issues during the 2016 Brazilian municipal elections, disseminating their responses widely on social media.

[29] As a result, in September 2021, Amaral announced that she had left the PDT to join the PSB (Partido Socialista Brasileiro ~ Brazilian Socialist Party).

[30] In July 2019, the magazines Veja[31] and Exame[32] revealed that Amaral hired her then-boyfriend, Daniel Alejandro Martínez, to work on her 2018 election campaign.

[31] According to the Superior Electoral Court, Amaral spent 23,000 reais (at the time about 6,000 USD[33]) from the public election fund to pay for these services, which were provided between August and October 2018.

[35] In another case, the Supreme Federal Court had previously ruled that hiring relatives or spouses with electoral funds is legal,[36] but the practice has been widely condemned by journalists and commentators.

[39] Beginning in 2019, Amaral has been in a relationship with fellow Socialist Party member, former federal deputy from the state of Pernambuco, and current mayor of Recife João Henrique Campos.
