Brazil advances LGPD bills on platforms

Update September 21, 2026: Brazil’s Chamber of Deputies is still considering the executive branch’s big tech bill, which is listed as ready for floor debate, and there is no formal decision to postpone it to 2027. The bill that would amend the LGPD to let users turn off algorithms on social networks and choose a chronological feed also remains unvoted.

Brazil still has at least two legislative tracks moving that affect data protection and the use of algorithms on platforms. In the Federal Senate, PL 145/2024 has remained in the Committee on Transparency, Governance, Oversight and Control, and Consumer Defense since June 26, 2024. Since August 9, 2024, it has also been waiting for a rapporteur to be assigned. In the Chamber of Deputies, another bill would let users disable the algorithm and opt for a chronological feed, while also tightening rules for behavioral and advertising profiling.

What would the bill on social networks and algorithms change?

The bill introduced in the Chamber of Deputies would amend the LGPD to give social media users the right to turn off the algorithm and choose a chronological feed. It also reclassifies profiling data as sensitive personal data and requires explicit consent to create behavioral profiles.

The proposal, introduced by federal deputy Fernanda Melchionna, also bans reliance on legitimate interest as a legal basis for that profiling. According to the coverage cited, it would also prohibit the sale or sharing of that data with third parties for economic gain. The bill has not yet been voted on, so current platform algorithm rules remain in force.

How does it affect minors, and what framework complements it?

The same bill also amends child protection law to fully prohibit profiling of children and adolescents for content recommendation or targeted advertising. The LGPD would serve as a complementary rule to cover any gaps.

That point connects with the Digital Child and Adolescent Statute, Law No. 15.211/2025, which Data Privacy Brasil identifies as the ECA Digital and which enters into force on March 17, 2026. The organization released materials on age assurance and manipulative design, a regulatory context that helps explain the restrictions on profiling minors in digital environments.

What other legislative moves appear in the LGPD?

Senator Lucas Barreto, of PSD-AP, is listed as the author of proposals to amend the LGPD regarding the composition of the National Council for Personal Data Protection and Privacy. His profile on Congresso Quanta notes that the initiative seeks to amend Law No. 13.709/2018 to address that composition.

That detail shows that the debate in Brazil is not limited to platform behavior. It also includes the institutional governance of data protection and how the national council that oversees that system is structured.

What place does the AI agenda have in that discussion?

Artificial intelligence regulation is also tied to this broader map. StartSe reported that, in December 2025, the National Data Protection Authority published a Priority Topics Map that includes AI and emerging technologies as one of four enforcement pillars for the biennium.

According to that coverage, the focus is on transparency, bias mitigation, data security, and compliance with Article 20 of the LGPD on review of automated decisions. At the same time, Senate bill PL 145/2024 is still moving through the process without a rapporteur assigned, amid a legislative agenda that mixes data governance, transparency, and oversight of emerging technologies.

Executive Branch bill PL 4,675/2025 is moving through the Chamber of Deputies under urgent procedure and is formally ready to be considered by the floor. Café com Bytes reported that the official record lists it as "Pronta para Pauta no Plenário" and "Aguardando Despacho do Presidente da Câmara dos Deputados".

The same coverage said there is no formal decision to push the bill to 2027 and that, in legal terms, it remains under consideration and can be placed on the Chamber’s agenda. That adds a third piece to Brazil’s debate over platform regulation, big techs, and data governance.
