TikTok Rules in Brazil (2026): Age, Guardian Consent, LGPD & the Digital ECA

Brazil is the first country where a data-protection authority formally sanctioned TikTok — and 2026 is a turning point. A new child-and-adolescent digital statute, a landmark LGPD fine, and mandatory (non-self-declared) age verification make Brazil one of TikTok's strictest markets for minors. Sources throughout.

TL;DR — key takeaways

• Every under-18 user needs guardian involvement in Brazil (representation for 13–<16; assistance for 16–<18) — a Civil Code requirement baked into TikTok's Brazil Terms.
• ANPD fined ByteDance R$153.7 million on 25 August 2026 for children's-data failures under the LGPD.
• Self-declared age is illegal under the Digital ECA (in force 17 March 2026); platforms must use reliable age verification.
• All targeted/behavioral advertising to under-18s is banned nationwide — only contextual ads are lawful.
• The no-login "guest" feed is specifically restricted by ANPD (ads suspended, 12-hour cap, no posting/DM/LIVE, minimal data).

Quick reference

Is TikTok legal in Brazil?

Yes — available nationwide with no ban, but under escalating regulatory pressure. On 25 August 2026 the ANPD published a sanctioning decision fining ByteDance R$153.7 million for failures protecting children's and adolescents' data under the LGPD, and ordered a compliance plan plus heavy restrictions on the no-login experience. TikTok remains accessible while ByteDance's appeal proceeds. (ANPD press release)

What is the minimum age for TikTok in Brazil?

13 (the global baseline), but Brazil's supplemental Terms of Service deviate upward with mandatory guardian involvement for every minor: users 13 to under 16 may register only "with the representation of your parents or legal guardians," and users 16 to under 18 only "upon the assistance of your parent or legal guardian." This reflects the Brazilian Civil Code, under which minors lack capacity to contract alone — the ANPD explicitly rejected the idea that a minor's acceptance of terms was a valid legal basis.

Age verification — self-declaration is prohibited

Under the Digital ECA (Estatuto Digital da Criança e do Adolescente, Law 15.211/2025, in force 17 March 2026), platforms accessible to minors must use reliable age-verification mechanisms and self-declaration is expressly prohibited. Permitted approaches include algorithmic age estimation, documentary verification, or verified credentials, proportional to risk. For under-16 users, accounts must be linked to a verified legal guardian with supervision tools (time limits, contact restrictions, purchase approvals).

The LGPD fine and its basis

The LGPD (Lei Geral de Proteção de Dados, 13.709/2018) requires processing of children's/adolescents' data to serve their best interest and, for children, generally with specific parental consent (Art. 14). The ANPD's R$153.7M decision (published in the Diário Oficial da União, 25 Aug 2026) cited violations across LGPD Arts. 6 and 7 — processing minors' data without a valid legal basis in both the no-login and registered feeds, failing to prevent minor access/registration, and failing to demonstrate effective safeguards — reportedly one of ANPD's first large fines against a major platform.

Content & advertising rules (strict for minors)

• No targeting under-18s: The Digital ECA bans behavioral advertising and profiling of anyone under 18 — only contextual advertising is allowed. It also bans emotional-analysis techniques and immersive AR/VR/XR ad tools aimed at minors.
• The no-login feed is capped: ANPD ordered TikTok to suspend ads, restrict content to age-appropriate material, apply a 12-hour usage limit, disable posting/DMs/LIVE, and collect minimal data for unregistered users.
• Child-directed advertising is "abusive": Under CONANDA Resolution 163/2014 + the ECA (8.069/1990) + the Consumer Protection Code, advertising directed at children up to 12 is treated as illegal — relevant to branded content, product placement and child creators ("influenciadores mirins"). (Gala Law, ECA Law 8.069/1990 – Planalto (official text))
• Self-regulation (CONAR) adds ethical limits on child-directed commercial communication.

What creators & brands should do

1. Assume guardian involvement is required for any under-18 audience or creator.
2. Use only contextual ads for minors — behavioral targeting of under-18s is unlawful.
3. Do not rely on self-declared age in age-sensitive campaigns.
4. Be cautious with child-creator content — "abusive advertising" liability is real under CONANDA 163/2014.

Accuracy & limitations

The load-bearing claims are backed by primary sources (ANPD press release, gov.br news agency, TikTok ToS) and strong law-firm/policy analysis of Law 15.211/2025. Two cautions: the claim that this was ANPD's first Big-Tech sanction is softened here (not stated in the ANPD release); and the Digital ECA's "10% of Brazil group revenue" penalty ceiling was not confirmed against the primary statute (only R$50M/violation was) — treat that ceiling as unverified. Exact article numbering of Law 15.211/2025 and Decree 12.622/2025 rests on secondary sources. Reliability: high on the core facts.
