01Brazilian law applies to services offered in Brazil
The Brazilian Internet Act applies Brazilian law to data collection and processing when at least one device is in Brazil, including for foreign companies that offer services to the Brazilian public (art. 11). Its article 8 voids adhesion clauses that do not offer users a Brazilian forum for disputes about services provided in Brazil. Terms that only point to Delaware or California courts will not stop a Brazilian user from suing at home.
02Consumer law is the main source of disputes
When the user is a consumer, the Consumer Defense Code applies. It requires clear information in Portuguese (art. 31), voids clauses that waive consumer rights (art. 51) and requires limitations of rights to be highlighted (art. 54). Consumers can file complaints with the Procons, on the consumidor.gov.br platform and in small claims courts at low cost. Clear terms and a working cancellation flow prevent most of them.
03Free trials, auto renewal and the 7 day withdrawal
Article 49 of the CDC gives consumers 7 days to withdraw from purchases made outside a physical store, which includes online subscriptions, with a refund of amounts paid. The E-commerce Decree 7,962/2013 adds mandatory seller information and support duties. For subscriptions, the safest design is a renewal reminder, a visible cancellation option and terms that describe exactly what the checkout does.
04B2B is more flexible, but not free of rules
Contracts between companies benefit from freedom of contract and a presumption of parity (Civil Code, arts. 421 and 421-A). Liability caps, SLAs and auto renewal are generally accepted when clearly agreed. Small business customers may still claim consumer protection when they are vulnerable compared to the provider, so B2B terms aimed at very small companies deserve extra care.
05The LGPD comes with the product
A SaaS that collects personal data from users in Brazil is subject to the LGPD, even if the data is hosted abroad. That means a Portuguese privacy notice, legal bases for each purpose, an encarregado (DPO), a request channel and, for data leaving Brazil, a valid transfer mechanism.
06Local entity, payments and taxes
Many SaaS companies start selling to Brazil from abroad and open a Brazilian entity later. The choice affects invoicing, local payment methods such as Pix and boleto, withholding taxes paid by Brazilian business customers and which party appears in your terms. We flag these points so your accountant and tax advisor can confirm the structure.
07Products used by children: the Digital ECA
Since March 17, 2026, the Digital Statute of Children and Adolescents (Law 15,211/2025) applies to digital products and services aimed at, or likely to be accessed by, minors in Brazil, including foreign ones. It requires age assurance, parental supervision tools and protective default settings, bans loot boxes in games aimed at minors and requires foreign providers to keep a legal representative in Brazil. Sanctions go up to R$ 50 million per infraction. Games, edtech, social and creator apps should check it before launch.
08Reputation platforms count as much as the law
Brazilian consumers check complaint platforms such as Reclame Aqui and consumidor.gov.br before buying, and companies that answer there are seen as more trustworthy. Clear terms, a Portuguese support channel and a cancellation flow that works reduce both complaints and legal risk, because the same issues that reach Procon usually appear first on these platforms.
