AssinaJá
A Brazilian subscription and recurring-charge detector that reads your connected bank and credit-card accounts via Open Finance, explains each recurring CNPJ in plain Portuguese, and walks you through cancelling the ones you forgot about.
Brazilian consumers who have lost track of streaming, gym, SaaS, and app subscriptions auto-deducted from their cards
- Recurring-charge radar that scans Pluggy-connected accounts and groups transactions by CNPJ and frequency
- Plain-language merchant explainer that turns raw CNPJs into 'this is the streaming service you subscribed to in March'
- Step-by-step cancellation guides tuned to the most common Brazilian subscription providers
- Monthly 'money leaks' report showing annualized cost of every forgotten subscription
The trending cata-centavo repo (85 stars) proves Brazilian Open Finance tooling has real developer pull, and Brazil's Open Finance rollout is mature enough for consumer-grade apps on top.
Brazil's subscription economy is large and maturing; Mercado Pago, Apple/Google Pay, and consumer-protection blogs all publish recurring-charge guidance, showing active consumer pain around auto-deducted charges.Cobrança recorrente no cartão: entenda e evite surpresas ↗Brazil's Reshaping of the Latin American Subscription Economy ↗
Nubank — Brazil's dominant neobank (~90M users) — launched an in-app 'Minhas Assinaturas' Subscription Manager in Dec 2025 covering streaming, gyms, health, gaming, education directly from the card; this is the free incumbent feature in the exact same vertical.Nubank lança Gerenciador de Assinaturas para auxiliar no controle de cobranças recorrentes ↗Nubank lança gerenciador de assinaturas para controlar pagamentos recorrentes ↗
Nubank ships the core feature free to a massive installed base; standalone subscription managers priced like Truebill ($7.99/mo in adjacent markets) will struggle against a no-cost incumbent, and a %-of-savings cut model is hard to enforce in Brazil.Subscription Tracker App — Find Every Recurring Charge ↗Nubank lança gerenciador que centraliza todas as assinaturas no app ↗

Open Finance data-sharing APIs (phase 4 covering credit-card transactions) are live, and cata-centavo's traction proves developer interest, but consumer-grade apps still need ITP/IPP certification, consent UX, and Open Finance Brasil participant agreements — meaningful compliance overhead.Relatórios - Open Finance Brasil ↗
