Centsei is a private, offline-first expense tracker built for people who just want to know where their money goes — without handing their financial life to a cloud server. YOUR DATA STAYS YOURS • Everything is stored on your device. No sign-up, no login, no account required. • No ads. No trackers. We never see your numbers. • Optional cloud sync is end-to-end encrypted with a code only you hold — even we can't read it. FAST, HONEST MONEY TRACKING • Add an expense or income in seconds with clean, tappable categories. • Built for Malaysian Ringgit (RM) with proper formatting — amounts are always calculated to the exact cent. • Beautiful monthly reports: spending, income, balance, and a category breakdown at a glance. BUDGET & PLAN • Set a monthly budget and get a gentle nudge before you overspend — overall and per category. • Recurring expenses auto-fill each month, so rent and subscriptions are never forgotten. • A 6-month trend shows whether you're heading the right way. FIND ANYTHING • Search and filter your entries instantly. • Tap any category to drill into its line items. PRIVATE BY DESIGN • Lock the app with a PIN. • Works fully offline — open it on a plane, in the basement, anywhere. • Export your data anytime as JSON or CSV. It's your money; it's your data. BILINGUAL • Full Traditional Chinese and English — switch any time. Centsei is designed to be the calmest, most private money tracker on your phone. Open it, log it, get on with your day.
