Finan+

Finan+ is a simple, lightweight and private personal finance app. It works fully offline: your data stays on your device, with no account and no external server.

Note: the app interface is in Brazilian Portuguese and amounts are in Brazilian reais (R$).

Features

• Quick entry for income and expenses: a large amount, category and date chips, and Undo after saving

• Accounts and credit cards: each card shows its open bill, limit usage and due date, with alerts when the limit is almost used

• Installments, recurring transactions, bills to pay and to receive

• Current balance and end-of-month forecast, calculated the same way on every screen, plus a calendar with each day's balance

• Each month's balance on its own or carried over from previous months, as you prefer

• Shared expenses: split a bill with friends or family (equally or by each person's amount), see who owes what, record partial payments, attach the receipt and send a PDF statement or a Finan+ image via WhatsApp

• Monthly limits per category and savings goals: saving into a goal takes the money out of the account without counting it as an expense, with an alert when a goal will miss its deadline

• Debts: loans and financing in installments, with the next installment and how much is left

• "What if…?" simulator to save, plan a purchase or pay off a debt early, without touching your data

• Read a bill or boleto: amount and due date from a PDF (password-protected too), the boleto line or a Pix code

• Reports with charts and PDF report export

• On-device assistant: suggests categories from descriptions, summarizes the month, gives saving tips and answers quick questions, always explaining why

• Balance widget and daily due-date reminders

• 7 themes, including Gruvbox, OLED, Tokyo Night and Nord, with an optional glass effect

• Network access (optional): use Finan+ in your computer's browser on the same Wi-Fi, with the data staying on the phone. HTTPS with the phone's own certificate, a code and confirmation on the phone

• JSON backup and restore (compatible with Finan+ web and Finan+ for Linux) and CSV export

• Automatic backup: one copy a day, encrypted with a password, to a folder you choose (phone, SD card, Google Drive, Nextcloud…)

Privacy and security

• Data encrypted with AES-256-GCM, key kept in the Android Keystore

• PIN and/or strong biometric lock, with auto-lock

• Screenshots blocked by default and an option to hide amounts

• Discreet notifications and widget when the app is protected

• No ads, no trackers, no account, no sign-up

• The network permission is only for local network access: off until you turn it on, works only on your home Wi-Fi and turns itself off after 10 minutes of inactivity. The app never connects to the internet
