02 FinVau Journal: features
The app records income and expenses with an interval, fixed costs with a debit day, budgets as separate pots, one-off expenses for the current month, and insurance policies with premium, policy number and term.
The monthly overview shows the four totals, the savings rate as a percentage of income, a ring chart of expenses by category, the remainder cascade and the remaining amount per day left in the month.
In addition there are lists for a savings goal and a loan, two calculators for monthly rate and affordability, notes with simple formatting, and export as CSV and PDF.
03 FinVau Journal: data processing
All data stays on the user device. There is no server, no user account and no synchronisation. The database is encrypted with AES-256 via SQLCipher; the key is held in the Android Keystore and, on devices with a security chip, in StrongBox.
The operating system backup and device transfer are switched off. Data leaves the device only when the user creates an encrypted backup or an export.
The only outbound traffic is an anonymous count of opened screens through an instance operated by the provider. It is off by default and requires consent. Amounts, labels and categories are never transmitted.
