How Arca looks, speaks and counts.

Appearance

Settings → Appearance: Light, Dark or Same as your device (follows your device’s light or dark mode). On a computer, the theme button at the bottom of the sidebar switches too: each tap goes light → dark → system. The choice is per device.

Language

Settings → Language: English or Dutch (Nederlands).

Currency

Settings → Currency: Euro, US dollar or British pound. This only changes the symbol shown next to amounts; nothing is converted.

Financial month

Settings → Financial month sets the day your month starts, usually payday. Budgets, insights and Safe to spend all follow this period.

• Tap a day from 1 to 28 to set your start. It saves straight away, and the bar below shows where today sits in the period.
• Move the start to Friday when it falls on a weekend: for a salary that arrives before the weekend.
• Exceptions: when payday moves for just one month (holidays), add an override for that month only.

Paid on the 25th?

Set your start day to 25. Your “month” then runs from the 25th to the 24th, so this month’s salary pays for this month’s spending.

Budget and bills

Settings → Budget & bills decides what counts as spending.

Count recurring bills in category budgets

• Always: every bill counts toward its category’s budget.
• Only budgeted categories: bills count only where you’ve set a budget for that category.
• Never: budgets only track day-to-day spending; recurring bills are left out.

Shared costs: how split bills and money paid back show up in your reports.

• Show the full amount (the default): reports show what left your account.
• Show my share: reports show only your part of a shared cost. Your cash flow and the forecast always use the full amount.
