Question 1

How are opening and closing balances calculated?

Accepted Answer

Automatically. The opening balance of any day is the running total of all earlier entries; the closing balance adds that day's cash in and subtracts cash out.

Question 2

Is my cash data private?

Accepted Answer

Yes — everything stays in your browser on your device. No signup, no cloud. Export the full book as CSV any time.

Question 3

Can I use it for previous days?

Accepted Answer

Yes — pick any date when adding an entry and when viewing. Balances recalculate across the whole book.
