The useful starting point
An account book becomes useful when entries can be checked and recovered.
Start with the right information
Define income, expenses, dates and categories. Enter a few familiar transactions and compare the displayed balance with a calculation you know.
Put it into practice
Decide whether the records belong to one browser or need shared storage. Test a reload and a second authorized session to understand the chosen scope.
Check before you share
Export regularly and keep the original transaction evidence. Correct an entry deliberately and confirm that the resulting totals change as expected.
