Frequently asked questions
Where is my ledger data stored?
Ledgers, categories, transactions, notes, and settings are stored locally on your current device. MiniBook requires no account and does not automatically sync data to the cloud.
How do I back up and restore my data?
Open Settings → Data and backup, choose Create full backup, then use the system share sheet to save it to Files or another safe location. To restore, choose Restore from backup, review the displayed ledger and transaction counts, and confirm.
What is the difference between CSV export and full backup?
CSV is intended for viewing and analyzing transactions in a spreadsheet. A full JSON backup preserves ledgers, categories, transactions, and their relationships so MiniBook can restore them.
Does changing the display currency convert existing amounts?
No. The currency setting changes only the displayed symbol and unit. It does not perform exchange-rate conversion or modify saved amounts.
Can I recover data after deleting the app?
Uninstalling the app removes its local data. If you previously saved a full backup to Files or another location, you can restore that file after reinstalling.
What should I include in a bug report?
Please include what happened, steps to reproduce it, the MiniBook version, iPhone model, and iOS version. If you attach screenshots, remove real financial or other sensitive information.
