Common questions
Where is my data stored?
Only on your iPhone, in Custodian's own storage, which iOS encrypts while your phone is locked. Custodian never goes online, so nothing is uploaded anywhere.
Does Custodian sync between devices?
Not yet. Your data stays on one iPhone. To move to a new phone, use a backup.
What if I get a new phone, or lose mine?
Make a backup first: Settings → Import, Export & Reset → Back up, then save the file to Files or AirDrop it. On the new phone, open the same screen and tap Restore from a backup. Restoring replaces everything on that phone.
Your iPhone's own iCloud or computer backup includes Custodian's data too, depending on your iOS settings.
If there's no backup, we can't get your data back, because we never have a copy.
How do I get my data into a spreadsheet?
Settings → Import, Export & Reset → Export CSV. The file opens in Excel, Numbers or Google Sheets. It includes your transactions, not your budgets.
Does changing my currency convert my amounts?
No. Settings → Currency changes only the symbol shown. Your amounts stay exactly as you entered them.
Can I log spending with Siri?
Yes. Say “Quick log in Custodian”, “Log an expense in Custodian” or “Log income in Custodian”. It saves to your default account unless you pick another one. If App Lock is on, unlock the app first.
Can Custodian connect to my bank?
No. Custodian never connects to your bank. To log faster, use Siri, the Quick Log widget, or a schedule for bills that repeat. Your bank's texts can also log purchases for you: see Settings → Bank texts.
How do I delete everything?
Settings → Import, Export & Reset → Reset data → Reset everything. It erases all your entries, receipt photos and reminders, and it can't be undone. If App Lock is on, it asks for Face ID or your passcode first. Deleting the app also deletes everything.
