We typically respond within 2–3 business days.
Where is my expense data stored?
Expenses, budgets, categories, and preferences stay on your device by default. Receipt images are not uploaded to our servers.
How do I lock the app?
Turn on Face Lock in settings. Expense Ninja uses your phone’s built-in face or fingerprint unlock. That unlock data stays on your device and is never sent to us.
How do currency conversions work?
The app fetches public exchange rates from jsDelivr and currency-api.pages.dev. Those requests include your device’s IP address and the currency code — not your expenses or payment card details.
How do Premium purchases work?
Premium is handled by Apple App Store or Google Play. We only receive entitlement status (active, trial, cancelled), never your full payment card details. Manage or cancel subscriptions in your Apple ID or Google Play account settings.
Can I turn off notifications?
Yes. Change or revoke notification permission anytime in system Settings and inside the app.
Delete your data
In Account, use Download my data for a ZIP with spreadsheets and a PDF summary, or Delete my data to sign out, remove your account when possible, and clear expenses, budgets, categories, and settings on this device. You can also clear app storage or uninstall Expense Ninja.
