Expense Ninja · Last updated September 22, 2026

Overview

Expense Ninja helps you track spending from receipts and manual entries. This policy explains what we collect, how we use it, and the choices you have.

Local storage

Expense, budget, category, and preference data is stored locally on your device by default. We do not upload your receipt images or expense ledger to our servers unless you opt into a cloud-backed account feature. When you convert currencies, the app may fetch public exchange rates; that does not include your payment card details.

Camera and photos

Camera and photo library access are used only to capture or pick receipts for on-device text recognition. Images stay on your device unless you choose to share them elsewhere.

Biometrics

Face Lock uses the system biometric APIs. Biometric templates never leave the secure hardware and are never sent to Expense Ninja.

Notifications

If you enable notifications, we may send local alerts about budgets, scans, insights, and billing. You can change or revoke permission anytime in system Settings and inside the app.

Account and authentication

When you sign in, authentication is handled by Firebase Auth (email, Google, or Apple on iOS). We store the account identifiers needed to keep you signed in on this device.

Analytics and crash reports

We use Firebase Analytics and Crashlytics to understand app usage and fix crashes. This may include app activity, device info, and crash logs linked to your account ID. Data is processed by Google on our behalf and is not sold or used for advertising.

Subscriptions and billing

Premium purchases are processed by Apple App Store or Google Play. We receive entitlement status (active, trial, cancelled) but never your full payment card details.

No sale of personal data

We do not sell your personal data. We do not share expense contents with advertisers.

Deleting your data

Use Personal Info → Delete my data to sign out, delete your Firebase account when available, and wipe expenses, budgets, categories, and preferences on this device. You can also clear app storage or uninstall.

Children

Expense Ninja is not directed at children under 13 (or the equivalent minimum age in your region). We do not knowingly collect data from children.
