Numo Budget privacy policy
Last updated: 14 November 2026
Numo Budget is an offline expense tracker and budget app for Android, developed and published by Novixway LLC ("Novixway", "we", "us"). This policy explains what Numo Budget does with information on your phone.
The short version: Numo Budget has no accounts, no ads, no analytics and no crash reporting, and it does not connect to any bank. Everything you enter stays on your phone. Numo Budget does not send your financial data, or anything else, to Novixway or to anyone else. A file only leaves your phone when you choose to export or back it up somewhere yourself.
Data kept on your phone
| Data | Why | Leaves the phone? |
|---|---|---|
| Accounts you create: name, currency, exchange rate you typed, opening balance, icon and color | to show balances and convert totals | No |
| Transactions you enter: amount, date, category, account, note | to show your history, budget and charts | No |
| Categories, monthly budget and category limits | to organize spending and track your budget | No |
| Subscriptions and repeating payments: name, amount, schedule, reminder setting | to add them on their dates and remind you before a renewal | No |
| Settings, such as your main currency, the day your budget month starts and app lock on or off | to keep the app the way you set it | No |
| Whether you bought Numo Budget Pro (a yes or no flag) | so Pro keeps working offline | No |
All of this is stored in Numo Budget's private app storage, which other apps cannot read. You can edit or delete any entry in the app at any time. Uninstalling Numo Budget, or clearing its storage in Android Settings, deletes all of it.
No cloud backup. Numo Budget opts out of Android's automatic cloud backup and device transfer, so your financial data is not copied to Google Drive by the system. To move or keep your data, use the app's own encrypted backup described below.
Exports and backups you make
- CSV export (Pro). Writes a spreadsheet of your transactions to a location you pick with the Android file picker (the Storage Access Framework). What happens to that file afterwards is up to you and the place you saved it.
- Encrypted backup (Pro) and restore. Writes all your Numo Budget data to a file you pick, encrypted with AES-256-GCM using a key derived from a password you choose (PBKDF2). The password is never stored and never leaves the phone; without it the file cannot be read, by you or by us. Restoring reads a backup file you pick and replaces the data on the phone.
Numo Budget holds no storage permission. It can read or write only the files you pick in the system picker.
Notifications
If you turn on a renewal reminder for a subscription, Numo Budget asks for permission to show notifications and shows one the day before that subscription renews. Reminders are created on the phone; nothing is sent to a server.
App lock
If you turn on app lock (Pro), Numo Budget asks Android to confirm it is you with your fingerprint, face or screen lock. Android handles this check. Numo Budget never receives or stores your biometric data or your screen lock.
Purchases (Google Play)
Numo Budget Pro is a one time in-app purchase handled by Google Play Billing. When you open the Pro screen or buy, the Google Play app on your phone talks to Google to show the price, process the payment and confirm your purchase. Novixway does not receive your payment details. Google processes purchases under the Google Privacy Policy and the Google Play Terms of Service. Play may tell us about the purchase in the Play Console (for example an order number, country and price) as it does for any app sold on Google Play.
Network
Numo Budget itself does not go online. It has no servers, does not download exchange rates, and does not connect to any bank or financial service. The only network activity related to Numo Budget is Google Play's handling of the Pro purchase and the normal app installs and updates handled by Google Play.
What we do not do
- No account or sign in, and no bank connection.
- No ads and no advertising ID.
- No analytics, tracking or crash reporting SDKs, and no Firebase.
- No sale or transfer of your information to anyone.
Not a financial service
Numo Budget is a personal budgeting tool. It does not provide banking, lending, investment, payment or any other financial service, and it does not give financial advice.
Children
Numo Budget is a general purpose app and is not directed at children under 13.
Changes
If this policy changes, the new version will be posted at this address with a new "Last updated" date. Material changes will also be noted in the app's release notes.
