My Budget — Privacy Policy
My Budget works completely offline. It has no internet permission: nothing you enter ever leaves your phone through the app, and we (Khunt's Lab) receive no data from it.
What the app stores, and where
| Data | Where it stays |
|---|---|
| Entries, categories, budgets, fixed costs, incomes, goals, notes | A database inside the app on your phone |
| Receipt photos, and the words read from them | App-private storage on your phone. The text is read on the phone by Google's ML Kit library, which runs offline in the app — the photo is not uploaded anywhere. |
| Settings, reminders, app lock choice | App settings on your phone |
Backups you control
- Backup files you create (optionally encrypted with your passphrase) are saved where you choose — a folder, a cloud drive app, email. That service's own privacy terms then apply.
- Android's own backup: if Google backup is turned on for your phone, Android may include the app's data in your Google account's device backup, encrypted by Google, so it comes back on a new phone. You can turn this off in your phone's settings.
Permissions
- Camera / photos — only when you take or pick a receipt photo.
- Notifications — reminders, budget alerts and the month-end summary, if you turn them on.
- Run at start-up — to re-schedule your reminders after the phone restarts.
- Biometrics — if you turn on the app lock, Android's own fingerprint/face/PIN screen is used. The app never sees or stores biometric data.
- Bluetooth, nearby devices, location — only for "Sync with a phone nearby", see below.
No tracking
No analytics, no advertising, no accounts, no data sale. Nothing is shared with third parties.
Sync between your phones (optional)
If you turn on sync, My Budget moves your data between your own phones, never through a server of ours. There are two ways: phone to phone nearby (Bluetooth and Wi-Fi, through Google Play services' Nearby Connections, on the phones), or a sync file you pick in your own cloud storage. Everything that leaves a phone is sealed with the pairing code your phones share (AES-256-GCM encryption), so the cloud service and anyone nearby see only scrambled data. The pairing code stays on your phones and is left out of backups. What a phone announces nearby is not personal: a one-way group name and a random device ID. For nearby sync, Android asks for Bluetooth, nearby-devices and (on older Android versions) location permission, only when you tap "Sync with a phone nearby", because Android requires them to find devices; the app never reads your location.
Problem reports and email
If the app crashes, a report (the error and your phone model, no personal content) is kept on your phone. It is only sent if you choose to send it — by email, from your own email app. If you write to us, we use your email only to answer you and delete it when the matter is closed, unless the law requires us to keep it.
Children
My Budget is not directed at children under 13.
Changes
If the app starts to collect or send anything new — for example when optional purchases are added — this page is updated first, and the date below changes. Material changes are also mentioned in the app's release notes.
Your rights
Under the GDPR you may ask what data about you we hold, have it corrected or deleted, restrict or object to its use, and receive it in a portable form. Because these apps keep your data on your phone and we receive none of it, you can exercise most of these rights yourself: view, edit, export or delete the data in the app, or uninstall the app, which deletes it. For anything else, write to support@khuntslab.net. You may also complain to a data protection supervisory authority, for example the one where you live.
