Envelope budgeting without an account — your data stays on your device
App: Envelopes: My Budget (Android) Developer: Ivanov Oleg Contact: support@envelopesbudget.org Effective date: 13 August 2026
The app has no server of its own. Your financial data is stored on your device and, if you choose to enable it, in your own cloud storage. The developer does not receive, store or process this data and has no technical means of seeing it.
The app contains no advertising, uses no analytics, and shares no data with third parties for marketing.
Everything you enter yourself: accounts, transactions, amounts, categories, payees, notes, scheduled payments, goals and — if you wish — photos of receipts. This information is kept in a database on your device.
The app does not request or collect your name, address, phone number, contacts, list of installed apps, advertising identifiers or location data.
On your device. The primary storage is a database in the app’s protected area. Uninstalling the app removes this data with it.
In your cloud — only if you connect it yourself. The app can synchronise your budget and store backups in one of these services: Google Drive, Dropbox or a WebDAV server. Data travels directly between your device and your own account in that service. The developer is not part of this chain and has no access to the files.
For Google Drive the app uses restricted access (drive.file): it can only
see the files it created itself and cannot browse the rest of your drive. In
Dropbox the app works inside its own folder and has no access to other files.
Over your local network. There is a mode for transferring data directly between two of your own devices over Wi-Fi. The data goes directly, bypassing the internet and any servers, and is encrypted with a one-time confirmation code that you enter manually.
Backups that go to the cloud can be encrypted with a password you set (AES-GCM, key derived via PBKDF2). The password is kept only on your device in the Android secure storage and is never transmitted. If you forget this password, the encrypted backup cannot be recovered — neither by you nor by the developer.
Wi-Fi transfers between devices are encrypted as well; the key is derived from the six-digit confirmation code, and the code itself is never sent over the network.
| Permission | Purpose |
|---|---|
| Internet | synchronisation with the cloud storage you connected |
| Camera | photos of receipts and QR code scanning |
| Microphone | voice entry of a transaction (recognition is done by Android) |
| File access | saving and reading backups, import and export |
| Biometrics | unlocking the app with a fingerprint or face |
| Notifications | reminders about scheduled payments |
| Local network | direct transfer between your own devices over Wi-Fi |
The app does not request location permission.
Voice entry uses the Android system speech recognition service. The spoken phrase is processed by the operating system and is subject to the privacy policy of that system’s provider.
The app contacts only the services you connect yourself:
None of these services receive data from the developer — only from you and at your initiative.
If paid features appear in the app, payments will be processed through Google Play. Payment details are handled by Google and are not passed to the developer. The developer receives from Google Play only the purchase status needed to grant access.
The app is not directed to children under 13 and does not knowingly collect data from them.
The data is yours and stays under your control:
There is no need to send a deletion request to the developer: the developer does not hold your data.
The app keeps a technical log of synchronisation events and errors. The log is stored on the device only, is never sent anywhere automatically, and is visible to you in settings. If you decide to send it to help resolve an issue, that happens solely through your explicit action.
The current version of this document is always available at https://envelopesbudget.org/privacy-en/. If the policy changes materially, the effective date will be updated.
