Information We Collect
This Privacy Policy describes how VAYLONEX LABS ("we", "us", or "our") handles information in connection with the Monetra Android application — an offline expense tracker, budget planner, and money manager.
We distinguish between two types of information: local data that you create and control entirely on your device, and anonymous diagnostic data automatically collected by third-party SDKs to keep the app stable and performant.
Stays on Your Device
All financial records, budgets, categories, and notes are stored locally only — never transmitted.
Anonymous Diagnostics Only
Only crash reports and anonymous app-stability signals reach third-party SDKs — never your finances.
Zero Data Selling
We do not sell, rent, trade, or monetise your data in any form whatsoever.
100% Local Data Storage
Every piece of financial information you enter into Monetra is stored exclusively on your Android device using the device's internal storage (Room database). This includes, but is not limited to:
- Financial transactions — all income entries, expense logs, and transfer records
- Budget plans & goals — custom category budgets and savings targets
- Multiple account books — wallet, bank account, and custom account configurations
- Category names & custom labels — your personalised spending and income categories
- Transaction notes & attachments — any personal descriptions or memos you add
- App preferences & settings — currency selection, theme, and display configurations
Zero cloud exposure: None of this data is ever uploaded to, stored on, or transmitted through any remote server — including VAYLONEX LABS' own servers. We have no mechanism to access your financial data.
App Security Features
Monetra offers on-device security features to protect your financial data from unauthorised local access. These features are implemented with strict privacy controls and zero data exfiltration.
4-Digit PIN Lock
Your PIN is stored as a salted cryptographic hash on-device. The raw PIN is never stored. VAYLONEX LABS cannot view, retrieve, or reset your PIN.
Biometric Authentication
Fingerprint/face unlock is handled entirely by the Android OS (BiometricPrompt API). Monetra never accesses, processes, or stores your biometric data.
Biometric data (fingerprints, facial geometry) is managed by your device's Trusted Execution Environment (TEE). Monetra only receives a pass/fail authentication result from Android — never the biometric data itself.
Local Backup & Encryption
Monetra provides an optional local backup feature that exports your data to an encrypted file stored on your device or a location you choose. Here's exactly how it works:
- AES-256 Encryption: Backup files are encrypted using industry-standard AES-256 encryption before they are written to storage.
- User-Defined Password: The encryption key is derived solely from your chosen password. Only you possess this key — we never receive or store it.
- Zero Developer Access: VAYLONEX LABS does not have access to your backup files, your encryption password, or any decryption key.
- No Recovery Option: If you forget your backup password, we cannot recover your data. Please keep your password in a secure place.
Important: Backup files you upload to cloud services (Google Drive, Dropbox, etc.) are subject to those services' own privacy policies. Monetra only creates the encrypted file — where you store it is entirely your choice and responsibility.
Third-Party Services & Analytics
Monetra integrates certain Google Firebase SDKs to maintain app quality and stability. These services operate on anonymous, non-financial diagnostic data only. Your personal financial records are never shared with any third-party service.
| Service | Purpose | Data Type | Classification |
|---|---|---|---|
| Firebase Crashlytics | Crash reporting and app stability diagnostics | Anonymous crash stack traces, device model, OS version | Anonymous |
| Firebase Analytics | Aggregate app usage patterns (screen views, feature usage frequency) | Anonymous usage events — no financial amounts or category names | Anonymous |
| Firebase In-App Messaging | Displaying app update notices or feature tips to users | Anonymous installation ID for message targeting | Functional |
| Device & Network IDs | Processed ephemerally by Google Firebase SDKs for crash reports and fraud prevention | Approximate location (country/region), advertising ID (if available) | Ephemeral |
Strict data boundary: Firebase services never receive your financial amounts, transaction descriptions, custom category names, account names, or any data you enter into Monetra. We do not sell, rent, or trade any data to third parties.
For details on how Google processes this anonymous data, see the Google Privacy Policy and Firebase Privacy & Security documentation.
Data We Do Not Collect
To be fully transparent, the following categories of data are never collected, accessed, or transmitted by Monetra or VAYLONEX LABS:
- Your financial amounts, income figures, expense totals, or account balances
- Your transaction notes, merchant names, or personal descriptions
- Your category names, account book titles, or budget goal labels
- Your real name, email address, phone number, or any personally identifiable information
- Your precise GPS location — no location permission is requested by Monetra
- Your contacts, microphone, or camera — none of these permissions are used
- Your bank account numbers, card details, or any payment credentials
Children's Privacy
Monetra is a financial management tool intended for users aged 13 years and older. We do not knowingly collect any personal information from children under the age of 13.
Because Monetra does not collect personal identifying information from any user, the privacy risks to children are inherently minimal. All data remains on-device under the user's control. If you believe a child under 13 is using the app, parental supervision is advised. Uninstalling the app permanently removes all locally stored data from the device.
Your Rights & Data Ownership
You retain complete and exclusive ownership of all financial data you create in Monetra. As the data never leaves your device without your explicit action, you have full control at all times.
- Right to Access: All your data is immediately accessible within the app at any time.
- Right to Export: Use the in-app backup feature to export your data in an encrypted file at any time.
- Right to Delete: Delete individual records within the app, or clear all data by uninstalling the application.
- Right to Portability: Your encrypted backup file can be restored to any Android device running Monetra.
- Right to Opt-Out of Analytics: Disable analytics via your device's Privacy Settings or by resetting the advertising ID in Android Settings → Privacy → Ads.
Data Deletion
Deleting your data from Monetra is straightforward because everything is stored locally on your device:
- Uninstall the App: Uninstalling Monetra permanently removes all financial records, settings, and app data from your device.
- Clear App Data: Navigate to Android Settings → Apps → Monetra → Storage → Clear Data to wipe all local app data without uninstalling.
- In-App Deletion: Delete individual transactions, categories, or account books directly within the app at any time.
- External Backup Files: Any backup files saved to external locations (local storage or cloud) must be deleted separately by you from those locations.
Since VAYLONEX LABS never receives your personal financial data, there is no "remote deletion request" process needed. All your data resides entirely under your own control at all times.
Policy Updates
We may update this Privacy Policy from time to time to reflect changes in the app's features, legal requirements, or third-party services. When we do:
- The "Last Updated" date at the top of this page will be revised to reflect the new effective date.
- For significant changes, we will notify users via an in-app message or notification where technically feasible.
- Continued use of Monetra after any policy update constitutes your acceptance of the revised policy.
- We encourage you to review this page periodically. The latest version is always accessible via the link in Monetra's Settings screen.
