Fast Budget - Expense Manager Security & Privacy Scorecard
Android
Financial transactions and budget data are stored in Firebase and optionally synced via Dropbox. Analytics and crash reporting through Firebase are disabled until the user explicitly consents, and ad networks (Google AdMob, Facebook Audience Network) are never activated for paying subscribers. Users who connect bank accounts do so through Salt Edge, a third-party financial data aggregation service.

1 issue identified across security and privacy analysis.
Top security issues
- Financial transaction data (balances, debts, credit cards, transactions) stored in unencrypted SQLite database — accessible on rooted or forensically examined devices
- HTTP deep link intent-filter for authentication and registration paths lacks domain verification (autoVerify=false), enabling auth flow disruption by malicious apps on same device
- WebView with JavaScript and DOM storage enabled POSTs credentials to developer-controlled domain — XSS on that domain could expose session data
Top privacy issues
- Google AdMob and Facebook Audience Network collect Google Advertising ID (GAID) for behavioral profiling in an app that holds users' complete financial history
- Complete financial history (every transaction, debt, credit card, budget) stored unencrypted on device, exposing sensitive data in rooted or forensic access scenarios
- Privacy Sandbox ad permissions (ACCESS_ADSERVICES_TOPICS, ACCESS_ADSERVICES_AD_ID, ACCESS_ADSERVICES_ATTRIBUTION) declared, enabling Topics API-based interest profiling

- Biometric authentication support lets you lock the app with fingerprint or face recognition
- The app locks automatically after 7 failed PIN attempts, with a 10-minute cooldown
- Firebase Analytics and crash reporting are disabled by default and only enabled after you explicitly consent
- Firebase App Check verifies the authenticity of the app before granting server access
- Cloud backup is disabled by default, keeping your financial data off external storage unless you choose to enable Dropbox backup
- Dropbox backup uses a secure authorization flow with no private keys or secrets stored in the app
- Ad networks are never activated for premium subscribers, so no advertising identifier is shared if you pay for the app
- Database queries are constructed safely throughout, protecting against data corruption from malformed input
Areas for Improvement
GDPR / CCPA Compliance
The app's privacy practices could be strengthened by:
Encrypting the Local Financial Database
Using an encrypted database for storing transaction history, credit card details, and debt records would protect your complete financial history on devices subjected to forensic examination or advanced physical access. This would bring the app in line with industry recommendations for sensitive financial data at rest.Tightening App Link Verification for Authentication Screens
Enabling domain ownership verification for the authentication and registration screen links would ensure only Fast Budget can respond to those links, preventing other apps on the same device from potentially interfering with the sign-in flow.
Security Enhancements
- Verified App Links for Sign-In
Activating verified handling for authentication-related app links would ensure that only Fast Budget opens those screens, adding an extra layer of protection against link interception by other installed apps.
