FinTrack Privacy Policy
Last updated: July 30, 2026
1. Introduction
FinTrack ("we", "our", "us") is a personal expense tracking application published by Cyfur. This Privacy Policy explains how we handle information when you use the FinTrack mobile application ("the App").
2. Information we collect
2.1 Data stored on your device
FinTrack stores the following data locally on your device unless you choose to export it:
- Transaction descriptions, amounts, dates, and types (income or expense)
- Custom categories and app preferences
- Biometric unlock preference (enabled or disabled)
- Backup files you create manually
We do not upload your transaction data to our servers by default.
2.2 On-device AI (optional)
The AI Savings Coach builds a local index of your spending habits on your device (retrieval-augmented generation). When Apple Intelligence (iOS) or Gemini Nano (Android) is available, advice is generated on-device. If the on-device model is unavailable, FinTrack shows rule-based tips computed from the same local data. Financial details used for coaching are not sent to Cyfur servers or to cloud AI APIs operated by us.
2.3 Data sent to third-party services
To keep the App reliable and up to date, we use Google Firebase:
- Crashlytics: anonymous crash reports (device model, OS version, app version, stack traces). Your transaction details are not intentionally included.
- Remote Config: fetches app settings such as minimum supported version, update messages, ad settings, and legal document text. No personal financial data is sent.
2.4 Advertising (Android)
On Android, FinTrack may show ads through Google AdMob. Google may collect and use your device's advertising identifier (Advertising ID), IP address, device information, and ad interaction data to deliver, measure, and improve ads. We do not share your transaction data with advertisers. Ad display may be controlled remotely via Firebase Remote Config. Learn more about how Google uses data: https://policies.google.com/privacy. You can manage ad personalization at https://adssettings.google.com/.
2.5 Support communications
If you email hello@cyfur.in, we receive the information you include in your message (such as your email address and message content) solely to respond to your request.
3. How we use information
We use collected information to:
- Provide core app functionality on your device
- Generate private savings tips from local spending context (on-device AI or rules)
- Diagnose and fix crashes
- Deliver app updates and legal notices
- Display and measure ads on Android (via Google AdMob)
- Respond to support requests
We do not sell your personal information.
4. Permissions
- Biometric authentication: to lock the App (optional)
- Storage / files: to export and restore backup files
- Internet: for Crashlytics, Remote Config, AdMob, and support links
5. Data retention and deletion
Transaction data remains on your device until you delete it or uninstall the App. You can erase all data at any time from Settings → Erase all Data. Crash reports are retained by Google Firebase according to Google's policies.
6. Security
We recommend enabling biometric unlock and keeping your device OS up to date. You are responsible for securing exported backup files.
7. Children's privacy
FinTrack is not directed to children under 13. We do not knowingly collect information from children.
8. International users
Your data is primarily stored on your device. Firebase services may process technical data on servers operated by Google in various regions.
9. Changes to this policy
We may update this Privacy Policy. Updated text may be delivered through the App via Firebase Remote Config. Continued use after changes constitutes acceptance.
