1. What CashTrace Does
CashTrace is a personal finance app that reads SMS messages from your bank and credit card providers to automatically track your spending. All data is stored privately in your own account and is never sold or shared with third parties for advertising or analytics purposes.
2. Data We Collect
SMS Messages
CashTrace reads SMS messages on your device to identify bank and payment notifications. The text of SMS messages that contain financial transactions is stored in your private cloud account (Google Firebase Firestore) for the purpose of backup and preventing duplicate imports across devices. SMS messages that do not contain financial transactions are read briefly in memory and immediately discarded — they are never stored.
Transaction Data
From each relevant SMS, CashTrace extracts and stores:
- Transaction amount and currency
- Transaction type (debit or credit)
- Merchant or payee name
- Category and sub-category
- Date and time
Account Information
Your Google account name and email address, used only for sign-in via Google Authentication.
Custom Rules
Any merchant extraction or categorization rules you create within the app.
3. How Your Data Is Stored
By default, all data is stored locally on your device only. No data is sent
to any server unless you explicitly sign in with Google.
If you choose to sign in, your data is synced to Google Firebase Firestore
under your unique user account for backup and multi-device access. Only you
can access your data. Nishant Sharma (the developer) does not access
individual user data.
You can use CashTrace fully without signing in — your transactions, rules,
and settings remain entirely on your device in that case.
Firebase is operated by Google LLC. See Google's Privacy Policy at
https://policies.google.com/privacy for how Google handles infrastructure data.
4. Advertising
CashTrace displays ads provided by Google AdMob. AdMob may collect device identifiers and usage data to serve relevant ads. You can opt out of personalized ads in your device settings under Google → Ads → Opt out of Ads Personalization.
See Google AdMob's Privacy Policy at https://support.google.com/admob/answer/6128543 for details.
5. Data Sharing
We do not sell, trade, or share your personal data with any third party except:
- Google Firebase — for authentication and cloud storage (your own private data)
- Google AdMob — for displaying ads (device-level ad identifiers only)
6. Data Retention and Deletion
Your cloud data is retained until you choose to delete it. To delete all your data:
1. Open CashTrace → tap your profile picture → Delete Cloud Data
2. Uninstall the app to remove all locally stored data
This permanently removes all your transactions, rules, and settings from Firebase.
7. Children's Privacy
CashTrace is not directed at children under 13. We do not knowingly collect data from children.
8. Changes to This Policy
If we make significant changes to this policy, we will update the "Last updated" date above. Continued use of the app after changes constitutes acceptance.
