At Safe Spend, we believe that your personal finance data is highly sensitive and should remain private. Our system is built to minimize the collection of personal telemetry and restrict data processing to secure server-side APIs that you control. We do not sell your personal financial data to third-party brokers.
All data input into Safe Spend is stored in Firebase Firestore under isolated user records. Client-side reads and writes to Firestore are completely locked down. All database reads/writes are performed strictly on the server-side via the Firebase Admin SDK to guarantee security.
When you use the AI Budget Coach or the Receipt OCR Scanner, select data (such as receipt images or transaction histories) is transmitted securely to Google's Gemini API endpoints. We use the Google AI developer APIs strictly for real-time inference. Your transaction inputs are not saved or used to train general foundation models.
We use secure, HttpOnly session cookies to authenticate your account and persist dashboard state. These cookies are cryptographically signature-validated on the server-side on every request. We also cache user theme selections locally on your device.
You retain complete control over your database records. You can clear your transactions, resetting all cash balances, goals, and recurring entries permanently at any time through the Settings console. Once deleted, this action cannot be undone.
