A. Local Data: If you use the free version, all trade logs and settings are stored natively on your device via SharedPreferences. We cannot read or transmit this data.
B. Pro Data: If you subscribe to TradeGuard Pro, we collect your Google Account email address (via Firebase Auth) and securely store your trade history in Google Firestore strictly for device synchronization.
Your email is used exclusively as an identity key to link your devices together. Your encrypted trade logs are used strictly to restore your active tracking constraints.
We use Firebase (Google) for database infrastructure and authentication. All payments are securely processed by an external Merchant of Record. TradeGuard never accesses your raw credit card numbers.
You have the right to request full deletion of your cloud data at any time. A manual "Wipe Data" button is located in the app drawer to permanently purge your local cache and sever your identity from the database.
