Data controller: Konrad Tompór, konrad4a@gmail.com. This policy applies to the Android app ProfitTrack (Google Play: Investment Portfolio Tracker, app.profittrack.android).
Transactions, portfolios, price alerts and settings you enter are stored only on your device. We have no servers and do not collect, upload or sell this data. Backups you export are files you control.
To show current prices the app requests public market data from third-party services (CoinLore, Binance, Gold API, Frankfurter, Yahoo Finance). These requests contain only the symbols being looked up, never your holdings or amounts. These providers may see your IP address, as with any internet request.
The free version shows ads served by Google AdMob. AdMob may collect device identifiers (such as the advertising ID), IP address and usage data to show and measure ads, and – where you have given consent – to personalise them. See how Google uses data from apps that use its services. Users in the EEA, UK and Switzerland see a consent form (Google User Messaging Platform) before the first ad and can change their choice anytime in Settings → Ad privacy. You can reset or delete your advertising ID in your device settings.
Premium is bought through Google Play Billing. Payment details are handled by Google; we only receive confirmation of the purchase.
Notifications are used only for price alerts you set up. The optional app lock uses your device's biometric or screen-lock check; fingerprint or face data never leaves the system and is not accessible to the app.
The app is not directed at children under 13.
We may update this policy; the date above shows the latest version. Questions: konrad4a@gmail.com
