Privacy Policy — TradeCalc
Last updated: March 12, 2026
TradeCalc ("the App") is developed by Alex Masure.
1. Data Collection
TradeCalc does not collect, store, or transmit any personal data. All calculations are performed locally on your device. No account creation is required.
2. Advertising
The free version of TradeCalc displays banner advertisements powered by Google AdMob. AdMob may collect device information and advertising identifiers to serve relevant ads. You can opt out of personalized advertising through your device settings or by declining the App Tracking Transparency prompt.

3. In-App Purchases
TradeCalc offers a one-time in-app purchase ("TradeCalc Pro") that unlocks multi-asset support (futures, crypto, stocks), an iOS widget, and removes advertisements. Payment is processed entirely by Apple through the App Store. We do not have access to your payment information.
4. Exchange Rates
The App fetches exchange rates from a remote server for calculation purposes only. No user data, personal information, or device identifiers are sent with these requests.
5. Local Data Storage
User preferences (favorites, settings, calculation history) are stored locally on your device using Apple's SwiftData framework. This data is never transmitted to external servers.
6. Third-Party Services
7. Children's Privacy
TradeCalc is not directed at children under 13. We do not knowingly collect personal information from children.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected in the "Last updated" date above.
