This Privacy Policy describes how CalcPro ("the App", "we", "us") handles information when you use our mobile application. We are committed to protecting your privacy and being transparent about how the App works.
CalcPro does not collect or transmit:
The App makes one type of outbound network request: fetching live currency exchange rates from a public API (exchangerate-api.com). This request contains no user data — it simply asks for the latest exchange rates, which are the same for all users worldwide.
Fetched rates are cached locally on your device for up to 4 hours to minimise network usage. If no internet connection is available, the App falls back to built-in approximate rates.
The App stores the following data only on your device, never on any server:
This data is stored using Android's standard SharedPreferences mechanism and is never transmitted anywhere.
The App uses the following third-party service solely to retrieve exchange rates:
No advertising SDKs, analytics services, or tracking libraries are used.
CalcPro does not knowingly collect any information from anyone, including children under the age of 13. The App contains no features that require personal information.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date. We encourage you to review this page periodically.
