When it comes to financial applications like Centi PRO - Currency Converter, account and fund security is of utmost importance. This app ensures that your data remains private and secure through various means. Although the app does not handle real funds directly, the security measures in place guarantee that any personal information used for currency conversion is protected against unauthorized access.

Centi PRO employs optimal battery use by only downloading data when you use the app and not running background services. This approach minimizes potential security vulnerabilities associated with constant data exchange. Additionally, the app is ready to work offline, storing the last updated exchange rates locally on your device, which further reduces risks related to online data breaches.

The app also allows users to personalize their settings, adding an extra layer of security. For instance, setting Wi-Fi only data download can prevent unwanted access over less secure networks. With features such as turning currency symbols on or off and choosing the number of decimals to display, users have control over how their financial information is presented and accessed.

These rates are cached locally when you have an internet connection, allowing you to perform conversions even without internet access later on.

Moreover, the app offers additional functionalities that enhance the overall transaction experience. Users can view historical currency charts for any two currencies, copy calculation results, and create custom currencies with specific details like price, name, country, flag, symbol, and code.
