CheckChange is a currency, fee and cost estimation app. It helps users estimate card payments, cash withdrawal costs, discounts, currency conversions and general unit conversions.
CheckChange does not ask for, collect, store or transmit your credit card number, CVV, bank login details, password, bank account number, ID number or any information that can be used to make a payment.
The app may store your selected card issuer, card type, billing currency, optional bank selection, optional foreign currency wallet settings, fee settings, selected currencies and saved calculations. This information is stored locally on your device and is used only to calculate estimated costs inside the app.
CheckChange uses internet access to download exchange rates from a third-party exchange-rate provider. The app does not send your credit card number, CVV, bank login details, password or bank account number to the exchange-rate provider.
CheckChange provides estimates only. Actual charges may differ depending on your card issuer, bank, billing date, exchange rate, card plan, fees, wallet settings and official tariff. CheckChange does not provide financial advice, banking services, payment services, loans, investment services or credit services.
CheckChange is an independent app and is not an official app of any bank, credit card company or financial institution. Company names may be used only to help users select relevant calculation settings.
CheckChange does not sell your personal data. Based on the current version of the app, the app does not share your locally saved calculation settings with third parties.
The current version of CheckChange does not include ads and does not include in-app purchases. If ads, subscriptions or paid features are added in the future, this Privacy Policy and the app’s Google Play declarations will be updated accordingly.
CheckChange is not directed to children. The app is intended for users who want to estimate currency conversion and card-related costs.
This Privacy Policy may be updated from time to time. The updated version will be posted on this page.
