Privacy Policy for CheckChange

Last updated: May 2026

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.

1. Information We Do Not Collect

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.

2. Information Stored Locally on Your Device

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.

3. Internet Access and Exchange Rates

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.

4. Estimates Only

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.

5. No Affiliation

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.

6. Data Sharing

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.

7. Advertising and Payments

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.

8. Children

CheckChange is not directed to children. The app is intended for users who want to estimate currency conversion and card-related costs.

9. Changes to This Policy

This Privacy Policy may be updated from time to time. The updated version will be posted on this page.
