Overview
CardWin is a billing-cycle utility that helps users track credit card statement closing dates and payment due dates so they can estimate longer grace periods.
Privacy is a core product principle. In short: CardWin does not collect, store, or transmit personal data to the developer or to third parties.
What the app uses
The app only uses information that you manually enter, such as card names, statement closing dates, due dates, and optional notes.
CardWin does not collect or store credit card numbers, CVVs, bank account details, login credentials, or other sensitive financial information.
Where data is stored
Your entries are stored locally on your device using Apple's SwiftData framework.
If you enable iCloud sync, your data syncs through your own iCloud account across your personal devices.
The developer does not operate a backend service for this app and cannot retrieve or inspect your stored data.
Third-party services and network access
CardWin does not use advertising SDKs, analytics tools, social integrations, or third-party crash tracking services.
Core functionality works offline. When iCloud sync is enabled, any network activity is handled through Apple's platform services.
Children's privacy
CardWin does not knowingly collect personal information from anyone, including children under 13.
