Support
CardMaster is an independent, local-first credit-card reward tracking app. Here is how to get help quickly and safely.
Before Contacting Support
- Confirm that you are running the latest App Store or TestFlight build.
- For incorrect reward or benefit terms, include the card name, the displayed source link, and the text that appears incorrect.
- For layout or card-art issues, include your iPhone model, iOS version, app language, appearance setting, and a screenshot.
- For content-update errors, include the displayed package version and the exact error message.
- Do not send full card numbers, security codes, passwords, bank statements, or other sensitive banking information.
- Do not clear local data or reinstall the app when asking for help with data recovery.
Data Recovery Boundary
Wallet and progress records are stored locally on the device by default. If you enable Live Sync, selected data is stored in your private iCloud account; the developer cannot access or reconstruct it. You can also export and import portable backup files manually. Normal Apple device or computer backups may be available depending on your settings.
Product Boundary
CardMaster is not affiliated with any bank or card network. It does not connect to bank accounts, process payments, automatically verify purchases, or provide financial advice. Eligibility and current terms should always be confirmed with the linked official source.
Contact
When you write in, do not include full card numbers, security codes, passwords, or bank statements.
