Include your device model, iOS version, app version, language and steps to reproduce the issue. You do not need to send a complete backup or children’s personal information.
Languages and search
Choose Korean, English, Japanese or Spanish from the top language menu. Search by name, symbol or place of use.
Backup and restore
Choose Settings → Save backup. On iOS, find the JSON file in Files → Browse → On My iPhone/iPad → World Currency Atlas. Choose Settings → Restore backup, select the file and confirm. Restore replaces current records, so back them up first. Copy backups outside the app folder before deleting the app. The app folder name follows the iOS device language.
Sharing and records
Share from a currency detail screen. Cancelling the share sheet does not change records. No login or automatic cross-device sync is provided; records stay on the device.
Corrections and ads
Tell us the currency name, question, language and correction. Designs are representative examples; dates may refer to origins, first notes or unit reforms. Live exchange rates are not provided. Include your network status when reporting an ad issue.
