Issue a wash code
Issuing a code permanently marks it issued in this browser's records. It does not verify redemption at the wash.
History
Backup & restore
Export your records after issuing codes. Keep the backup somewhere private, such as iCloud Drive. Restoring replaces the current records.
Important: This app stores issue history only on this device/browser. Clearing website data, switching devices, or reinstalling without restoring a backup can lose tracking. The QR images are not access-controlled by this app. For private use, deploy to a password-protected HTTPS site; do not publish the code folder publicly.
