How do I restore my Die Cast Shelf Pro purchase?

Open Settings in the app and tap Restore Purchases. Make sure you are signed in with the same Apple ID used for the original purchase.

Why is my barcode scan not finding a catalog match?

The offline catalog covers thousands of Hot Wheels mainline UPCs. Specialty lines, older cars, or non-Hot Wheels brands may not auto-fill — you can still add the item manually with the scanned UPC saved.

How do I back up my collection?

Go to Settings and export your collection as CSV or JSON. JSON backups can be restored with merge or replace options. Photos can be included or excluded from JSON backups.

Getting started

How do I add my first car?

Tap the + button on My Shelf. Enter details manually, pick from the offline catalog, or scan a barcode to auto-fill when a match exists.

What is Peg Hunt Mode?

Peg Hunt is an in-store duplicate checker (Pro). Scan a UPC and the app tells you immediately if you already own that car — no internet required.

How does the free tier work?

You can track up to 25 items for free. Upgrade once to Pro for unlimited items, Peg Hunt, Photo Match, Series Tracker, the widget, and more.

Troubleshooting

Barcode scanner won't open or shows a black screen

Allow Camera access in iOS Settings → Die Cast Shelf → Camera. Force-quit and reopen the app. If the issue persists, restart your device and ensure iOS is up to date.

Scan works but no catalog data appears

The catalog loads on first lookup. Not every UPC is in the offline database — specialty and older releases may need manual entry. The scanned UPC is still saved on the item.

iCloud sync isn't working

Enable iCloud sync in Settings, confirm you're signed into iCloud on the device, then restart the app as prompted. Sync uses your private iCloud account; we cannot access your data.

How do I restore Pro after reinstalling?

Open Settings → Restore Purchases while signed into the same Apple ID used for the original purchase.

How do I export or move my collection?

Settings → Export CSV or Export JSON Backup. JSON supports restore with merge or replace. Share the file to Files, email, or cloud storage you control.

Device requirements

Die Cast Shelf requires a recent version of iOS with camera access for barcode scanning and optional photo capture. iCloud sync requires an iCloud account.
