Open iOS Settings → Privacy & Security → Camera and make sure QR & Barcode Smart Scan is turned on. If it isn't listed, delete and reinstall the app so iOS re-prompts for permission.

Try improving lighting, holding the phone still, and moving closer or further so the code fills the viewfinder. Pinch to zoom for small codes. Glare or a damaged code can also block scanning — try scanning from a photo instead.

The free version lets you scan and generate QR codes with a lifetime cap on scan history (20 items) and QR generation (5 codes). Pro removes both caps. All scanning features, URL safety checks, food nutrition lookup, camera/torch/zoom, and CSV export work on both tiers.

Pro Monthly is $1.99 / month. Pro Yearly is $11.99 / year (about 50% off the monthly rate). Both come with a 7-day free trial for new subscribers. Prices may vary by region — the App Store shows your local price before you subscribe.

Open iOS Settings → your Apple ID → Subscriptions, tap QR & Barcode Smart Scan, and choose Cancel Subscription. If you cancel at least 24 hours before the trial ends, you will not be charged. Deleting the app does not cancel the subscription.

Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com, sign in with the Apple ID that made the purchase, and request a refund. We can't process refunds directly.

Open the app, go to Settings → Restore Purchases, and sign in with the same Apple ID that originally subscribed. If that doesn't work, quit the app, connect to Wi-Fi, and try again. Still stuck? Use the contact form above.

Only on your iPhone, in the app's private storage. We do not upload it to any server. If you delete the app, the history is gone.

Yes for scanning and history. The URL safety check and food nutrition lookup need an internet connection because they query external services.

No. We do not collect personal data, use analytics SDKs, or use advertising SDKs. See our Privacy Policy for details.

Force-quit the app (swipe up in the app switcher), then reopen. If it still crashes, restart your iPhone. If it still crashes, delete and reinstall — your Pro subscription will restore automatically after signing in.

Check that you have an internet connection. If you turned off "Safety check" in Settings, the safety check won't run.

Wait 30 seconds — Apple's receipt can take a moment. Then open Settings → Restore Purchases. If it still fails, send us a message with a screenshot of your Apple ID Subscriptions page using the contact form above.
