Check camera permission, the Android camera privacy switch and other apps using the camera. Use good lighting, clean the lens and keep the full code visible. If the problem persists, reopen scanning and report the app version, device model and reproduction steps.

Detection freezes the view and marks codes with solid green circles. A single code opens after a short freeze; with multiple codes, tap a circle to choose and return to the frozen view to select another. Tap Scan again to resume the camera. Continuous mode also freezes and marks codes to collect a batch.

Core scanning, gallery recognition, QR creation and local history work offline. Product or book lookup, external websites, ads and analytics use a network connection.

Information comes from Open Food Facts or Google Books and coverage is incomplete. You can continue with a barcode search. This version does not compare live retailer prices or guarantee coupon validity.

There is no account or cloud synchronization. After app data is cleared or the app is uninstalled, the developer cannot restore local records. Export important records first and store the files securely.

Usage analytics is on by default; the current version has no in-app switch. Previously saved disabled choices are retained. Advertising privacy choices are available when required. The scan screen does not show banner ads or post-scan interstitials.
