How does AI Repair work?
When you scan a damaged or torn barcode, our on-device AI analyzes the remaining visible bars and digits. It calculates the mathematically correct checksum (modulo-10 algorithm) to reconstruct the missing information instantly.
The scanner isn't detecting my barcode. Why?
Please ensure you are in a well-lit environment. Avoid glare on shiny labels. If the barcode is severely damaged, try using the "Manual Entry" mode by tapping the keyboard icon to verify the digits manually.
Is my data uploaded to the cloud?
No. UpCheck Pro works 100% offline. Your scan history and repaired data are stored locally on your device for your privacy and security.
