Privacy posture: No account, publisher server, analytics, advertising, tracking, or automatic upload. Inspection records and label photos stay on device unless the user explicitly exports a report.

Important: Checks selected GS1 data syntax and user-provided approved values only. It does not grade barcode print quality, replace an ISO-compliant verifier, or provide GS1, FDA, regulatory, or legal certification.
