Inspects QR and barcode payloads before action, showing punycode, domain spelling, redirects, Wi-Fi details, calendar data, contact cards, and tracking parameters. Built for a focused job instead of a recurring subscription, QRveil includes: - Live Inspector - Payload Breakdown - Domain Safety - Saved Reports Everything works locally with no account, no ads, no analytics, no tracking, and no developer-operated backend. Your work stays on your device until you explicitly export or share it. One purchase includes every version 1.0 feature. There are no in-app purchases or locked tiers. The app explains payload risks but cannot guarantee that a destination is safe.
