**QR Previewer** helps you check a QR destination before you open it. Instead of launching a website immediately, QR Previewer shows where the QR code leads first, so you can decide what to do next. **Features** * Preview the destination before opening * View a readable URL and domain details * Review local risk signals such as HTTP links, short links, IP-based hosts, and heavy tracking parameters * Get a cleaner link suggestion when removable tracking parameters are detected * Choose how to continue: open in Safari, use the in-app browser, or copy the link * Revisit your most recent scans on this device **Why use QR Previewer** QR menus, event links, and shared codes often open too quickly. QR Previewer adds a simple review step, making it easier to inspect unfamiliar destinations before visiting them. **Important** QR Previewer provides local heuristic guidance only. It does not guarantee safety and is not a malware scanner or phishing blocker. **Privacy** Scan results are processed on device in the current version. QR Previewer itself does not upload your scanned URLs or scan history.
