LinkGuard: Secure QR Scanner

Green Robot Labs

About this app

LinkGuard is a privacy-first QR & barcode scanner designed to help you scan safely and stay in control.
Before opening any link, LinkGuard shows a Safe Preview so you can check where it leads. Your scan history is saved locally on your device and can be protected with biometric lock.
