Secure QR Share

Secure QR Share lets you send passwords, PINs, and sensitive text to someone nearby without typing, screenshots, or cloud services — just a QR code.

HOW IT WORKS

1. Sender enters text or a password and chooses a shared PIN.

2. The app encrypts the payload with AES-256 and displays a QR code.

3. Receiver scans the code with Secure QR Share, enters the same PIN, and the original text is instantly decrypted and copied to the clipboard.

FEATURES

• AES-256-CBC encryption with PIN-derived keys — no server, no cloud

• Share sheet integration — highlight text anywhere and share directly into the app

• App Links support — QR codes can be opened from the camera or browser

• Optional unencrypted mode for non-sensitive public links

• No ads, no tracking, no analytics, no accounts

PRIVACY

Secure QR Share never transmits your data. Everything is processed locally on your device. The encryption key is derived from your PIN and never stored or sent anywhere.
