Secure QR Share ứng dụng cho Android mô tả
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
- Sender enters text or a password and chooses a shared PIN.
- The app encrypts the payload with AES-256 and displays a QR code.
- 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
- Works fully offline — no internet permission required at runtime
- 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.
