Did a QR code bring you here?
The code you scanned may hold a hidden secret. Your scanner can read only its public content: this link. To see the secret, scan the same code with QRench.
A QR code with a secret inside.
Plainly secret.
A QRench code is an ordinary QR code. Any scanner reads its public content — a link, a text or a contact — as usual. Only QRench finds the secret hidden inside the same QR code.
One QR code, two audiences
This is a form of steganography: hiding information in plain sight. Share or print a QRench code like any other QR code.
Public content
A link, a text or a contact. Every scanner reads it, and every phone can open it.
The secret
Only QRench finds it. Lock it with a password, and only the people you give the password to can read it.

What's built in
An everyday scanner
It reads every QR code and checks each one for a secret. Secret scan or Regular scan, with one tap; Regular scan reads barcodes too.
Scan from anywhere
From the camera, from your gallery, or share a picture from any app — a screenshot, a picture in a chat.
Business cards
Scan a contact QR code and tap a number to call. Add to contacts opens your phone's Contacts app with the details filled in — QRench never reads your contact list. Make your own in Create.
Share to QRench
Share a link, a text or a contact to QRench from any app, and make a QR code from it.
Lock a secret
Lock a secret with a password, with the key made on your phone. Without the password, nobody can read it.
Your QR codes, kept
The QR codes you make and the ones you scan, on your phone, with two samples to try at once. Save QR code images to your gallery, or share them.

Private by design
- Your QR codes, secrets, pictures, and the text and contacts you share to QRench are read on your phone and never leave it.
- No account, no ads, and no analytics of its own.
- To read QR codes and barcodes, QRench uses Google's ML Kit, which sends Google usage statistics about the scanner — never your QR codes or pictures.
- Android backup is off: your Library stays on your phone.
- Links open only when you tap them, and the whole link shows first.
The details are in the Privacy Policy.
A secret without a password is hidden, not private: anyone with QRench can read it. For anything personal, set a password and share it privately. If the password is lost, nobody can recover the secret. A damaged, small or poorly printed QR code may not give its secret.
Plainly secret.
Make and scan QR codes that hide a secret only QRench can read.
