01
Scan the code
Point your camera at one QR code. GuarDog reads it without launching the destination.
QR protection from the VitaLink family
VitaLink GuarDog
Know before you go.
Check what is behind a QR code before you open it. GuarDog explains where it leads, what it wants to do, and the warning signs it finds.
A safer pause between scan and open
Three steps. You stay in control.
GuarDog never treats a QR code like an automatic command. It decodes first, checks links away from your phone, and waits for your decision.
02
See what it contains
Get a plain-English explanation for links, Wi-Fi logins, calls, messages, contacts, and more.
03
Approve or decline
Review the verdict and destination. Nothing opens unless you deliberately choose to continue.
Clear, useful verdicts
Not a wall of security jargon.
GuarDog tells you what it found and why it matters, then shows the real destination before you decide.
No threats detectedNo common warning signs were found in the completed checks.
Use cautionSomething deserves a closer look before you continue.
Threat detectedGuarDog found a serious warning sign and recommends that you stop.
More than website links
Understand the code before it acts.
A QR code can do far more than open a webpage. GuarDog identifies common formats and describes the intended action in ordinary language.
Website links
Shows the real destination, redirects, reputation result, and detected warning signs.
Network logins
Shows the network name and security type before exposing or copying a password.
Text messages
Explains who the message targets and previews the prepared message body.
Phone calls
Displays the number and warns about premium-rate or unusual destinations.
Contact cards
Lists the contact details and flags hidden links or suspicious impersonation.
Plain text and more
Displays readable content without assuming it should be launched or trusted.
Built around a simple promise
Your phone should not have to visit a link just to find out what it is.
- Web links are checked by an isolated service, away from your phone.
- Your scan history stays on your device unless you clear it or uninstall.
- Readable links are not placed in long-term analytics logs.
- Repeat scan results may be cached for up to three hours, then expire automatically.
- Google Play handles payment details; GuarDog never receives your card number.
Android launch in preparation
Put GuarDog between the QR code and the tap.
Start with 25 trial scans. Subscription options and localized pricing will be shown by Google Play when GuarDog launches.
