## Frequently Asked Questions

### Does Jabble open the link automatically?

No. The QR code is decoded and the content is shown to you as plain text. Nothing opens automatically — you choose whether to visit the link.

### Is the QR code image uploaded to a server?

No. Decoding happens entirely in your browser using your device's processing power. Your image and camera feed never leave your device.

### What types of QR codes can this read?

Any standard QR code — URLs, plain text, WiFi credentials, contact cards (vCard), email, SMS and more. Jabble shows you the raw decoded content either way.

### How can I tell if a QR code is safe?

Always check the destination domain before opening a link. Be cautious of shortened URLs, addresses that use raw IP numbers, or domains that look like a misspelled version of a brand you trust.
