Is my camera feed uploaded anywhere?

No. The video stream stays on your device: frames are decoded locally in your browser by JavaScript. Nothing is recorded, stored or uploaded — the scanner works entirely client-side.

Why does the scanner ask for camera permission?

Reading a QR code with your camera requires access to the video stream. The browser asks for your approval first and shows it in the address bar; you can revoke it at any time and nothing is ever sent over the network.

The QR code contains a link — is it safe to open?

Not always. Scanning shows you the raw destination before you click, which is exactly why reading QR codes on desktop first is safer than tapping blind links. Check the URL carefully — look-alike domains are a common phishing trick.

Can I decode a QR code from an image instead of the camera?

Yes — drop a screenshot or photo of the code into the image decoder below and it is read locally with the same privacy rule. PNG, JPEG, WebP and GIF all work, as long as the code is sharp and fully visible.
