Frequently asked questions

Yes. There's no paid tier, no usage limit, and no account required to scan or generate codes.

No. Everything happens locally in your browser. Camera frames, uploaded images, and generated codes are never uploaded or stored on a server — see the Privacy Policy for the full explanation.

Only to show a live preview so you can point at a code. Your browser handles the permission directly; Quiet Zone reads video frames locally to look for a code and never transmits them anywhere.

Camera access needs a secure connection (HTTPS) and browser permission. If it's blocked, check your browser's site settings for a denied camera permission, or use the "Upload image" option instead, which works from any photo of a code.

Low, Medium, Quartile, and High control how much of a generated code can be damaged, smudged, or obscured and still scan correctly. Higher levels are more forgiving but make the code visually denser. Medium is a good default for most uses; use High if the code will be printed small or somewhere it might get scratched, like a sticker.

QR codes can hold a few thousand characters, but longer text produces a denser, harder-to-scan code. For links and short messages you won't notice a limit; for long text, a higher error correction level or a shorter link works better.

Once the page has loaded, scanning and generating both run locally, so a spotty connection won't interrupt an in-progress scan. Loading the page itself still needs a connection the first time.

Quiet Zone shows you the decoded destination before it opens anything, so you can read the link first instead of being redirected automatically. That said, no scanner can tell you whether a destination itself is safe — treat an unfamiliar link the same way you would if someone texted it to you.
