What happens to what you type
Nothing leaves your browser. Links, WiFi passwords, phone numbers, contact details — all of it is turned into a QR code by JavaScript running on your own device, and the resulting image is drawn locally. No request is made to any server with your content in it, because the site has no server to send it to.
You do not have to take our word for it. Open your browser’s network tab and type into the generator: you will see no requests. Or load the page, disconnect from the internet, and keep generating codes — it works fine offline. And the whole site is open source: the code is on GitHub.
Accounts, cookies and storage
There are no accounts, so there is nothing to sign up for and no profile to delete. The site sets no cookies. It does not write your input to local storage, so nothing you typed is left behind on a shared computer once the tab is closed — including the URL bar, unless you deliberately used a prefilled link.
Prefilled links like /wifi?ssid=Cafe&password=hunter2 are a convenience for embedding the tool, and the values are visible to anyone who can see that link or your browser history. That is a property of links in general, but it is worth saying out loud on a page about WiFi passwords.
Hosting
The site is served as static files by Cloudflare Pages. Like any host, Cloudflare handles the network request needed to deliver those files to you and may keep short-lived infrastructure logs — typically IP address, timestamp and the file requested — for security and abuse prevention. That is standard for any website you visit, we do not read those logs, and none of it contains what you typed into the generator.
Scanning
Scanning a code you made here does not contact this site. The data is inside the code, so a scan is a purely local operation between a camera and a pattern. We cannot count your scans, and neither can anyone else who is not sitting on the destination.
Analytics
There is no analytics on this site at all. No page-view counter, no third-party scripts, nothing. If that ever changes it will be Cloudflare Web Analytics — cookieless and aggregate — and this page will say so before it is switched on.
