History

No, not on our servers. Static QR codes are generated entirely in your browser: the content is encoded to an image locally and never needs to be uploaded to build it. What is kept is a copy of the finished image, in your own browser’s local storage on this device, so that the History page can hand you the same file again without re-rendering it. Nothing in that list has been anywhere else, it keeps up to 100 recent items, and you can clear it at any time from the History page.

History

Yes, from the History page. Your last 100 generated and scanned codes are saved in your browser, with favorites you can pin. Browser storage is limited, so once it fills up the oldest saved images are released first (favorites last) and those rows stay in the list without a download; nothing else is lost. History also lives only on that device and browser, so it will not follow you to another computer. Dynamic QR codes are different: they are stored with your account, and you can re-download them with their saved design from Dynamic QR Codes on any device.

History

Only on your own device. Scan results are added to the History page, which is stored in your browser’s local storage and never on our servers. History keeps up to 100 recent items; you can favorite entries to protect them, or clear everything at any time. Note that scanned content (including things like Wi-Fi passwords) sits in that local history until you clear it, so clear it on shared computers.

History

The generation process is private, because static codes are built in your browser without uploading content. But the finished QR code itself is not encrypted: anyone who can see and scan it can read everything in it. Never encode passwords, private keys or sensitive personal data in a code you will display publicly. For Wi-Fi codes, remember the network password is readable by anyone who scans.
