We cannot recover your scan history. It is held by your browser on your device and never reaches us, so once you clear your browser data it is gone from the only place it existed. The same applies to a code you generated and did not save: nothing you create here is stored on our side, so there is no copy for us to look up.
This is a small operation, not a support desk. Most messages are answered within a few days. A clear description of the problem, and a screenshot where one helps, will always get a faster and more useful answer than a general report that something is broken.
Smart Scan AI builds free, browser-based QR and barcode tools, and the Smart Scan AI app on Google Play. The website is operated from outside Japan and is published in English and Japanese. Our Terms of Use and Privacy Policy set out the rest.
