No. AllerLens has no sign-up and no sign-in. Your allergen profile and scan history are stored on your device.
Open Profile → Clear scans and settings, or delete the app. Because we don't store your personal data in the cloud, either one removes everything. Reports sent with “Report a problem with this result” are anonymous, so we cannot link them back to you.
Open the dish, tap Report a problem with this result and pick a reason. This sends us a short anonymous report (the dish name, the tag the app showed, the reason you picked and the app version) so we can fix the mistake. It does not include your allergen profile or anything that identifies you, and we cannot reply to a report, so email us if you want an answer. AllerLens uses AI to read menus and it can make mistakes — always confirm ingredients and preparation with restaurant staff before you order, especially if your allergy is severe. AllerLens provides informational guidance and is not medical advice.
Scanning works best on printed menus in good light, with the whole menu in frame and the text roughly upright. If the camera can't focus, you can import a photo from your library instead.
Menus can be translated into English or Spanish. The source language is detected automatically.
