No. Scans are analyzed by our cloud service, so you need an internet connection to create a new scan. Your saved library is available offline.

Subscriptions are managed through your Apple ID. Open Settings → [your name] → Subscriptions on your iPhone, then select How To Use and choose Cancel Subscription.

Retake the photo with the product's label or logo more visible, or add a short note about what it is before submitting. You can redo a scan from the scan detail screen.

Every scan is stored locally on your device. Delete individual scans from your library, or remove all data by uninstalling the app.

We read every message. Email support@howtouseapp.com with a short description and, if possible, a screenshot.
