FAQ
Is my data uploaded to a server?
No. Whenever possible, processing happens locally in your browser and we do not store your inputs or results on our servers. (Network requests may still occur for page loads and ads.)
Static vs dynamic QR codes?
Static QR codes embed the data directly in the image. Dynamic QR codes redirect through an intermediate URL so content can be changed, but they require a managed backend.
