...No data leaves your device unless you explicitly want to share your models on local Wi-Fi. Say no to tracking and third parties that want to suck your data! Only for iPhones and iPads with FaceID or LiDAR. Don't move with the scanned object/scene, it absolutely needs to stay still during the whole time you're scanning. Move your iPhone/iPad slowly while scanning. If the scan quality isn't sufficient, try moving even slower, try playing with it to see how slow/fast movement influences quality (try also moving very slowly, e.g. at 5mm per second). Ensure that the scanned object is within the scanner range (depends on the selected Precision (0.5mm, 0.8mm)) all the time.
