Syne has a robust built-in memory system, so in the absence of a connection to the Syne app on a supported device, Syne will be able to store data internally for over 24 hours. The next time the Syne device connects to the app the data will be uploaded to your phone and then to the cloud. Alternatively, if you'd like access to immediate data, simply provide a supported device with the Syne app installed with your child to bring with them. You could also ask a supervising adult to download the Syne app on their device (but they will then have access to all of your Syne devices and data).
