@mashy, thanks for the great question! When a device is offline, any notes created or edited are saved locally on that device. As soon as the device connects to the internet, any local changes are immediately synchronized with our servers. This process happens automatically in the background. This updated data is then propagated to all other connected devices of the user, providing seamless synchronization. This way, you can create notes offline on one device and then access and continue working on another as soon as it connects to the network. Data security and privacy is our top priority, so all synchronization happens over an encrypted connection.
