Technologies are generally described for a data synchronization scheme. In some examples, a method performed under control of a client device may include connecting to a server based at least in part on user account login information; receiving, from the server, a data file stored in connection with the user account; storing the received data file in a local data storage; receiving a request to logout the client device; determining that the client device is disconnected from the server and/or that the data file stored on the local data storage is not synchronized with the data file stored in connection with the user account; and encrypting the data file stored on the local data storage. |
