Sync happens automatically and seamlessly when you are signed in from any platform. Your data is stored locally and when your device connects to our cloud servers through sync, a copy of your local data is propagated to our servers. The transmission is secured using SSL Security and your data is stored on our servers using password and key protection. In case of conflict between two editions on the same item, the latest one will remain, allowing you to have the most updated information with you anywhere you go.
