Hi Nora,

Thank you for contacting us. mSecure Cloud syncing is very secure, and we recommend all our customers use it. It is the most simple sync feature to use, and since your data is stored in the cloud, when you need to retrieve it, you simply sign in to the account in mSecure and the data syncs in. We do have an article on how your data is protected. If you are interested in reading it, here is the link to the article on our support site: https://support.msecure.com/en/support/solutions/articles/36000064305-msecure-s-security-model-secure-by-design
