Once a file is added to your Dropbox account, it's synced to our secure online servers. All files stored online by Dropbox are encrypted and kept on secure storage servers.
Where are the Dropbox servers located?
Storage servers are located in data centers across the United States. Additionally, storage servers are available in Australia, the European Union, Japan, and the United Kingdom for eligible Dropbox users.

Can I change where my file data is stored?
If your team’s data is stored in the United States but your team’s billing address is elsewhere, you may be able to migrate your data to a server closer to your team’s billing address.
