# Are my transfers to cloud accounts encrypted in transit?

For Google Drive, Dropbox, Amazon S3, typical S3-compatible services and SFTP, yes — the connection between your Mac and the service is encrypted. Plain **FTP** is the exception: it isn't encrypted, which is why Storage Studio warns you before you add an FTP account.

A self-hosted bucket storage server is encrypted only if its endpoint uses `https://`. Once your files arrive, how they're stored is up to the provider; check their own documentation for storage-side encryption options.
