Cryptomator creates an encrypted vault locally, then stores the encrypted files in a folder that can be synced by a cloud provider. It is useful when you want to keep using a mainstream drive without uploading readable file contents. Your cloud provider can still observe account activity, storage use, and some file metadata; keep the vault password and recovery material safe.
