Couchdrop’s support team may access your file metadata (not file data) and logs for support purposes only.
Couchdrop’s engineering staff have access to the underlying technology that can access metadata and log information and the storage locations of the actual data. The encryption keys required to decrypt the actual data are stored in a key-management escrow service operated by Doppler.
It is possible within the product to block Couchdrop employees access within the application. It is a check box under Administration -> Security.
Note, if you do require support, Couchdrop may request you enable this or join them for a screen sharing session.
