Between every HTTPS transfer of your data, from our end to yours (and back), every file you drag into the client is encrypted using the same powerful 256-bit AES algorithm.
Your files are de-identified so that they can't be traced back to you. We don't see your login or password even when you drop a file in. Neither does anyone else, for that matter.
Our Secure Regenerating Key Algorithm (SRK) means you don't have to manage any decryption keys — and that these keys are never transmitted with your data.
