Geek Communication encrypts and decrypts content in your browser, without a conventional account system. Online authorization retains necessary identity and delivery references and audit records. The site does not receive or store your content, whether plaintext or ciphertext, and does not hold all the material needed to decrypt it. Server records alone cannot decrypt or recover your content.
