  • Painting on captured images
    Painting on captured images
    Captured images can be highlighted with paint and immediately attached and sent. This facilitates review and other exchanges.
  • Encrypted file transfer function

    Internet Virtual Private Network is used between locations in some cases, but we suggest using it for file transfers, especially those involving highly sensitive data.
    There are often cases where a password is applied when sending an e-mail and the password is sent later, but this is quite inconvenient and it is unnatural to send the password by e-mail.
    This encrypted file transfer function is unique in that it uses public key cryptography and does not transmit any common key (password in the case of e-mail) over the network. Users will not experience any inconvenience despite the strong encryption.
  • Automatic backup function

    Back up various Chat&Messenger data. There are two methods for backing up: automatic backup and one-time manual backup.
    To avoid data loss due to human error, file corruption, disk failure, forced software termination, etc.
    We recommend that business users back up their various data.
