This information is stored on the client computer of the sender. In addition, this information is used in e-mail notifications so the to all recipients of a transfer know who the transfer comes from and how they can get in touch.
This information is only stored on client-side and not on server-side.

  • have to re-enter
it every time he initiates a new Cryptshare Transfer.Furthermore the e-mail address, as the basis in an e-mail based communication needs to be stored on server side for logging purposes and as a technical pre-requisite
  • this information with every use of the system.
  • Sender contact details are provided to the recipient to inform them where the information comes from and how to contact the sender.
  • Both sender and recipient log data are stored on the server for audit trail as well as for troubleshooting purposes.
  • Recipient e-mail addresses are held in a database to provide senders a comfortable way to select from a list of previously used addresses when sending a transfer.

Name and Phone Number

Web User Interface

Name and phone number of a sender are stored in Browser Cookies. These cookies are deleted automatically depending on what was configured by the administrator. By default Cryptshare Cookies will be removed after 30 days.

Besides from the automatic deletion of a browser cookie, the user can delete these cookies manually at any time by either using the built-in function for deleting cookies in the browser, or by using the deletion function in the Cryptshare User Interface:

Recipient e-mail addresses are stored in a server-side database. A maximum of HOW MANY addresses is stored per sender. When the sender enters an addition address, the oldest address from the list is deleted (first in first out). Recipient e-mail addresses can be deleted from the database using the web user interface.

Other Products

All other Cryptshare products store personal information in a local configuration file on client-side. When this file is deleted or the product is uninstalled this information is deleted as well.

Server-Side Logging

E-Mail/IP Addresses

E-Mail addresses and IP addresses are stored as meta-information together with other logging information concerning a Cryptshare Transfer. The retention period for transfer-log data depends on administrative settings.

Selective deletion of specific e-mail addresses is not possible as this information is part of the transfer meta-information.
