Using Crypho, you communicate either directly with your contacts or in groups. To add a contact, you must invite them to be your contact and they must approve your contact request.
Your contacts are listed in your main Crypho home screen. Only you can see who your contacts are. They are not shared with others.
To add a contact, click the + button in the main contact listing screen. Enter their email address and a personal message. Crypho will send them an invitation email to be your contact.
If they don’t have an account already, they will get an opportunity to make one.
Once they accept your invitation, they will appear in your contacts list and you will appear as a contact in their list.
In the invitations section, you can see all invitations you have sent and received. The counter badge on the main invitations menu entry shows how many invitations you have received but not yet responded to. The menu has two entries:
Received invitations: A list of invitations received from others, each invitation with an option to accept or reject it. Rejecting an invitation throws it silently away without alerting the person that invited you.
Sent invitations: Shows a list of invitations that you have sent to others. You can withdraw an invitation by clicking the x next to it. This silently deletes the invitation, and does not send a notification to the recipient.
To delete a contact, click on them in the main list so you can view the conversation with them. Inside the conversation options menu in the top right corner of the chat, there is a Delete contact option. Clicking this will delete the person from your contacts, and you will be removed from their contact list as well.
When you delete a contact, all your conversation history with this contact is also deleted.
