7. The server device of claim 4 , wherein the management application is configured to:

identify the currently active instance of the communication client application when a contact is added to the plurality of contacts; and

partition the contact into a respective contact grouping of the at least two different groupings that is associated with the currently active instance of the communication client application.

8. A method, comprising:

executing a management application on a hardware processor of a server device performing:

storing, in memory, sets of privacy settings associated with a user account at the server device, each set of privacy settings associated with a respective instance of a communication client application that enables communications over a packet-based network with other communication clients;

receiving an indication of a currently active instance of the communication client application;

identifying a current set of privacy settings associated with the currently active instance of the communication client application for the communications associated with the user account over the packet-based network;

retrieving the current set of privacy settings associated with the currently active instance of the communication client application; and

applying the current set of privacy settings associated with the currently active instance of the communication client application to the communications over the packet-based network.

9. The method of claim 8 , further comprising:

storing the sets of privacy settings in a look-up table.

10. The method of claim 9 , further comprising:

receiving a user identifier that identifies the user account;

receiving a token identifier that identifies the currently active instance of the communication client application; and

retrieving the current set of privacy settings associated with the currently active instance of the communication client application from the look-up table based, at least in part, on the user identifier and the token identifier.

11. The method of claim 8 , further comprising:

storing a list comprising a plurality of contacts associated with the user account; and

maintaining at least two different groupings of the plurality of contacts.

12. The method of claim 11 , further comprising:

maintaining respective contact privacy settings for each grouping of the at least two different groupings of the plurality of contacts.

13. The method of claim 12 , further comprising:

maintaining, for a first instance of the communication client application associated with the user account, a first set of the respective contact privacy settings;

maintaining, for a second instance of the communication client application associated with the user account, a second set of the respective contact privacy settings;

applying the first set of the respective contact privacy settings to the communications over the packet-based network when the first instance is the currently active instance; and

applying the second set of the respective contact privacy settings to communications over the packet-based network when the second instance is the currently active instance.

14. The method of claim 11 , further comprising:

identifying the currently active instance of the communication client application when a contact is added to the plurality of contacts; and

partitioning the contact into a respective contact grouping of the at least two different groupings that is associated with the currently active instance of the communication client application.

15. A client terminal device, comprising:

a memory configured to maintain a communication client application associated with a user account;

at least one hardware processor to implement a first instance of the communication client application and a second instance of the communication client application effective to enable communications associated with the user account over a packet-based network with other communication clients via a respective instance of the first instance or the second instance, each respective instance of the communication client application configured to:

send a set of privacy settings associated with the respective instance of the communication client application to a server device that configures the communications over the packet-based network with the other communication clients;

send, to the server device, a message indicating that the first instance of the communication client application or the second instance of the communication client application is the active instance associated with the user account;

retrieve, from the server device, the respective set of privacy settings associated with the active instance of the communication client application; and

apply the respective set of privacy settings to the active instance of the communication client application for the communications over the packet-based network.

16. The client terminal device of claim 15 , wherein:

the first instance of the communication client application comprises a web browser based instance of the communication client application; and

the second instance of the communication client application comprises a separate application from the web browser based instance.

17. The client terminal device of claim 15 , wherein the active instance of the communication client application is configured to send, in the message indicating the active instance, a user identifier associated with the user account and a token identifier associated with the active instance of the communication client application.

18. The client terminal device of claim 15 , wherein:

the memory is configured to:

maintain a first set of privacy settings associated with the first instance of the communication client application, including a privacy setting that allows the communications with an identified communication client;

maintain a second set of privacy settings associated with the second instance of the communication client application, including a different privacy setting that blocks the communications with the identified communication client; and

the client terminal device is further configured to block or allow the communications with the identified communication client based on the active instance of the communication client application.

19. The client terminal device of claim 15 , wherein:

the first instance of the communication client application is configured to send, to the server device, a new contact of at least one other communication client to add to a contact list; and

the second instance of the communication client application is configured to retrieve, from the server device, the contact list with the new contact.
