This add-on sends the following data:

- .torrent files, with user configured values (such as labels).
- login information required to connect to the remote servers.

The data is sent only to the user-configured servers.
Absolutely no data is sent to Xirvik or any 3rd party service for any reason.
The add-on does however connect to Xirvik from time to time to fetch news and promotion information. These connections do not send any information about the user, his/her add-on usage or any kind of activity. They are plain http requests with no parameters.
