Neowin warns image file mounting program Daemon Tools keeps track of what you mount and run using a service called MountSpace. A site named Within Windows discovered that Daemon Tools hashes every image you mount and sends it to MountSpace servers, even if you disable this feature during the installation of Daemon Tools.
MountSpace is a service that keeps track of the software that people are mounting and running in Daemon Tools. It does this by keeping track of every image you mount, along with information regarding the specific .iso file you used; it even knows if you're a first time user. By sending all of this information home, MountSpace ends up with your IP address, your history and who knows what else.
Daemon Tools offers you the option of disallowing MountSpace from using your mount statistics at installation, but this doesn't actually stop it from collecting them. As the privacy setting itself says, you're not telling it to stop collecting the information; you're just telling it to not 'allow Mountspace to use [your] mount statistics.' Ideally, these files are deleted immediately, but who knows?
