Delicious LIbrary V2 "phones home" on start-up. It wants to connect to the company for some reason, presumably logging, but who knows: Transferring data about you, your system, your database, pass along files it looks at on your system, etc.

If the connection is prevented, the software doesn't work thereafter. So it appears not to be just a check for updates. They want to mandate/force the connection.

Inquiries to the company get only an automated response with the latest story about how tiny they are and how overwhelmed they are. In four years, I've gotten only 1 meaningful response to 6 inquiries (a refund for DL2 because of the privacy issue, as I reverted to DL1).

DL version 1 did not phone home and only connected to amazon for look-ups.

Database software that initiates connections to the manufacturer's site without (normal) user knowledge should be considered DOA. The potential for mischief is extremely high.
