Found this on the WinPatrol site regarding WinPrivacy in case anyone is on the fence about this offer:
"If you purchase a license now, you will NOT have to pay any annual subscription fees, EVER! Anticipated annual subscription fees for purchases made after this sales ends will be $12/yr. Again, if you purchase now, you will NOT have to pay any subscription fees EVER!."
So evidently WinPrivacy is anticipated to be a subscription-driven product...unless one buys now.
