Seems reasonably clear to me- starting with Giveaway of the Day, continuing with Giveaway of the day! You have XX hours XX minutes to download and install it. - then there's
Terms and conditions
Please note that the software you download and install during the Giveaway period comes with the following important limitations: 1) No free technical support; 2) No free upgrades to future versions; 3) Strictly personal usage.
and under the FAQ link:
Is GOTD a trial?
Every program we give away is not a trial. We provide you with full-functioning registered version of software titles.
There are two points you need to remember:
* you have to install AND activate/register the product according to instructions given in the readme.txt file attached to every GOTD package.
* it should be done while the giveaway offer for the software is still on (within 24 hours).
Still we do not provide you with the lifetime license in terms of the fact that our package can be used to install the program on giveaway date only. It means that you will not be able to re-install the program after PC crash or install the program on another PC after the giveaway day is over.
being selective in reading does not mean the terms weren't clear.
