However, as I said in previous blogs, I still want people to be able to use Tiamat for free to an extent. So starting with the next update, people will be given 1 FREE export per month. Note, this free export doesn't carry over and doesn't entitle you to free tiles. But this essentially allows the casual user to use Tiamat for free once a month, assuming they are exporting an adventure scale map.
I still need some way to support Tiamat for free use, so at some point in the near future (but probably not in the next update), Tiamat will have some sort of ad integration. If you don't want to see ads, all you have to do is spend money. Ads will only show for users who haven't bought any additional exports or tiles.
