How a thing gets collected
A thing joins your collection the moment you meet it: when you put it on either side of the comparer, open its page, or stand yourself next to it. Greyed tiles are the ones you have not met yet, and they still link to their pages, so you can go and find them.
The count is per kind as well as overall, so it is easy to see that you know every animal but only a few mountains. The sizes shown on the tiles are the published figures from each thing’s page.
Where the list is kept
The list is stored in this browser on this device, never on a server. There is no account to lose and nothing to export; the price is that clearing the browser’s site data empties the collection, and a second device starts from zero.
