The information about the tracker seems to be quite outdated on marvelsnap.pro and marvelsnapzone

It still says there's no overlay, being the main thing. And I assume you obtain some data from the game's running memory now, because the overlay sees things way before the player can see them (like it knows if I won or lost as soon as the last turn starts to play out, or that a card was revealed before it flips, or that the latest area revealed created squirrels)

Yeah the website still says stuff like no Overlay and that trackers and such aren't legal. But we know that the tracker from Untapped does just the same.
