Link Steam once and every game you own arrives with its hours played. Sort the pile into Playing, Completed, Backlog, Dropped, and Wishlist. Free, forever.

One click through the official Steam login. No password ever touches Tsumi.
Preview every matched game with its hours, untick anything you do not want, and confirm.
Everything lands in your library. Mark what you are playing, what is done, and what you are honestly never going to touch.
