Stats
The game records how much time has passed before a puzzle is solved and how many failures were made. This data stays on your device — nothing is collected automatically. If you solve a bunch of puzzles I'd love it if you sent your stats over: I use them to sort the puzzles by difficulty, and that helps a lot.
The Stats page is reachable from the main menu, under the Progress section. At the top, a selector lets you switch between the current collection and all collections. The Share button (or Open on desktop) exports the stats to send them over, and the Import button lets you re-inject a previously exported stats file.
Thank you very much.
