Small, hand-built mobile puzzle games.

Knock

A quiet puzzle about consequences. Flick a piece, it hits the next, the chain does the rest. The game itself plays offline, and there is nothing to buy.

The daily and all-time leaderboards do use the network, and joining them is optional. Nothing is sent to the leaderboard until you tap “Join Leaderboard”; if you never do, the game still plays in full. When you join, the app is given an anonymous name — there is no sign-in, no email and no password — and you can leave, deleting it and every score attached to it, from Settings at any time. The privacy policy says exactly what is sent and how long it is kept.

We read everything sent here. If you are reporting a bug, the app's Settings → Send diagnostics produces a technical report you can attach — it contains no personal information, and nothing is sent anywhere until you choose to send it.
