Privacy

Each of our apps with a website of its own has its own privacy policy there, and that is the one that applies to it: Pyxen, Qwartz, Reflow, Smudjo. This page covers our games without a website of their own, Chessdown and Flushline, and this website.

Our games

We collect nothing. The games have no accounts and no sign-up or login of ours. They contain no analytics, no advertising, no third-party SDKs, and no tracking of any kind. They make no network connections of their own, we operate no servers for them, and we receive no data from them.

Data stored on your device

Your progress — completed levels, daily streaks, best scores, achievements, purchase state, and settings such as sound and appearance — is stored on your device by the app. Some games also store recordings of your own games on the device so you can replay them. None of this is sent to us. There is no iCloud or cross-device sync, so this data stays on the device that created it, and deleting the app deletes it.

Game Center

Game Center is optional and is Apple's service, not ours. If you sign in, your leaderboard scores and achievements are handled by Apple under Apple's Privacy Policy. We never see your Apple Account. The games work fully signed out — declining Game Center only turns off leaderboards and achievements.

Purchases

Purchases are handled entirely by Apple through the App Store and StoreKit. We never see or store your payment details, and we receive nothing from a purchase beyond Apple's aggregated sales reports, which do not identify you.

Sharing

Where a game lets you share something — such as exporting a game replay — the file is created on your device and goes only where you send it through the iOS share sheet. It does not pass through us.

Diagnostics from Apple

If you have chosen in iOS Settings to share analytics and crash data with app developers, Apple may make crash and usage reports available to us. These come from Apple in aggregated, anonymised form and are not linked to you. You can turn this off at any time in Settings › Privacy & Security › Analytics & Improvements.

Children

Because the games collect no personal data from anyone, they collect none from children.
