Checkmate Challenge privacy policy

Last updated · OGStudio

In short: Checkmate Challenge collects no personal data. There is no account, no analytics, no advertising and no tracking. Your progress stays on your Mac, and the free trial and the unlock are handled by Apple through the App Store.

Who we are

Checkmate Challenge ("the Game") is a chess puzzle game for the Mac by OGStudio ("we", "us"), helloogstudio.com. This policy explains what the Game does with information when you play it from the Mac App Store.

What we collect

Nothing. The Game doesn't ask for your name, email address, location or any other personal information, and it sends nothing about you or how you play to us or to anyone else. On the App Store its privacy label is Data Not Collected.

  • No account and no sign-in of any kind.
  • No analytics: we don't measure how you play.
  • No advertising and no rewarded videos in the Mac version.
  • No tracking across apps or websites, and no advertising identifier.
  • No third-party SDKs: the Game contains no code from ad, analytics or social networks.

What stays on your Mac

  • Your progress and settings: levels, stars, coins, XP and rank, your Daily Challenge streak, the boards and avatars you’ve unlocked, and your music, sound and board view settings. These are saved in the Game’s own storage on your Mac and are never uploaded.
  • Trial timing: when the free trial started and the last time the Game was open, saved in your Mac’s Keychain. These are two timestamps and contain nothing about you. The Keychain keeps them if the Game is deleted and reinstalled, so the 24-hour trial can’t be restarted.

What goes over the internet

The puzzles, the 3D board and the chess engine are all built into the Game, so it plays fully offline. The only connection it makes is to Apple’s App Store, through Apple’s StoreKit, to:

  • show the price of the unlock,
  • start the free 24-hour trial and buy the one-time Lifetime Unlock when you choose to, and
  • check which of these you own, including when you use Restore Purchases.

Apple tells the Game which items your Apple Account owns, and the Game verifies this on your Mac. We don’t receive your Apple Account, name, email address or payment details.

Purchases

The free trial and the $9.99 Lifetime Unlock are processed by Apple. Apple gives developers sales reports that don’t identify you. Coins are earned by playing and can’t be bought with money. Apple’s privacy policy covers App Store transactions.

Crash reports

If you’ve chosen in macOS to share analytics with app developers, Apple may send us anonymous crash reports and usage statistics for the Game. Apple controls this, and you can turn it off in System Settings › Privacy & Security › Analytics & Improvements. We use these reports only to fix bugs.

Links

The Game doesn’t browse the web. Any web or email link opens in your own browser or mail app, and websites you visit have their own privacy policies.

Children

The Game is rated 4+ and is suitable for children. It collects no personal information from anyone, including children. It has no chat, no ads and no links to social networks. Buying the unlock always goes through Apple’s own purchase sheet, where parental controls such as Ask to Buy apply.

Removing your data

Since we hold no data about you, there’s nothing to delete on our side. On your Mac:

  • To reset your progress and settings, quit the Game, delete it, and delete the folder ~/Library/Containers/com.ogstudio.checkmatechallenge.
  • To remove the trial timestamps, open Keychain Access and delete the items named com.ogstudio.checkmatechallenge. The App Store also keeps its own record of your trial and purchase, so this won’t restart the trial or remove the unlock.

Your rights

Wherever you live, including in the EU, the UK and California, you have the right to ask what personal data we hold about you and to have it corrected or deleted. For Checkmate Challenge the answer is that we hold none, but you’re welcome to ask. We don’t sell or share personal information.

Changes

If the Game ever starts to handle information differently, we’ll update this page and its date before that version is released.
