This Privacy Policy applies to Pairsleuth, the matching-pairs logic puzzle for iPhone published by Jafforge (“we”, “us”, “our”). It replaces our general apps policy for this app, because Pairsleuth collects considerably less than that policy allows for.

Summary

Pairsleuth collects nothing. Its only network connection is to Apple’s App Store, to handle the one optional purchase.

  • No account, no sign-in, no email address, no name.
  • No analytics, no advertising, no tracking, no third-party SDKs.
  • Your results, streaks and settings stay on your iPhone and are never transmitted anywhere.
  • The app requests no system permissions: no location, camera, microphone, photos, contacts or notifications.

What we collect

Nothing. We have no server, and Pairsleuth contains no networking code of its own, so there is no mechanism by which your data could reach us. The daily board is generated on your iPhone from the date; it is not downloaded.

What the app stores on your device

  • Your result on each daily board you play (whether you solved it, and how many wrong flips it took), and a daily board you have started but not finished
  • Your best result on each ladder tier, and the highest tier you have beaten
  • Your settings: sound, haptics, and whether you have seen the How to play round
  • Whether the optional purchase has been made

This data is written only to the app’s private storage on your iPhone. It is included in your normal iPhone backup (iCloud Backup, or an encrypted backup to a Mac) under Apple’s terms, the same as any other app’s data, and it is deleted when you delete the app.

The in-app purchase

Pairsleuth offers one optional, one-time purchase that adds the expert clue set and opens the ladder above tier 7. The purchase is handled entirely by Apple through StoreKit. Apple processes the payment and keeps the receipt under its own privacy policy; we receive no payment details and no identifying information about you. The app stores a single flag on your device recording that the purchase was made, and asks the App Store to confirm it when you restore.

Third parties

Apart from Apple’s App Store for the purchase above, there are none. Pairsleuth bundles no analytics, advertising, crash-reporting or attribution SDK, and makes no request to any other server, ours or anyone else’s.

Children

Pairsleuth is a logic puzzle made for adults and is not directed at children. Because it collects no personal information from anyone, it collects none from children.

Changes to this policy

If a future version of Pairsleuth adds a feature that changes any of the above, this policy will be updated before that version ships, and the change will be described in the app’s release notes.
