This privacy policy describes the privacy practices of Ktarian, a single-player puzzle game developed and published by Matthew Drayton ("we", "us"), and distributed on the Apple App Store under the bundle identifier com.drayton.Ktarian.

 

The short version: Ktarian collects no personal information about you, sends nothing about you to anyone, and contains no advertising, analytics, or tracking of any kind. Everything below is the long version of that statement.

 

1. INFORMATION WE COLLECT

We collect no personal information from you. We do not ask for your name, email address, phone number, location, contacts, photos, microphone, camera, or any other identifying or device-level information. There is no account system and no sign-in flow inside the app.

 

2. DATA WE SEND OFF YOUR DEVICE

None. The app makes no network requests of any kind. It contacts no servers operated by us or by any third party. It does not transmit your gameplay, settings, preferences, device identifiers, IP address, crash logs, or any other information across the internet.

 

3. INFORMATION STORED ON YOUR DEVICE

The app saves a small JSON file at Application Support/ktarian_save.json inside its private sandbox on your device. That file contains:

• Your unlocked-level number, best level completion times, and total in-app play time
• Your current settings (joystick sensitivity, master volume, haptics on/off)
• A profile-creation timestamp
• The IDs of any in-game "Memory" stills you have unlocked

 

This file lives only on your device. It is not transmitted anywhere. You can erase it at any time by tapping CONFIGURATION → RESET PROGRESS inside the app, or by uninstalling the app.

 

4. ANALYTICS AND THIRD-PARTY SDKS

We use no analytics services, advertising networks, attribution services, crash reporting services, or third-party SDKs of any kind. The app is built using only Apple's standard first-party frameworks (SwiftUI, UIKit, SceneKit, AVFoundation, Core Haptics, Foundation).

 

5. ADVERTISING AND IN-APP PURCHASES

The app contains no advertising and no in-app purchases. We do not participate in any ad network, mediation platform, or attribution system.

 

6. PERMISSIONS

The app requests no system permissions at runtime. You will not see any "would like to access…" prompts.

 

7. CHILDREN

The app is rated 4+ and is suitable for all ages. Because we collect no information at all, we collect none from children. This policy complies with the U.S. Children's Online Privacy Protection Act (COPPA), the U.K. Age-Appropriate Design Code, and the EU GDPR's Article 8 by virtue of collecting nothing.

 

8. APPLE APP STORE

When you download or update Ktarian through the App Store, Apple may collect information about that transaction in line with Apple's own privacy practices. We do not control or have access to that information. See https://www.apple.com/legal/privacy for Apple's policy.

 

9. YOUR RIGHTS

Because we hold no information about you, there is nothing for you to request, correct, export, or delete from us. To erase the local save file on your device, use the in-app RESET PROGRESS button or remove the app.

 

10. CHANGES TO THIS POLICY

If we ever update this policy — for example because a future version of the app adds a feature that requires it — we will post the revised policy at the same URL and update the "Last updated" date at the top. Material changes will also be summarised in the App Store update notes for that version.
