Privacy Policy for KenKen

Effective Date: May 15, 2026

1. Introduction

Welcome to KenKen, a logic puzzle game that combines arithmetic and critical thinking. This Privacy Policy explains how we handle data in our iOS application.

We are committed to protecting your privacy. This app is designed to work completely offline, meaning no data leaves your device.

2. Information We Do NOT Collect

We do not collect any of the following:

• Personal information (name, email, phone number, etc.)
• Usage data or analytics
• Location data
• Financial information
• Contacts or social media data
• Photos or camera access
• Microphone or audio data
• Health or fitness data
• Any data transmitted to third-party servers

3. Data Stored on Your Device

KenKen stores the following data locally on your device using iOS UserDefaults:

• Game Progress: Current puzzle state, selected cells, and notes
• Best Records: Completion times for each difficulty level
• Game Settings: User preferences such as difficulty selection

This data:

• Is stored only on your device
• Is never transmitted to any server
• Is automatically deleted when you delete the app
• Cannot be accessed by other apps

4. Third-Party Services

KenKen does not use any third-party services, SDKs, or analytics tools.

The app is built using:

• Swift and SwiftUI (Apple's native frameworks)
• No third-party dependencies
• No advertising networks
• No tracking frameworks

5. Data Security

Since all data is stored locally on your device using iOS UserDefaults, it benefits from Apple's built-in security features:

• Data is sandboxed to the KenKen app
• iOS encryption protects data at rest
• No network access means no data transmission risks

6. Data Deletion

All game data is automatically and permanently deleted when you:

• Delete the KenKen app from your device
• Reset your device

No data is stored on any server, so no additional deletion requests are necessary.

7. Children's Privacy

KenKen is suitable for users of all ages, including children. Since we do not collect any personal information, the app is compliant with the Children's Online Privacy Protection Act (COPPA).

Parents can be confident that their children's privacy is fully protected when using KenKen.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in a new version of the app with an updated effective date. We encourage you to review this policy periodically.
