Privacy Policy

Last updated: May 15, 2026

1. Introduction

Welcome to Nonograms ("we," "our," or "us"). We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we handle data when you use our Nonograms mobile application ("App").

2. Information We Do NOT Collect

We want to be transparent about what information we do not collect:

• No Personal Information: We do not collect names, email addresses, phone numbers, or any other personal identifiers.
• No Usage Data: We do not track how you use the app, your gameplay patterns, or time spent.
• No Location Data: We do not access or collect your geographical location.
• No Financial Information: The app contains no purchases, subscriptions, or payment processing.
• No Contacts or Social Data: We do not access your contacts, social media accounts, or friend lists.
• No Device Information: We do not collect device identifiers, IP addresses, or hardware specifications.

3. Data Stored on Your Device

The only data stored by Nonograms is saved locally on your device using iOS UserDefaults:

• Game Progress: Your current puzzle state (which cells you've filled or marked)
• Best Times: Your fastest completion times for each difficulty level
• Completion Count: Number of puzzles completed per difficulty

This data:

• Is stored exclusively on your device
• Is never transmitted to any server
• Cannot be accessed by us or any third party
• Is automatically deleted when you delete the app

4. Third-Party Services

Nonograms does not integrate with any third-party SDKs, analytics services, advertising networks, or data collection platforms.

The app is built using only Apple's native frameworks:

• SwiftUI (user interface)
• Foundation (data management)
• Combine (reactive programming)

There are no external network calls, no API connections, and no data sharing with any third parties.

5. Data Security

Since Nonograms does not collect or transmit any data, there is no risk of data breaches, unauthorized access, or data misuse. All game-related information remains exclusively on your device within Apple's secure sandbox environment.

6. Data Deletion

All locally stored game data (progress, best times, completion counts) is automatically and permanently deleted when you:

• Delete the Nonograms app from your device
• Reset your device to factory settings

No manual data deletion request is necessary, as we do not maintain any servers or databases containing user information.

7. Children's Privacy

Nonograms is suitable for users of all ages, including children under 13. The app:

• Does not collect any personal information from children
• Does not display third-party advertisements
• Does not contain in-app purchases
• Does not include social features or external communications
• Is fully functional offline without any network connectivity

We believe Nonograms provides a safe, educational, and entertaining experience for children without any privacy concerns.

8. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you by updating the "Last updated" date at the top of this policy. We encourage you to review this Privacy Policy periodically for any changes.

Any updates will maintain our commitment to zero data collection and complete offline functionality.
