Introduction

RBB Group ("we", "our", or "us") operates the Nano Chess mobile application (the "App"). This Privacy Policy explains how we handle information when you use our App.

Information Collection and Use

Information We Do Not Collect

Nano Chess is designed with your privacy in mind. We do not collect, store, or transmit any personal information or user data to external servers. Specifically, we do not collect:

• Personal identification information (name, email address, phone number)
• Device information or identifiers
• Location data
• Usage analytics or statistics
• Game progress or statistics
• Any other personal or sensitive information

Local Data Storage

All game data, including your progress, preferences, and statistics, is stored locally on your device using the following methods:

• SwiftData for game state and user profiles
• UserDefaults for application preferences
• Local file storage for game rules and configurations

This data never leaves your device and is not accessible to us or any third parties.

Third-Party Services

Nano Chess does not integrate with any third-party services, analytics platforms, or advertising networks. The App functions entirely offline and does not require an internet connection.

Children's Privacy

Nano Chess is suitable for users of all ages. We do not knowingly collect any personal information from children or any other users. The App does not contain any features that would allow data collection or communication with external parties.

Since all data is stored locally on your device, you can delete all App data at any time by:

• Deleting the App from your device
• Using iOS Settings to clear App data
• Reinstalling the App

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. Continued use of the App after any changes constitutes acceptance of the updated Privacy Policy.

Your Rights

Since we do not collect any personal data, there is no data for us to access, modify, or delete. You have complete control over all data stored by the App on your device.
