Privacy Policy

Last updated: January 2026

This Privacy Policy describes how Prototypic LLC ("we", "us", or "our") handles information when you use the Sudoku mobile application ("the App").

Overview

• The App does not collect personal data.
• The App does not use analytics or tracking.
• The App does not use third-party SDKs.
• The App does not show ads.
• All game data is stored locally on your device.

Information collection

The App does not collect, transmit, store, or process any personal or usage data. No accounts are required and no information is sent to any server.

Local data only

Game progress and settings are stored locally on your device using on-device storage. This data never leaves your device and is not shared with us or any third party.

Analytics and tracking

The App does not use analytics, tracking technologies, or telemetry of any kind. We do not track usage, behavior, or interactions.

Third-party services

The App does not integrate with any third-party services, SDKs, advertising networks, analytics providers, or cloud platforms.

Data sharing

Because no data is collected, no data is shared with third parties.

Children’s privacy

The App does not knowingly collect personal information from anyone, including children under the age of 13. Since no data is collected at all, there is no risk of child data collection.

Your choices

You can use the App fully without providing any personal information. You may delete all locally stored data at any time by removing the App from your device.

Changes to this policy

If this Privacy Policy changes, the updated version will be made available at this location with a revised "Last updated" date.
