Privacy Policy

Effective date: May 19, 2026

Hearth Sudoku is designed as an offline puzzle game. We do not collect, sell, rent, or share personal data from the app.

Data Collection

The Hearth Sudoku iOS app does not require an account, does not use third-party advertising, does not use tracking identifiers, and does not send gameplay data to our servers.

Local Game Data

The app stores your current puzzle state locally on your device so that your game can resume after you close and reopen the app. This local save data stays inside the app's sandbox on your device.

Network Access

The app does not use network services for gameplay, analytics, advertising, or account sync.

Children's Privacy

Because the app does not collect personal data, we do not knowingly collect personal information from children.
