Overview

"Sudoku Reasoning" (the "App") is an offline classic 9×9 Sudoku practice tool focused on the reasoning process, developed and operated by the Sudoku Reasoning Team. We take your privacy seriously. This Privacy Policy explains how the App handles your information.

Information Collection

The App does not collect any personal information.

Specifically:

  • No collection of names, emails, phone numbers, or other personal identifiers
  • No collection of device identifiers (IDFA, UUID, etc.)
  • No collection of location data
  • No collection of usage behavior data
  • No use of analytics or tracking services
  • No third-party SDKs

Data Storage

All App data is stored locally on your device:

  • Current in-progress board (givens, current entries, candidate notes, timer, hint count)
  • Local practice stats (completed count, total hints, streak, last 7 days completions)
  • Daily puzzle records (date, completion flag, elapsed time)
  • Settings (high-contrast toggle, sound effects toggle)

This data:

  • Is stored only on your device (using iOS UserDefaults)
  • Is not uploaded to any server
  • Is not shared with any third party
  • Is deleted when you uninstall the App

Network Connection

The App runs completely offline and does not use any network connection.

The puzzle bank, hint engine, and daily-puzzle seed are all bundled local resources and algorithms.

Third-Party Services

The App does not include any third-party services or SDKs, no ad networks, no analytics, no crash reporting, no social sign-in, and no cloud sync.

System Permissions

The App requests no system permissions — no camera, photos, location, notifications, microphone, contacts, or health data.

App Tracking Transparency (ATT)

The App performs no tracking and does not show an ATT prompt. The submission declares NSPrivacyTracking = false and ships a PrivacyInfo.xcprivacy manifest stating zero data collection.

Children's Privacy

The App does not knowingly collect any information from children under 13. Since the App does not collect any information at all, it is suitable for all ages.

Data Security

Since the App does not collect or transmit any data, there is no risk of data breach. All game data is stored on your device and protected by your device's security mechanisms.

Your Rights

You can at any time:

  • Delete all local data by uninstalling the App
  • Clear the current unfinished board via "Settings → Clear Current Progress" (cumulative stats remain)
  • Manage permissions through "Settings → Privacy & Security" on your device (the App requests none, so no entry will appear)

Changes to Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be communicated through app updates. We recommend reviewing this policy regularly. The current v1.0 commits to remaining fully offline.
