Sudoku Otter · Privacy Policy

数独水獭隐私政策

Last updated: July 21, 2026

In short: Sudoku Otter does not collect, upload, or share any of your personal information. All data stays only on your own device.

Thank you for using Sudoku Otter (the "App"). We take your privacy seriously. This Privacy Policy explains how the App handles information related to you.

1. Information We Collect

The App does not collect or upload any personally identifiable information. The App has no account system; all features are available without registration or sign-in.

The following data generated while using the App is stored only locally on your device and is never transmitted to us or any third party:

Puzzle progress and records: the state of puzzles you are working on or have completed, completion time, and number solved — used to restore your progress and show "in progress" / "completed" markers.
App preferences: such as whether you have already been prompted to leave a review.

This data is kept in your device's local storage. If you delete the App, this data is deleted along with it.

2. Use of the Camera

The App offers a "scan a Sudoku puzzle with the camera" feature. When you actively use this feature, the system will request camera permission.

Photos you take are processed for text recognition entirely on your device, solely to fill the puzzle into the board automatically. Photos and recognition results are never uploaded, saved, or shared. The photo is discarded once recognition is complete.

If you do not use the scan feature, you may decline camera permission without affecting other features. You can manage camera permission at any time in the system Settings.

3. In-App Purchases & Tips

The App may offer optional tips or in-app purchases. All transactions are processed through Apple App Store In-App Purchase (StoreKit), with payment handled by Apple.

We do not access, collect, or store your payment information (such as card numbers or Apple ID password). Apple's handling of transaction data is governed by Apple's Privacy Policy.

4. Network & Third Parties

The App's core features run entirely offline and require no internet connection. The App:

contains no third-party advertising;
contains no third-party analytics or tracking tools (SDKs);
does not share your data with any third party.

5. Children's Privacy

The App is suitable for users of all ages, including children. Because the App collects no personal information, no personal information about children is collected. We recommend that parents supervise young children's use of electronic devices.

6. Your Rights

Because all data is stored locally on your device, you have full control over it:

You can clear or overwrite your puzzle progress at any time within the App;
You can revoke camera permission at any time in the system Settings;
You can delete the App at any time, which removes all local data.

7. Changes to This Policy

If the App's features change in the future, we may update this Privacy Policy and post the revised version and date on this page. We recommend reviewing this page periodically.
