Sudoku Voyage Terms of Service

1. Purpose

These terms govern use of the Sudoku Voyage app ("the service") provided by H1Soft ("the team").

2. Effect

These terms take effect when you install or use the service. If you do not agree, do not use the service; uninstalling the app ends your use of it.

3. What the service does

The service provides sudoku puzzles across 12 regions with 20 stages each, six technique-based difficulty levels, a three-step Smart Hint with an Academy, postcard and passport-stamp collectibles, a daily puzzle and home widgets. Everything runs on device, without a network connection.

4. Fees

Pricing and any paid features are as stated in the store listing and in the app. If we introduce paid features or change pricing, we will announce it in these terms and in the app before it takes effect.

5. Accounts

The service requires no sign-up and no login. There is therefore no suspension or account-closure process; you end your use by uninstalling the app.

6. Your obligations

You must not:

• use the service to break the law or infringe the rights of others
• reverse engineer, decompile or modify the service, or build derivative works from it
• redistribute, sell or rent the service or any part of it without the team's consent

7. Progress and moving devices

The service has no accounts, so it does not sync between devices automatically. Progress moves only by exporting a backup file in Settings and importing it on the new device.

If you uninstall the app or reset the device, progress that was not exported cannot be recovered.

8. Responsibility for your data

Service data lives only on your device, so it cannot be recovered if the device is lost or reset or the app is removed. The team keeps no backup and offers no recovery. Export anything important and store it yourself.

9. Intellectual property

Rights in the service and its components — source code, design, trademarks and icons — belong to the team or its rightful owners. Whatever you create or scan with the service is yours; the team claims no rights in it.

10. Open source notice

The service includes open source software. Full licence texts and copyright notices are available in the app under "Open source licences".

11. Disclaimer

The service is provided "as is" with no warranty of fitness for a particular purpose. To the maximum extent permitted by law, the team is not liable for indirect, incidental or consequential damages arising from use of the service. This does not limit liability for the team's wilful misconduct or gross negligence.

12. Changes to the service

The team may change or discontinue the service. If the service is discontinued, we will give at least 30 days' notice in the app and in the store listing.

13. Changes

When this terms changes, we post the change and its effective date on this page and in the app. Changes unfavourable to users are announced at least 30 days before they take effect.

14. Governing law

These terms are governed by the laws of the Republic of Korea. Disputes fall under the court with jurisdiction under the Korean Civil Procedure Act as the court of first instance.
