Hamdoku: Sudoku Puzzle · Last updated: October 31, 2026

These Terms & Conditions ("Terms") are an agreement between you and Om Software ("we", "us", "our") about your use of the Hamdoku: Sudoku Puzzle app ("the app"). By installing or using the app you agree to these Terms. If you do not agree, please do not use the app.

1. The app

Hamdoku is a free puzzle game. Some features may change, be added or be removed over time. The app is free to download and play and is supported by advertising. At the time of writing it has no paid purchases.

2. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the app on your devices for your own non-commercial entertainment, subject to these Terms and to the rules of the app store you downloaded it from (Apple's App Store or Google Play).

3. What you may not do

  • Copy, modify, translate or create derivative works of the app or its content.
  • Reverse engineer, decompile or try to extract the source code, except where the law allows it despite this restriction.
  • Sell, rent, lease, sublicense or distribute the app or access to it.
  • Remove or bypass any copyright notice, security feature, or the display and measurement of ads.
  • Use bots, scripts, cheats, tampered copies or other automated means to change game progress, coins or ad results.
  • Interfere with the app, the services it relies on, or other people's use of them.
  • Use the app for any unlawful purpose.

4. Ownership

The app, including its name, artwork, characters, animations, audio, puzzles, code and design, is owned by Om Software or its licensors and is protected by copyright and other laws. These Terms do not give you any ownership rights. All rights not expressly granted are reserved.

5. Virtual coins and progress

Coins and other in-game items are earned by playing. They have no cash value, cannot be exchanged for money or anything of value, and cannot be transferred. Your progress is stored on your device. If you delete the app, clear its data or change devices, your progress may be lost, and we cannot restore it.

6. Ads and third-party services

The app shows ads and uses third-party services such as Google AdMob, Firebase and push notification providers. Ads may link to third-party websites or apps. We do not control and are not responsible for third-party content, products or services, and your dealings with them are governed by their terms. How information is handled is explained in our Privacy Policy.

7. Updates

We may release updates to fix problems or add features. Some updates may be required for you to keep using the app, and the app may prompt you to update. Older versions may stop working.

8. Availability

An internet connection is not needed to play, but some features (such as ads, updates, notifications and remote settings) need one. We do not promise that the app will always be available, uninterrupted or error free. We may suspend, change or discontinue the app at any time.

9. Disclaimer of warranties

To the fullest extent permitted by law, the app is provided "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of merchantability, fitness for a particular purpose, and non-infringement. Some places do not allow certain disclaimers, so some of this may not apply to you.

10. Limitation of liability

To the fullest extent permitted by law, Om Software will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, progress, profits or goodwill, arising from your use of or inability to use the app. Our total liability for any claim relating to the app will not exceed the amount you paid for it, which, as the app is free, is zero. Nothing in these Terms limits liability that cannot be limited by law.

11. Termination

You can stop using the app at any time by uninstalling it. We may suspend or end your access if you break these Terms. Sections that by their nature should continue (such as ownership, disclaimers and limits of liability) will continue after termination.

12. Age

The app is a general-audience game. If you are under the age of majority where you live, please use it with a parent or guardian's permission. See the Privacy Policy for details about children's privacy.

13. Apple and Google

If you downloaded the app from the Apple App Store, you acknowledge that these Terms are between you and Om Software only, not Apple. Apple has no obligation to provide maintenance or support for the app, and is not responsible for claims relating to it. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Similarly, Google is not a party to these Terms for apps downloaded from Google Play. You must also follow the terms of the app store and any third-party terms that apply, such as those of your mobile carrier.

14. Changes to these Terms

We may update these Terms from time to time. The "Last updated" date at the top shows when they last changed. If you keep using the app after a change, you accept the updated Terms. If you do not agree, stop using the app.

15. Governing law

These Terms are governed by the laws of India, without regard to conflict of law rules, unless your local consumer protection laws require otherwise. Subject to any mandatory rights you have, courts in India will have jurisdiction over disputes about these Terms.
