1. The service
Free Sudoku is a free sudoku puzzle game for Android. It offers classic 9×9 puzzles at six difficulty levels, a daily challenge, notes, hints and statistics. The game is free, needs no account and is funded by advertising. We may change, limit or stop any feature at any time.
2. Your puzzles and data
Your games, statistics and settings are stored only on your device. Uninstalling the app, or clearing its data in Android settings, deletes them. Puzzles are generated and solved on your phone, and the game works offline. For details about advertising data, see the privacy policy.
3. Advertising
The game shows ads from third-party advertising networks. Each ad, and any offer it makes, is the responsibility of its advertiser, not of Free Sudoku. Where the law requires your consent to personalized ads, the app asks for it. You can change your choice in the app or in your device settings.
4. Fair use
Use the game lawfully and as intended: play it, enjoy it, get better at it. Do not copy, resell or redistribute the app, interfere with its advertising, or click its ads without a genuine interest in them. You are welcome to share your scores and talk about the game wherever you like.
5. Intellectual property
The Free Sudoku app, its name, its texts and its design belong to the publisher. These terms give you the right to install and use the app for your personal, non-commercial play, and no other right. Sudoku itself, the 9×9 puzzle idea, is in the public domain; this app's implementation of it belongs to us.
6. Liability
The app is provided "as is", without warranty of any kind. To the extent the law allows, we are not liable for losses arising from using the app or from the content of third-party ads shown in it.
7. Your consumer rights
Nothing in these terms limits any rights you have as a consumer under the law of your country of residence.
8. Governing law, changes and contact
These terms are governed by the law of the publisher's country of residence, without prejudice to the mandatory consumer protection rules of your own country of residence. We may change these terms. The date above shows the latest version, and continuing to use the app after a change means you accept it. For any question, contact contact@freesudoku.app.
