Whisker Sudoku Terms of Use

The terms that apply when you use Whisker Sudoku, the Android Sudoku game published by Coffee Layer, LLC.

Last updated: 14 November 2026

About these terms

These terms of use govern your use of the Whisker Sudoku app for Android (package com.thecoffeelayer.sudoku), published on Google Play by Coffee Layer, LLC (“Coffee Layer”, “we”, “us”). By installing or using the app, you agree to them. If you do not agree, please do not use the app.

The Coffee Layer website has its own terms of use. Your use of Google Play is governed by Google’s terms, not by this page.

The app

Whisker Sudoku is a single-player Sudoku game. It is free to install and to play. It has no accounts, no sign-in and no in-app purchases. Puzzles are generated on your device, and your puzzle in progress, settings and statistics are stored only on your device.

Licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on Android devices you own or control, for your own non-commercial enjoyment.

The app, including its code, design, text, artwork and the cat character, is owned by Coffee Layer, LLC or used with permission, and is protected by intellectual property laws. These terms do not transfer any ownership to you.

Acceptable use

You agree not to:

  • copy, modify, resell or redistribute the app, except as the law allows;
  • reverse engineer or decompile the app, except to the extent the law gives you that right regardless of these terms;
  • interfere with, block by technical means, or artificially generate views of or clicks on the advertising shown in the app;
  • use the app in any way that breaks the law.

Advertising

The app shows one banner advertisement, provided by Google AdMob. Advertisements are supplied by Google and its partners, not by us. We do not choose, endorse or take responsibility for the products, services or websites that are advertised. If you tap an advertisement, your dealings with the advertiser are between you and them. How advertising uses information from your device is described in the Whisker Sudoku privacy policy.

Updates and availability

We may update the app from time to time, including to fix problems or to change or remove features. We may also stop offering the app. We are not obliged to keep any particular feature or version available.

No warranty

The app is provided “as is” and “as available”. To the fullest extent permitted by law, Coffee Layer, LLC makes no warranties of any kind regarding the app, and does not warrant that it will be uninterrupted, error-free or suitable for any particular purpose. Because your progress is stored only on your device, it can be lost if you clear the app’s data, uninstall the app or change device.

Limitation of liability

To the fullest extent permitted by law, Coffee Layer, LLC is not liable for any indirect, incidental, special or consequential loss or damage arising from your use of, or inability to use, the app. Nothing in these terms limits any rights you have as a consumer that cannot be limited by agreement under the law that applies to you.

Changes to these terms

We may update these terms from time to time. When we do, we will change the “last updated” date at the top of this page. Continued use of the app after a change means the updated terms apply to your use.
