Scope of this policy
This policy applies to the Whisker Sudoku app for Android
(package com.thecoffeelayer.sudoku), published on Google Play by
Coffee Layer, LLC (“Coffee Layer”, “we”, “us”).
The Coffee Layer website has its own privacy policy.
What the game itself collects
The game itself collects nothing. There is no account and no sign-in, and the game does not ask for your name, email address, contacts, photos, or location.
Your puzzle in progress, your settings, your best times and your statistics are stored only on your device, inside the app. They are never sent to Coffee Layer. They are removed when you clear the app’s data or uninstall the app.
Puzzles are generated on your device. The game does not load its content from the internet.
Advertising
Whisker Sudoku is free and shows one banner advertisement at the bottom of the screen. The banner is provided by Google AdMob through the Google Mobile Ads SDK. The app shows no full-screen, video or pop-up ads.
To show and measure ads, Google and its partners may collect and use information from your device. According to Google, the Google Mobile Ads SDK automatically collects:
- your IP address, which may be used to estimate your general location;
- interactions with the app and with ads, such as app launches and taps;
- diagnostic information, such as app launch time and energy usage;
- device identifiers, including the Android advertising ID and the app set ID.
Google uses this information for advertising, analytics and fraud prevention. It is sent to Google over an encrypted connection. Coffee Layer does not receive the information in a form that identifies you; we see only summary reports, such as how many ads were shown.
Google explains its practices in How Google uses information from sites or apps that use our services (opens in a new tab) and in the Google Privacy Policy (opens in a new tab).
Your choices about ads
- Consent. In regions where the law requires it, including the European Economic Area, the United Kingdom and Switzerland, the app asks for your choice before any ad is requested. You can change that choice at any time from Settings, then Ad privacy options, inside the app.
- Advertising ID. You can reset or delete your advertising ID in Android settings, under Privacy, then Ads. Deleting it stops apps from using it to personalise ads.
- Personalised ads. You can manage ad personalisation for your Google account at myadcenter.google.com (opens in a new tab).
What the platforms record
Google Play records installs of the app and, from users who have opted in on their device, crash and performance data. Google shares that with us in summary form so we can fix problems.
This website is delivered by Cloudflare, which logs standard technical information about requests for its pages, including this one, as described in the website privacy policy.
Children
Whisker Sudoku is intended for a general audience aged 13 and over. It is not directed at children under 13, and we do not knowingly collect personal information from them.
Deleting your data
Everything the game stores is on your device. To delete it, clear the app’s storage in Android settings or uninstall the app. Because the game sends nothing to us, there is nothing for us to delete on our side. For data held by Google in connection with ads, use the Google controls linked above.
Changes to this policy
We may update this policy from time to time. When we do, we will change the “last updated” date at the top of this page.
