ChesSudoku is a puzzle game for Android, published by Neuron Gaming
(package com.neurongaming.chessudoku). This policy explains what the app does
with data. The short version: we collect nothing about you, and the only
third party involved is Google AdMob, which serves the ads.
Nothing. The app has no accounts, no sign-in, no analytics, no crash reporting and no telemetry. We do not receive your name, your email address, your location, your contacts, or any identifier for you. There is no server we could send it to.
The app saves your play data locally, in storage private to the app. It is never transmitted anywhere, and it is deleted when you uninstall the app.
| What | Why |
|---|---|
| Level progress and medals | So the game remembers what you have cleared |
| Best times | So a board can be beaten |
| Settings | So your preferences persist |
| Hints held, and Daily Challenge boards cleared | So hints you earned are still there tomorrow |
| Counts of how many boards you have finished | So ads are shown no more often than intended |
The app shows ads supplied by Google AdMob. To do that, Google may collect and process data from your device, including your advertising identifier, IP address, device and operating-system information, and how you interacted with an ad. Google acts as an independent controller of that data; we do not receive it and cannot access it.
How Google uses data from apps that use its services is described at policies.google.com/technologies/partner-sites, and its advertising practices at policies.google.com/technologies/ads.
Two of the three ad placements are optional and are shown only if you choose to watch one in exchange for something in the game. You are never required to watch an ad to keep playing.
If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent before any personalised advertising, using Google's User Messaging Platform. If you decline, ads are still shown but are not personalised.
You can change your choice at any time from Settings → Privacy options inside the app. You can also reset or delete your advertising identifier in Android's own settings, under Settings → Google → Ads.
ChesSudoku is not directed to children, and we do not knowingly collect any information from children. Ad content is restricted to a general-audience rating.
Because everything the app stores stays on your device, uninstalling the app deletes all of it. You can also clear it from Android's Settings → Apps → ChesSudoku → Storage → Clear data. There is no account to close and nothing held elsewhere.
If this policy changes, the date at the top of this page changes with it.
