ChesSudoku — Privacy Policy

Last updated: 8 September 2026

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.

What we collect

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.

What the app stores on your device

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.

WhatWhy
Level progress and medalsSo the game remembers what you have cleared
Best timesSo a board can be beaten
SettingsSo your preferences persist
Hints held, and Daily Challenge boards clearedSo hints you earned are still there tomorrow
Counts of how many boards you have finishedSo ads are shown no more often than intended

Advertising

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.

Your consent, and changing it

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.

Children

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.

Deleting your data

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.
