NeuroChess
Privacy Policy
Effective date: November 13, 2026
Short version: NeuroChess has no account and keeps your scores, ranks and settings only on your device. We do not collect or sell your personal information. The free version shows non-personalised ads from Google AdMob, which receives some device data in order to deliver them. Any purchase removes ads.
1. Information We Collect
The NeuroChess mobile application (N-Back, Sequences, Combos, Chess Puzzles, Deep Chess) stores all user data exclusively on your device using a local SQLite database. This includes:
- Game session history (scores, accuracy, duration)
- Earned ranks and progress per game mode
- App settings and preferences
- Purchase status (stored locally via AsyncStorage)
None of this data is transmitted to our servers or any third party. The only data that leaves your device is what the advertising service described in section 2 collects, and only while ads are shown.
2. Advertising
The free version of the app (version 2.0 and later) shows full-screen ads between games, provided by Google AdMob. When no ad is available, for example when you are offline, the app shows its own notices about the Store instead; those use no data.
We request non-personalised ads only. Ads are not chosen using a profile of your interests or your activity in other apps, and the app does not ask for permission to track you across apps and websites.
To deliver and measure ads and to prevent fraud, Google's advertising software in the app may collect and send to Google:
- Device and advertising identifiers (for example the Android advertising ID)
- Your IP address, from which an approximate location (country or city) can be derived
- Ad interactions, such as which ads were shown or tapped
- Diagnostic information, such as device model, operating system version and app performance data
This data goes to Google, not to us; we never receive or store it. Google uses it as described in How Google uses information from sites or apps that use its services and the Google Privacy Policy.
Your choices.
- Any purchase in the Store removes all ads, and with them all advertising data collection.
- In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent before ads are shown. You can change your choice at any time in the app under Guides → FAQ → Ad Privacy Choices.
- You can reset or delete your advertising ID in your device settings (Android: Settings → Privacy → Ads).
Tapping an ad opens the advertiser's page or app store listing. From that point the advertiser's own privacy policy applies.
3. In-App Purchases
In-app purchases are processed through Apple App Store (iOS) or Google Play (Android). NeuroChess does not receive or store your payment details. Purchase status is validated via the respective platform and stored locally on your device. For questions about a charge, please contact Apple or Google support directly.
4. Crash Reporting & Analytics
The app does not use crash reporting or analytics of our own. If we add crash reporting in a future version, we will update this policy first. The NeuroChess website (neurochess.com) uses Google Analytics to track aggregate page traffic. Nothing links your use of the website to your use of the app.
5. Children's Privacy
NeuroChess is intended for people aged 13 and over and is not directed at children under 13. We do not knowingly collect information from children. If you believe a child has provided us with information, please contact us.
6. Data Storage & Deletion
Your scores, ranks, settings and purchase status are stored locally on your device. To delete them, uninstall the app. Because they are stored only on your device, we have no ability to retrieve or delete them remotely. There is no account system and no cloud backup. Data collected by Google for advertising (section 2) is held by Google and is managed through your Google and device settings.
7. Third-Party Links
The app and website may contain links to third-party websites (advertisers, app stores). We are not responsible for the privacy practices of those sites. We encourage you to review their privacy policies before providing any information.
8. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the effective date above and post the revised policy at neurochess.com/privacy. Continued use of the app after changes constitutes your acceptance of the new policy.
