Chess AI Privacy Policy

Effective: October 6, 2026 (previous policy: September 28, 2026) · 한국어

Chess AI (the "app") is provided by Plabit (the "developer"). This policy explains how information is handled when you use the app.

1. Summary

• The developer does not collect or store your personal information. There are no accounts and no developer servers.
• All app data — games, grade, settings — is stored only on your device. The chess engine (AI) runs on your device.
• The app shows ads from Google AdMob. An ad appears only when you choose "watch an ad", and Google then processes some device information needed to serve it (section 3).
• The app does not request personalized ads and does not use the advertising ID permission.

2. Data stored only on your device

The following data is kept in the app's local storage on your device. The developer cannot access it.

• Profile (the name you enter, your chosen piece, grade and rating, exam stamps, achievement cards)
• Game records (moves, time used, number of takebacks and hints, results, analysis)
• Solved puzzles and completed lessons
• Daily usage (games played, hints used and ads watched that day) — used only to work out the free daily allowance
• App settings (language, theme, board colours, sound, etc.)

The profile name is only shown on screen and never leaves your device. Uninstalling the app removes all of this data. You can also erase it with "Reset game data" in Settings.

If Android backup (Google account backup) is turned on for your device, the Android system may include this data in your own Google account backup. That backup is governed by Google's policies and the developer cannot access it.

3. Advertising (Google AdMob)

The app uses Google AdMob (the Google Mobile Ads SDK) and Google's consent tool (User Messaging Platform), provided by Google LLC.

When ads appear

• Ads appear only when you choose them, by tapping a "Watch ad" button:
  • to play one more game after the free games of the day are used
  • to get more hints
  • to take back a move in a game against the AI
  • to play an opponent above your grade's level in a free game
  • to try a puzzle above your puzzle level, or to retry a puzzle you have attempted
• No ad appears automatically. There are no banner ads and no ads between screens. Game review, analysis and lessons have no ads.

Information processed by Google

When an ad is requested and shown, the Google Mobile Ads SDK may send the following information to Google, which processes it. The developer does not receive or store this information.

• IP address (which may be used to estimate your general location)
• Device information (model, operating system version, language, screen size, etc.) and app information (name and version)
• Ad interactions (whether an ad was shown, tapped or watched to the end)
• Diagnostic information (errors and performance)
• Identifiers that distinguish a device or an app installation

The purposes are serving ads, limiting how often an ad is shown, measuring ad performance, and fraud prevention and security.

No personalized ads

• The app marks every ad request to be treated as coming from a user under the age of consent. Google therefore does not use personalized advertising or remarketing for these requests.
• The app does not include the Android advertising ID permission.
• Ad content is limited to the general-audience (G) rating.
• The ads you see are based on general information such as the type of app and your approximate region, not on your interests.

Consent and choices

• In the European Economic Area, the United Kingdom, Switzerland and other regions where consent is required, a consent screen is shown the first time ads are prepared. You can use the app without consenting.
• In those regions you can change your choice at any time in Settings › Ad privacy options.
• You can keep using the app within the free daily allowance without watching any ads.

• How Google uses information from sites or apps that use its services
• Google Privacy Policy

4. Network use

The app connects to the internet only to load and show ads. Games, analysis, puzzles, lessons and records work offline, and your games and profile are never sent anywhere.

5. Third parties

The developer does not sell or share your data. The only external service in the app is Google AdMob (Google LLC) as described in section 3; the app contains no analytics tools and no other ad networks. Google may process information in the United States and other countries outside your own.

6. Children

The app is not directed to children under 13 (under 14 in the Republic of Korea) and the developer does not knowingly collect personal information from children. The developer does not ask for or store your age. Regardless of age, every ad request is sent with personalized advertising turned off (section 3).

Parents or guardians with questions about a child's information can contact the address in section 9.

7. Your rights

• You can erase the data on your device yourself with "Reset game data" or by uninstalling the app.
• Because the developer holds no information that identifies you, there is no data held by the developer to access, correct or delete.
• For information processed by Google, follow the procedures in the Google Privacy Policy. You can change ad-related settings on your device under Settings › Google › Ads.
• Depending on where you live (for example under the GDPR), you have the right to lodge a complaint with your data protection authority.

8. Changes to this policy

If this policy changes (for example, if paid features or other external services are added), the change will be announced through an app update or on this page.

• October 6, 2026: sections 3–7 revised for the addition of ads (Google AdMob).
• September 28, 2026: first version (no ads, no network use).
