Math Solitaire Privacy Policy

1. Information the app collects

The app has no accounts or login and does not directly collect personally identifiable information such as your name, email address, or phone number.

Game progress and settings are stored only on your device and are never sent to the developer's servers.

2. Third-party advertising

To stay free, the app shows ads from Google AdMob, a service of Google LLC. AdMob may collect and process the following to deliver ads, measure performance, and prevent fraud:

• Advertising ID (Android Advertising ID)
• Device information (model, OS version, language) and approximate location based on IP address
• Ad interactions (impressions, clicks) and app usage and diagnostic information

For details, see:

• Google Privacy Policy
• How Google uses information from partner apps

3. Usage analytics (Google Analytics for Firebase)

To improve the game, the app uses Google Analytics for Firebase, a service of Google LLC. No personally identifiable information such as your name or email is sent. The following usage information may be collected:

• App instance ID, device information (model, OS version, language) and diagnostic information
• App interactions, gameplay events, app launches and session length

This information is used only to improve the service, such as game usability, stability and ad frequency.

4. Personalized ads and consent

• In regions that require consent (such as the EEA and the UK), the app shows Google's consent screen (User Messaging Platform) when you first open it, before ads are requested. You can change your choice at any time from the app's Settings.
• Android: reset or delete your Advertising ID in device Settings > Google > Ads.

5. In-app purchases (Google Play Billing)

The app offers an optional one-time "Remove Ads" purchase through Google Play Billing. Payment and purchase records are handled by Google Play. The app uses the purchase record to deliver and restore your purchase. The developer never receives your card or payment details. Google's handling of payment and purchase information is governed by the Google Privacy Policy.

6. Children

The app is not directed at children under 13 and does not knowingly collect personal information from children.

7. Retention and deletion

Game data stored on your device is deleted when you uninstall the app or clear its data. A Remove Ads purchase stays linked to your Google account and can be restored after reinstalling. Analytics and advertising data collected by Google is retained and deleted according to Google's applicable retention settings and policies.

To request deletion of analytics or advertising data collected through the app, email the address below with the app name (Math Solitaire). Because the app has no accounts, please describe your device and when you used the app so we can process the request with Google.
