TwinChess respects your privacy. This Privacy Policy explains what information the TwinChess app collects, how that information is used, and what choices are available.
TwinChess is intended for children and families. A parent or guardian should review this Privacy Policy before the app is used by a child.
TwinChess is a single-player puzzle game.
TwinChess:
TwinChess does not ask users to provide:
After this Privacy Policy has been accepted, TwinChess may collect limited analytics information through Firebase and Google Analytics.
This information may include:
TwinChess uses analytics information only to understand how the app is used and to improve gameplay, usability, stability, and performance.
TwinChess does not use analytics information for advertising, advertising personalization, user profiling, personalized recommendations, or account-based personalization.
TwinChess may use Firebase Crashlytics to help detect, understand, and fix crashes and stability problems.
If Crashlytics is enabled, it may collect diagnostic information such as:
Crash reports are used only to improve app stability and fix technical issues.
TwinChess does not intentionally include names, email addresses, account IDs, or other direct identifiers in crash reports.
TwinChess is designed so that analytics and crash diagnostic collection starts only after this Privacy Policy has been accepted.
Before acceptance, TwinChess should not send analytics events or crash diagnostic reports.
The app may store a local record on the device showing that the current version of this Privacy Policy has been accepted.
TwinChess may store game-related data locally on the device, such as:
This local data is used to operate the app on the device.
Deleting the app, clearing app data, or resetting the device may delete this local data.
TwinChess is intended for children and families.
The app does not require children to create an account or submit direct personal information such as a name, email address, phone number, photo, or message.
The app may collect limited analytics and diagnostic information after this Privacy Policy has been accepted, as described above. This information is used to operate, maintain, and improve the app.
If you are a parent or guardian and believe that TwinChess has collected information from a child in a way that is not described in this Privacy Policy, please contact us at den@denvo.io.
TwinChess does not show ads.
TwinChess does not use advertising SDKs.
TwinChess does not use analytics information for advertising personalization.
TwinChess does not allow users to upload, publish, share, exchange, or display user-generated content inside the app.
TwinChess does not include chat, messaging, comments, public profiles, friend lists, or social networking features.
If the app includes a device-level sharing option, such as sharing a game result image through the operating system share sheet, that sharing is controlled by the user and by the selected external app. TwinChess does not host or publish shared content.
TwinChess may use the following Google services:
These services help us understand app usage and diagnose technical problems. Google may process information according to its own privacy and data processing terms.
We do not sell personal information.
We may share limited analytics and diagnostic information with service providers that help us operate, maintain, and improve TwinChess, including Google Firebase, Google Analytics, and Firebase Crashlytics.
We may also disclose information if required by law, regulation, legal process, or to protect the rights, safety, and security of users, the app, or others.
Analytics and diagnostic information is retained according to the retention settings configured in Firebase, Google Analytics, and Firebase Crashlytics.
Local game data remains on the device unless the app data is cleared, the app is uninstalled, or the operating system removes the data.
You can stop future analytics and diagnostic collection by uninstalling the app.
You can clear local app data through device settings, where supported by the operating system.
Because TwinChess does not use accounts, we may not be able to identify or delete a specific user’s analytics or diagnostic records without additional technical identifiers.
We use reasonable technical and organizational measures to protect information processed by the app and by our service providers. However, no method of electronic storage or transmission is completely secure.
We may update this Privacy Policy from time to time.
When we update this Privacy Policy, we will update the effective date above.
If a new version of this Privacy Policy requires acceptance, TwinChess may show the privacy policy screen again before the game starts.
