Privacy Policy

1. Scope and operator

This policy applies to the corporate website operated by COULEUR at couleur-works.com and to the handling of data in Ghostar v1.1 as described on this page. The operator is COULEUR / COULEUR WORKS. Contact us at admin@couleur-works.com.

Separate privacy information may apply to an individual shop, media property or third-party service. Where such information is provided, please read it together with this policy.

2. Information handled by this website

This website has no login, user accounts, database or contact form. We do not currently operate first-party analytics on the site, and the site is not designed to set our own advertising cookies.

If you contact us by email, we handle the email address, name, message and any other information you choose to provide so that we can review the inquiry and respond where appropriate.

Hosting and network providers may temporarily process technical information such as an IP address, browser details and access time to deliver the website, maintain security and diagnose faults. Their handling of that information is governed by their own terms and policies.

3. Cookies and analytics

The current corporate website does not use our own analytics or behavioral-tracking cookies. We therefore do not display a first-party cookie consent banner. If we later introduce analytics or another feature that changes this position, we will review this policy and any necessary notice or choice before the change is made.

4. Links to third-party services

This site may link to third-party services in order to present our work and products. These may include the services listed below. Once you leave this website, information handling, cookies, content and terms are governed by the relevant service provider's privacy policy and other terms.

This section concerns links on the corporate website. For third-party services used within the Ghostar app, see sections 7 and 8 below.

• Shopify
• YouTube
• X
• Facebook
• Instagram
• Pinterest
• Substack
• note
• App Store
• Google services

5. Accounts and data handling in Ghostar v1.1

Ghostar v1.1 does not require account registration or login and does not use a backend operated by COULEUR. The app does not ask users to enter or provide their name, email address, precise location, contacts or photos. It does not use iCloud or CloudKit.

Ghostar does use the Google Mobile Ads SDK (AdMob) and Google User Messaging Platform (UMP) SDK for advertising and consent management. Processing by Google and advertising partners is described below.

6. Local storage in Ghostar v1.1

Ghostar v1.1 stores the game data and settings listed below on the user's device. This data is not transmitted to a server operated by COULEUR or sent to Google Analytics or Firebase Analytics.

Data for which the app provides an individual reset control can be deleted with that control. Users can remove local data stored by Ghostar by deleting the app. COULEUR does not hold Ghostar account data on a server.

• App settings and the last selected difficulty
• Match statistics
• The current game state
• A local Match ID (a random UUID used to identify a match on the device, not a device identifier)
• Completed-match count, last-ad time and on-device match identifiers used to control interstitial frequency

7. Advertising and processing by Google in Ghostar v1.1

Ghostar v1.1 uses Google AdMob to show adaptive banner ads on the home and result screens. It evaluates whether to show an interstitial only when the user selects Replay or Home from the result screen and only at a limited frequency. A missing or failed ad does not delay the user's transition.

According to Google's official disclosure, the Google Mobile Ads SDK may process the information listed below for purposes such as ad delivery, advertising measurement, analytics, fraud and abuse prevention, diagnostics, and improvement of the SDK and related services. The information actually processed varies with device settings, region, consent choices, advertising configuration and other conditions.

This processing may be performed by the Google Mobile Ads SDK and advertising partners. It does not mean that COULEUR directly obtains or holds every item as Ghostar account information. Ghostar does not use Google Analytics, Firebase Analytics, a proprietary analytics platform or a proprietary crash-reporting platform.

• IP address, which may be used to estimate the device's general location
• Crash logs not directly related to a user
• Performance data such as app launch time, hang rate or energy usage
• A device ID, such as an advertising identifier or an app- or developer-bounded identifier
• Advertising data, such as ads the user has seen
• Product interactions such as app launches, taps or video views

8. Consent management with UMP

Ghostar v1.1 uses the Google UMP SDK to update consent information when the app starts. Where required by law or Google policy, including applicable users in the European Economic Area (EEA), the United Kingdom and Switzerland, the app presents choices to Consent, Do not consent, or Manage options for advertising and related data processing. If consent is not given, limited ads may still be served under Google's systems.

The Google Mobile Ads SDK is initialized only after required consent handling is complete and UMP indicates that ad requests are permitted. If UMP determines that a privacy options entry point is required, users can review their choices through Advertising privacy settings in the app's Settings screen. UMP stores consent choices locally on the device.

Ghostar does not use Google Consent Mode, Special Feature 2 or consent synchronization across multiple apps.

9. ATT, IDFA, analytics and external communication

Ghostar v1.1 does not implement an App Tracking Transparency (ATT) authorization request and does not include NSUserTrackingUsageDescription in its Info.plist, so it does not display the ATT prompt. It also disables the Google Mobile Ads SDK publisher first-party ID before starting the SDK. Ghostar does not request permission to access the IDFA and is not designed to perform cross-app tracking using the IDFA.

This does not mean that the Google Mobile Ads SDK processes no other app- or developer-bounded identifier, advertising data or diagnostic information. See section 7 and Google's policies for details.

Gameplay itself does not require online multiplayer or communication with a COULEUR server. Ghostar v1.1 does, however, communicate externally to update consent information through UMP and to load, deliver and measure AdMob ads and help prevent fraud. Ghostar does not use a proprietary tracking platform.

10. Use and sharing of inquiry information

We use information received through an inquiry to respond, operate services safely and meet applicable legal obligations. We do not sell information provided to us. Information may be disclosed where required by law, where reasonably necessary to protect rights or safety, or to a service provider processing it for a legitimate operational purpose under appropriate confidentiality obligations.

11. Information management

We apply reasonable access controls and other safeguards appropriate to the nature of the information we handle. No internet transmission or electronic storage method can be guaranteed to be completely secure. Inquiry records are retained with regard to the time needed to respond and maintain appropriate business records, then deleted when no longer reasonably required.

12. Changes to this policy

We may update this policy as our work, website functions, individual products or third-party services change. Material changes will be reflected on this page together with a revised update date.

If we change the advertising, consent-management, analytics or other third-party SDKs used by Ghostar or their configuration, we will review the actual processing and update this policy and the App Store privacy information as necessary.
