1. Scope and contact
This policy applies to Catdoku, operated by Wonyoung Jang. Catdoku is a separate app from Cat Nest / Cat Ball Sort. Privacy contact: nex5turbo.app@gmail.com.
2. Game and online information
Catdoku stores game progress and preferences on your device. Online features use Firebase Authentication, Cloud Firestore and Cloud Functions to process a pseudonymous user identifier and the game or access records needed for those features, including rankings and tester access where available. Public rankings may show the player name and game statistics submitted for display; avoid putting personal contact details in a player name.
Firebase Remote Config retrieves app settings. Firebase Analytics processes app and device information, pseudonymous identifiers and usage events such as screen views and gameplay outcomes to help us understand app use and improve the game.
3. Advertising and choices
Google AdMob provides advertising. Its SDK may process IP addresses and approximate location, advertising or device identifiers, ad impressions and interactions, crash information and diagnostics for ad delivery, measurement and fraud prevention. Available formats and placement depend on the app version and configuration.
The app uses Google's consent tools and, on supported iOS versions, App Tracking Transparency choices where applicable. You can revisit advertising privacy options where offered and manage tracking permissions in device settings. Refusing tracking does not remove all data processing needed to display ads.
4. Providers and international processing
Google Firebase provides online game services, settings and analytics. Google AdMob provides ads. Apple and Google provide app distribution and device services. The policy website is hosted by Vercel, which may process IP addresses, request URLs, browser information and access logs for delivery and security; see the Vercel Privacy Notice.
Requests are sent over the network when online features or ads are used. Providers may process data in the United States and other countries where they operate. Provider retention and backups depend on their service terms and settings.
5. Retention and rights
Local progress remains until reset, deletion or app removal, subject to device backups. Online identifiers, ranking and service records may remain after uninstalling; contact us to request access, correction or deletion. We verify the relevant game identity before handling requests. Do not email passwords, authentication tokens or recovery credentials.
Analytics, advertising, security logs and provider backups follow the relevant provider settings and requirements; we do not promise that uninstalling immediately deletes every record. A parent or guardian may contact us about a child's information or applicable rights. We use encrypted network communication and account access controls for online services.
6. Changes
We keep earlier policy versions and update this page when online features, SDKs or data processing change. Material changes are communicated through the app or this page as applicable.
