Local Game Data

CardNova stores gameplay progress locally on your device. This includes current level, completed levels, star ratings, and local settings such as the music toggle. This data is used only to run the game experience and is not a cloud save.

Advertising and Tracking Permission

CardNova may request permission through Apple App Tracking Transparency before advertising SDKs are initialized. If you allow tracking, the app may access the advertising identifier to support personalized advertising. If you deny tracking, the game remains playable and advertising SDK setup continues without the advertising identifier.

Third-Party SDKs

CardNova includes third-party advertising SDKs, including Chartboost, Yandex Mobile Ads, Vungle, and InMobi. These SDKs are initialized after the tracking permission flow and after the app receives valid dynamic ad configuration. They may process device, ad delivery, impression, click, and diagnostic information according to their own privacy practices.

CardNova also includes HSSecurity.framework. This security SDK is initialized after the tracking permission flow on device builds and may process technical identifiers or diagnostic information for app protection and fraud prevention.

Dynamic Ad Configuration

The app requests dynamic advertising configuration using the app bundle identifier. If valid ad configuration is not returned, supported ad SDKs are not activated for rewarded ad display.

No Account or Gameplay Cloud Sync

CardNova does not require a user account, does not provide online multiplayer, and does not upload saved gameplay progress to a cloud service.

Children

CardNova is not designed to knowingly collect personal information from children. If you believe a child has provided personal information, contact the developer so the issue can be reviewed.

Changes

This policy may be updated when the game changes, when SDK behavior changes, or when App Store requirements change. Updates will be published on this page.
