Holdingline ("the App") is developed and operated by an independent developer. This Privacy Policy describes how the App handles user information.
The App itself does not collect personal data on developer servers. Game progress (level, mastery badges, best scores) is stored locally on your device using iOS UserDefaults.
Starting from v1.1.0, the App displays advertisements via Google AdMob. Google AdMob may collect device identifiers (e.g., IDFA when granted via App Tracking Transparency, or anonymous identifiers when not granted) to serve and attribute ads. Please see "Advertising (AdMob)" below for details.
The App uses Google AdMob to display interstitial ads (full-screen ads shown between game sessions, approximately every 3 game-overs).
To respect Apple's App Tracking Transparency (ATT) framework, the App will ask for your permission before tracking activity across other companies' apps and websites. You can decline this prompt and the App will function exactly the same — only ads will be less personalized.
Google AdMob's privacy practices, including details on data collection and EU/US user rights (GDPR/CCPA), are documented at: https://policies.google.com/technologies/ads
The App enforces a maximum content rating of "Parental Guidance" (PG) at the SDK level, blocking sexual content, dating, gambling, alcohol/tobacco promotion, and similar categories from appearing as ads. We additionally block sensitive ad categories on the AdMob console.
If you choose to sign in to Game Center (a service provided by Apple), the App submits your game scores to Apple's leaderboards. Score submission is handled entirely by Apple's GameKit framework. The developer does not have access to your Game Center identity or scores beyond what is publicly visible on the leaderboard.
Game Center is governed by Apple's privacy policy: https://www.apple.com/legal/privacy/
The App stores progress data (level, mastery badges, best scores) locally on your device using iOS UserDefaults. This data never leaves your device.
The App integrates with the following third-party services:
The App is suitable for ages 9 and up. It does not knowingly collect data from children under 13 (or the equivalent age in your jurisdiction).
