Last updated: 2026-08-01 (v1.2.4 — added Anonymous Usage Statistics section)
This Privacy Policy describes how Holdingline ("the App") handles user information.
The App collects no personal data. Game progress (level, mastery badges, best scores) is stored locally on your device using iOS UserDefaults and never leaves it. The only thing the developer receives is the anonymous usage counts described under "Anonymous Usage Statistics" below.
To decide which motifs and screens are worth maintaining, the App sends anonymous usage counts to a server operated by the developer (collect.appline.app, on Cloudflare). What is counted, all as totals (aggregates) only: how many times the app is opened, a game is started, a game-over is reached, a wave is advanced, the collection or leaderboard screen is opened, and an interstitial ad is requested.
What is sent (only this): a fixed, predefined event name plus the app version number. Nothing else.
What is never sent: no name, email, device identifier (IDFA / IDFV), advertising ID, location, scores, or which motif you played.
No individual can be identified or tracked through these counts: the App assigns no persistent identifier to a device or user for this purpose (no device ID, no session ID). All that is stored is "how many times, in total, something happened" — there is no key to join these counts on, so they cannot become a per-player log or profile. Your IP address is not logged, stored, or used.
These counts are separate from advertising. They go only to the developer's own server and are never combined with anything Google AdMob collects, nor shared with Google, Firebase, Meta, or any other third party. The ATT prompt described below concerns AdMob only; these anonymous counts do not depend on your answer to it and are not tracking under ATT.
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, at a low frequency).
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:
collect.appline.app) for the anonymous counts described above — not a third party, and no advertising or analytics SDK is involved.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).
