What changed in v1.1: To improve the App, we added the sending of anonymous usage counts (see "Anonymous Usage Statistics" below). We count totals such as how many times the app is launched or a game is completed. Because the App holds no identifier of any kind, it cannot identify a specific player, track an individual over time, or build a profile. No name, email, device identifier, or location is included. We include this note to be transparent about the change.
This Privacy Policy describes how ABS Challenge ("the App") handles user information.
The App has no account system and collects no personal data. Local game state — scores, accuracy history, team names and colors, and settings — is stored on your device using iOS UserDefaults and never leaves your device. The only thing that leaves your device is the anonymous usage statistics (identity-free event counts) described below.
To make the App better, it sends anonymous usage counts to a server operated by the developer (collect.appline.app, on Cloudflare). What is counted, all as totals (aggregates) only:
What is sent (only this): a fixed, predefined event name plus the app version number. Nothing else.
What is never sent: no name, email, account information, device identifier (IDFA / IDFV), advertising ID, location, or any other information that could identify a person.
No individual can be identified or tracked: the App assigns no persistent identifier to a device or user (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, which makes it structurally impossible to identify a specific player, follow the same person over time, or build a profile.
Where it goes: only to the developer's own server. It is never shared with any third party such as Google, Firebase, or Meta. Your IP address is not logged, stored, or used, and is never associated with the anonymous counts above.
The App contains no third-party advertising and does no tracking across other companies' apps or websites. The anonymous counts above are sent only to the developer's own server, are not linked to your identity, and therefore do not constitute tracking under App Tracking Transparency (ATT). The App does not request ATT permission and does not use the advertising identifier (IDFA).
If you choose to sign in to Game Center (a service provided by Apple), the App submits your best scores — Top Speed (mph), Top Spin (rpm), Best Score, and Best Accuracy — 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 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 (best scores, accuracy history, team names/colors, settings) locally on your device using iOS UserDefaults. This data never leaves your device and is removed when you delete the App.
The App uses only Apple's own frameworks (SwiftUI, SceneKit, GameKit, AVFoundation, Core Haptics). No data is shared with any third party; the anonymous usage counts above go only to the developer's own server.
The App contains no objectionable content. It collects no personal data from anyone; the anonymous usage statistics described above are identifier-free totals that cannot identify any person, including children.
If the App's data practices change in a future version, this Privacy Policy will be updated accordingly before that version is released, with the change noted at the top of this page.
