Last updated: 2026-08-01 (v1.3.1 — added Anonymous Usage Statistics section)
This Privacy Policy describes how Dartline ("the App") handles user information.
The App collects no personal data. Local game state — best Count Up score, settings — is stored 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 game modes 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 match is started (and how many of those were practice or online matches), a match is played to the end, the career stats / play history / leaderboard screens are 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, throw data, or motion-sensor readings.
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.
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.
Dartline uses the iPhone's accelerometer and gyroscope (via the CoreMotion framework) to detect tilt for aiming and throw motion for releasing darts. Motion data is processed entirely on-device in real time and is never transmitted off the device or stored persistently.
The App uses Google AdMob to display interstitial ads (full-screen ads shown between game sessions, after the result screen at a low frequency with cooldown to avoid back-to-back display).
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 Count Up best score to Apple's leaderboard. 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 (Count Up best score, theme preferences) 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 analytics SDK is involved.The App is suitable for ages 12 and up (Apple Age Rating 12+). It does not knowingly collect data from children under 13 (or the equivalent age in your jurisdiction).
