Chalk Kart — Privacy Policy
Last updated: 18 August 2026
This privacy policy describes how the Chalk Kart iOS app ("the app") handles your information. The app is developed and published by Chalke Customs ("we", "us").
Information we collect
The app itself does not require an account and does not collect your name, email address, or contact details. The following data is handled on-device or by third-party services:
- Game progress. Your stars, coins, best race times, and the karts and chalk colours you have unlocked are stored locally on your device. Karts you draw in the app are also stored locally.
- Game Center. If you choose to use Game Center, your career points and race wins are submitted to Apple's Game Center service under your Game Center identity, subject to Apple's Privacy Policy.
- Advertising data. The app shows ads served by Google AdMob. AdMob may collect device identifiers (such as the advertising identifier, where you have allowed tracking), coarse ad-interaction data, and diagnostic information to serve and measure ads. See Google's Privacy Policy and How Google uses advertising data.
- Approximate location. The advertising SDK receives your device's IP address, which may be used to estimate the general area the device is in. This is an approximation drawn from the network connection, not a position from your device: the app never asks for location access and does not use location services.
- Diagnostics. Aggregate crash and performance data may be collected by the advertising SDK to keep the app and ads functioning correctly.
Multiplayer
The 2-4 player mode uses Apple's Game Center real-time matchmaking. When you join a match, your Game Center display name, your chosen kart (including a kart you have drawn in the app, if selected), and your live race position are shared with the other players in that match for the duration of the race. Matchmaking itself is operated by Apple under Apple's Privacy Policy; we do not operate any multiplayer servers and do not store this data.
App Tracking Transparency
On iOS the app asks for your permission before tracking. If you choose “Ask App Not to Track”, your device's advertising identifier is not shared with AdMob and you will see non-personalised ads instead. You can change this at any time in Settings > Privacy & Security > Tracking.
Advertising and consent
In regions where consent is required (such as the EEA and UK), the app presents a consent form powered by Google's User Messaging Platform before showing personalised ads. You can decline personalised ads and still play the game. Ads are never shown during a race.
Children
The app is not directed at children and does not knowingly collect personal information from children.
Data retention and your rights
We do not operate our own servers for this app and hold no personal data about you. Data handled by Google (AdMob) is retained under Google's policies, and data submitted to Game Center is held by Apple under theirs; you can exercise your privacy rights directly with each. You can also reset your device's advertising identifier at any time in iOS Settings, and remove all local game data — including karts you have drawn — by deleting the app.
Changes to this policy
If we change how the app handles data, we will update this page and the "Last updated" date above.
