One Line City (the game) is made by Teo Michielli. This policy explains what happens to information when you play.
Your progress, coins, cars, roads, trails and settings are saved only on your device. There are no accounts and no game servers, so we never receive or store this information.
The game shows optional rewarded video ads through Google AdMob. To show and measure ads, Google may process your device advertising identifier, IP address, approximate location, device information and ad interaction data.
On iPhone you are asked whether the game may track you. If you decline, ads still appear but are not personalized. You can change this any time in Settings, Privacy and Security, Tracking. Where required by law, a consent screen appears before personalized ads are shown. See how Google uses this data.
The game is not directed at children under 13, and we do not knowingly collect personal information from them.
The game keeps no account, so there is nothing for us to delete on request. Deleting the app removes everything stored on your device.
Updates to this policy will be posted here with a new date.
