This Privacy Policy describes how the Android game "Knurl: Screw Sort Puzzle" (the App) handles information. The App is developed by AppVita Studio.
INFORMATION THE APP COLLECTS
The App itself does not ask for, collect, or store any personally identifying information. There is no account and no sign-in. Your game progress, coins, stars and settings are stored only on your device and are removed when you uninstall the App.
ADVERTISING
The App is free and supported by ads served through Google AdMob. To show ads, Google and its advertising partners may collect and process certain data, such as your device advertising identifier (Advertising ID), approximate location derived from your IP address, and app-interaction data, in accordance with Google's own policies. See Google's Advertising policy (https://policies.google.com/technologies/ads) and the Google Privacy Policy (https://policies.google.com/privacy) for details.
Where required by law, the App shows a consent dialog (Google UMP) the first time you open it, so you can choose whether this data is used for personalised advertising. You can reset or limit ad personalisation at any time in your device settings (Settings > Google > Ads).
CHILDREN
The App is not directed to children under 13 and does not knowingly collect personal information from children.
DATA SECURITY
Game data stays on your device. We do not operate any server that stores your data. Data sent to Google's advertising services is transmitted over a secure connection.
DATA DELETION
Uninstalling the App deletes all data it stored on your device.
CHANGES
We may update this policy; changes will be posted on this page with a new "Last updated" date.
