Advertising & privacy choices

An app can calculate locally and still process information through its advertising services.

Why advertising uses information

Google AdMob may process identifiers, IP addresses, app interactions, and diagnostic information for ad delivery, measurement, analytics, and fraud prevention. The specific processing depends on the app's SDK and advertising settings.

Personalised, non-personalised, and limited ads

Personalised ads may reflect interests or activity where permitted. Other ad modes can reduce personalisation or identifier use, but do not necessarily eliminate all data processing.

Managing choices in the app

If your app version displays a privacy or consent message, review the available options. Where a privacy-options control is provided, you can return to it to change your preferences. This website cannot change consent stored by the mobile app or its advertising providers.

Managing device settings

Android's advertising settings may let you reset or delete your advertising ID. Available options vary by device and Android version. You can also review Google My Ad Center and Google's advertising information.
