Our free to download Android apps use Google's AdMob advertising service for non-personalized ads. Coarse (city-level) location data may be used for ad targeting, and cookies or mobile ad identifiers may be used for frequency capping, aggregated ad reporting, and to combat fraud and abuse. Google's privacy policy is available at https://policies.google.com/privacy.

There is a one-off in-app purchase to remove ads from the app, and stop the use of Google's AdMob advertising service.
