My Waypoints utilizes advertising revenue to support the developer. Advertising in the app is provided by AdMob. AdMob may use the advertising ID from the device on which the ad is serving to generate interests and demographics (for example, ‘sports enthusiasts’). Interests, demographics, and other data may be used to serve better targeted ads to the user.
If you purchase the premium upgrade to the app the AdMob technology will no longer be activated.
If you are concerned about the data collected and wish to disable all or some personalized advertizing you may do so at https://www.google.com/settings/ads.
