What data is used to make offers relevant?
You may see offers in a variety of formats (text, image, video) on sites and apps that partner with Google, also known as the Google Display Network. To help you get the most relevant offers, offers you see may be based on the content of the site you’re viewing and your recent geographic location.
To give you better results for your location, the Google Offers and Google Maps apps use your device's location. Sometimes these apps will save your location information to your Location History. You can manage or delete Location History for your Google Account on the Location History website.
If you no longer want to get relevant offers, you can update your settings.
