Does Google sell my personal information?

What information does Google share with advertisers?

We give advertisers information about their ads’ performance, but we do so without providing any information that personally identifies you. For example, we may tell an advertiser how many people viewed their ads or installed an app after seeing a certain ad. We may also give advertisers general demographic information, such as “25 to 34 years old, male, travel.”

Some of our ads let you share information to make it easier for you to purchase the products and services you were looking for. For example, when you use services such as Google Flights Search, we send your flight departure/return dates to booking engines so they can come back with the best rates for you.

As another example, when you see a “Call” button in an ad, we make it easy for you to call the advertiser. In these instances, the advertiser might know what number you are calling from.
