Twitter updated its privacy policies, notifying users how it will share data with marketing partners, including Facebook and Google. Twitter also changed privacy controls that affect how people give their permission for the collection of data used to measure the effectiveness of ads served on its platform.
Twitter users began seeing the advisory about new privacy terms this week, which outlines the ways the company gleans data from visitors to its sites and apps, and uses it to advertise on outside platforms like Facebook.
"Twitter shares certain non-public personal information with certain digital advertising platforms to help measure and optimize the effectiveness of our efforts to market Twitter on those platforms,” Twitter said in the privacy update.
Twitter specified that it shares IP addresses and advertising device IDs to target ads on Facebook and Google ad platforms. The inclusion of Facebook appears to represent a new course in Twitter’s advertising strategy. Until recently, Twitter did not run app-install campaigns on rival Facebook to grow its user base.
Twitter declined to comment for this story beyond its privacy announcement online.
