Twitter has partnered with a number of ad technology companies like Datalogix, Epsilon and Liveramp to make all the targeting work.
If Twitter users do not want to be targeted by advertisers in this way, they can adjust their privacy settings to turn off the matching, the company said. In users' privacy settings, there is an option to "Tailor ads based on information shared by ads partners." If people uncheck that, Twitter will not match people's accounts to information from ad partners, the company said.
