With an upcoming update to its mobile apps, Twitter will begin amassing information on what apps its users have downloaded onto their devices. This data can be collected on both Android and iOS devices – it runs a query for the names of the apps you have installed.
Twitter says the information will help it deliver more relevant promoted content, as well give better suggestions on who to follow.
The program is opt-out, so everyone’s data will be automatically collected unless you choose to turn the feature off. Users will receive a prompt as the feature goes live, however, and you can turn the feature off or back on via your respective settings menu.
