Twitter Says It May Have Shared User Data With Ad Partners Without Permission

LOADING ERROR LOADING Twitter apologized this week after admitting that it may have mistakenly shared user data with third parties and used data for personalized ads without first obtaining user permission. According to the post, Twitter users who have clicked or viewed an ad on the platform’s mobile app since May 2018 may have had certain data — such as their country code and their engagement with the ad — shared with third-party measurement and advertising partners even if they hadn’t given consent to Twitter to share such information. Twitter said that since September 2018, some users may have also been shown ads “based on inferences we made about the devices you use, even if you did not give us permission to do so.” That data stayed within Twitter, the company said, and “did not contain things like passwords, email accounts, etc.” We recently discovered and fixed issues related to your settings choices for the way we deliver personalized ads, and when we share certain data with trusted measurement and advertising partners. We want to share more context around this with you: https://t.co/jDn5zeWVwU — Twitter Support August 6, 2019 Twitter said it was still conducting an investigation into its “mistake” to determine which users were affected.
