Twitter updated its privacy policy on Monday to reflect that more of your data will be shared with advertisers.
To help us understand if these ads are effective, we share device-level data, like IP address, with our advertising partners. We don’t share things like your name, email, phone number, or Twitter username.
To help mobile app advertisers understand if the ads they run on Twitter are effective, Twitter shares some device-level data, like which ads your device may have seen or clicked on, with them. We don’t share your name, email, phone number, or Twitter username.
It doesn’t matter if they don’t share details like your phone number if it gets leaked anyway.
