This will show you all of the information about you that Twitter has calculated based on your profile and activity. Among the options in this section is one to "personalize across your devices".

The company wants to show you just how much it values their privacy, so it's giving you access to "a suite of industry-leading tools to give you more access to your information and greater, more granular control over how it's used".

Twitter has also changed its stance on "Do Not Track" since the time it joined the movement five years ago. "This encompasses users" age, gender, language, what devices they use to access Twitter, places they've been and a number of other bits of information companies will gobble up to spit out what they think is the most enticing way to get you to buy what they're selling.
The update also includes new rules on sharing data with partners.
Data sharing: Twitter has updated how it shares non-personal, aggregated, and device-level data, including through some select partnership agreements.
