Mmmm!! Cookies! Oh wait, not that kind of cookie... this kind of cookie:

When you visit Twilio’s website, www.twilio.com, or the Twilio Account Portal, we and our service providers acting on our behalf automatically collect certain data using tracking technologies like cookies and web beacons. This notice describes what tracking technologies we use and what we use them for.

What’s a Cookie?

A cookie is a piece of data contained in a very small text file that is stored in your browser or elsewhere on your hard drive. Cookies allow Twilio to identify your device as you navigate through our publicly-accessible website (the Twilio Site) or our account portal. We also use them to recognize return visitors to the Twilio Site. This helps make navigating and interacting with the Twilio Site and our account portal more efficient, easy and meaningful.

By themselves, cookies do not identify you specifically. Rather, they recognize your web browser. So, unless you identify yourself specifically to Twilio, like signing into the account portal, we don’t know who you are just because you visited the Twilio Site.

Twilio uses both session and persistent cookies. Session cookies are cookies that disappear from your computer or browser when you turn off your computer. Persistent cookies stay on your computer even after you’ve turned it off.

You can turn off your web browser’s ability to accept cookies. But, if you do that, certain parts of the Twilio Site or account portal may not work for you.

What’s a Web Beacon?

We use web beacons along with cookies to gather data about use of the Twilio Site and account portal and interaction with emails from Twilio. Web beacons are clear electronic images that can recognize certain types of data on your computer, like cookies, when you viewed a particular website tied to the web beacon, and a description of a website tied to the web beacon. For example, we may put web beacons in marketing emails that notify us when you click on a link in the email that directs you to the Twilio Site or one of its pages. We use web beacons to operate and improve the Twilio Site and email communications.

What We Do With IP Addresses

When you visit the Twilio Site, account portal, or use our products and services, like our APIs, we collect your IP addresses to track and analyze information about the devices that are connecting to our systems and about where those devices are located. For example, we use IP addresses to track which regions visitors to our Twilio Site or Customers logging into our account portal come from and to detect possible fraud.

How We Treat Do Not Track Signals/California Do Not Track Disclosure

Various browsers allow a “do not track” (DNT) setting that relies on a technology known as a DNT header, which sends a signal to websites visited by the individual about the individual’s browser DNT setting. At this time, there is no general agreement on how companies like Twilio should interpret Do Not Track signals. Therefore, Twilio does not currently commit to respond to DNT signals, whether that signal is received on a computer or on a mobile device. Twilio does, however provide meaningful choices to you about the information that is collected through cookies and web beacons through the various opt-out options set forth above. We will continue to monitor developments around DNT browser technology and the implementation of a standard.
