Cookies and Similar Technologies Policy

Last Updated: 13 December 2019

TransferWise uses small files (known as cookies) to see how you use our site and products. We put them on your computer when you visit our site, and use themto recognise you and store information in between visits.

With cookies we can give you a better browsing experience, improve the quality of our products, and keep our marketing costs down. They let us make it easier tolog in, and they show us where you might be having trouble with our products. Without them, we’d have no way to remember anything about you, such as whetheryou’re logged in.

In this policy, we’ve explained how and why we use cookies, and what each of them do. We’ve broken them down into four groups:

  • Strictly necessary cookies. We need these cookies to run our website — they let us save your cookie preferences, and keep the site secure. They’realways on.

  • Cookies that give you a better browsing experience. These let us tailor the site to your needs, like displaying it in the same language as your webbrowser. We’ll sometimes refer to them as functionality cookies.

  • Cookies that help us improve our products. These let us use tools that show us how you interact with our products — Mixpanel, for example. They helpus find and fix problems for our customers, and they’re also known as analytical or performance cookies.

  • Cookies that keep our marketing costs down. These improve our marketing — helping us to spend less on sites like Google and Facebook, and moreon charging as little as we can. When our costs go down, so do our prices. We share this information in aggregate form with third parties, for the purposeof advertising.

You can see each cookie we use and our reasons for using them below.

Facebook The _fr, _fbbp, _tr, AA003 and ATN cookies are used by Facebook to obtain encrypted data about visitors and users of our website for the purposes of measuring advertising effectiveness, showing relevant advertising to certain groups of users and excluding other groups of users from seeing irrelevant advertising.

For example, if a user registers on, the cookie will share with Facebook encrypted emails used to register with TransferWise in the form of a hash. If you have an account with Facebook, Facebook will be able to identify you as the same user on Facebook that has registered for TransferWise. If you don’t have an account, this hash renders useless, and as such ‘new’ information previously unknown to Facebook is not shared with Facebook.

In this example, we can measure the effectiveness of our Facebook advertising. It helps us understand how many users have registered with TransferWise via Facebook. This is important as it means we can make informed investment decisions about our advertising. This may help us contribute to our overall mission of reducing prices for customers over time.

This can also help us prevent advertising irrelevant content to users, e.g. advertisements encouraging users to sign upto TransferWise when they have already done so.
