By default, Vitally displays your revenue across the platform in USD. However, if you send your revenue to Vitally in a different currency, you can set that currency in your account's Settings.
Changing your currency does not manipulate the data you send us in any way. Instead, it simply changes the currency we use to display your revenue. For example, say you are sending Vitally a value of 80 for an account's revenue. By default, we'll display that as USD (e.g. $80). If you change the currency to euros, we'll instead display it as €80.
