What is a Cookie?

A cookie is a small amount of data, which often includes a unique identifier that is sent to your computer, tablet or mobile phone (all referred to here as a "device") web browser from a website's computer and is stored on your device's hard drive. Each website can send its own cookie to your web browser if your browser's preferences allow it. Many websites do this whenever a user visits their website in order to track online traffic flows. Similar technologies are also often used within emails to understand whether the email has been read or if any links have been clicked. If you continue without changing your settings, we’ll assume that you are happy to receive all cookies on the Stroma website.

However, you can change your cookie settings at any time.

During the course of any visit to a Stroma website, the pages you see, along with a cookie, are downloaded to your device. Many websites do this, because cookies enable website publishers to do useful things like find out whether the device (and probably its user) has visited the website before. This is done on a repeat visit by checking to see, and finding, the cookie left there on the last visit.
