1. WHAT ARE COOKIES?
Cookies are small data files placed on your computer or mobile device when you visit a website. Cookies are widely used by website operators in order to make their websites work, or to work more efficiently, as well as to provide reporting information.
Cookies set by the website operator (in this case, ProofRail) are called "first-party cookies." Cookies set by parties other than the website operator are called "third-party cookies." Third-party cookies enable third-party features or functionality to be provided on or through the website (such as authentication, security, and analytics). The parties that set these third-party cookies can recognize your device both when it visits the website in question and also when it visits certain other websites.
2. WHY DO WE USE COOKIES?
We use first- and third-party cookies for several reasons. Some cookies are required for technical reasons in order for our Website and Services to operate, and we refer to these as "essential" or "strictly necessary" cookies. Other cookies help us understand how visitors use our Website so we can improve it. Third parties serve cookies through our Website for authentication, security, and analytics purposes. This is described in more detail below.
We do not use advertising cookies, marketing cookies, or any cookies that build profiles of you for advertising purposes.
3. TYPES OF COOKIES WE USE
The specific types of first- and third-party cookies served through our Website and the purposes they perform are described below.
Strictly Necessary Cookies
These cookies are strictly necessary to provide you with services available through our Website and to use some of its features, such as access to secure areas and authenticated sessions. Because these cookies are strictly necessary to deliver the Website and Services, you cannot refuse them without impacting how our Website functions.

Analytics and Performance Cookies
These cookies collect information used in aggregate form to help us understand how our Website is being used or how effective our communications are, so we can improve them. We do not use this information for advertising or marketing, and we do not combine it with personally identifying data without your consent.

4. HOW CAN YOU CONTROL COOKIES?
You have the right to decide whether to accept or reject cookies.
Browser controls. Most web browsers allow some control of most cookies through the browser settings. To find out more about cookies, including how to see what cookies have been set, visit www.aboutcookies.org or www.allaboutcookies.org.
Guidance for managing cookies on common browsers can be found in their respective help centers:
- Google Chrome
- Mozilla Firefox
- Apple Safari
- Microsoft Edge
- Brave
Impact of refusing cookies. If you choose to reject the strictly necessary cookies described above, you will not be able to sign in to your account or use authenticated portions of the Services, as our authentication system relies on these cookies. Public pages of the Website will continue to function.
5. OTHER TRACKING TECHNOLOGIES
Cookies are not the only way to recognize or track visitors to a website. We may use other, similar technologies from time to time, such as web beacons (sometimes called "tracking pixels" or "clear gifs"). These are small graphics files that contain a unique identifier that enables us to understand when someone has visited our Website or opened an email we have sent. We use these technologies only in connection with the operation of the Services and our communications with you. We do not use them for advertising or marketing purposes.
In many instances, these technologies rely on cookies to function properly, and so declining cookies will impair their functioning.
We do not use Flash cookies, HTML5 local storage, or browser fingerprinting techniques for tracking purposes beyond what is required for authentication and security.
6. DO YOU SERVE TARGETED ADVERTISING?
No. We do not serve advertising and we do not use any cookies, web beacons, or similar tracking technologies for advertising or marketing purposes. We do not allow third parties to track you across our Website for advertising purposes. We do not sell or share your personal information for cross-context behavioral advertising as those terms are defined under applicable US state privacy laws.
7. UPDATES TO THIS COOKIE NOTICE
We may update this Cookie Notice from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please revisit this Cookie Notice regularly to stay informed about our use of cookies and related technologies.
The date at the top of this Cookie Notice indicates when it was last updated.
