International transfers

The personal information that we collect from you, as described in this Privacy Statement, could be transferred to or stored in countries which may not have the same data protection laws as the country in which you initially provided the information.

Cookie Statement

Whenever you use our website and Services, we use cookies and similar online tracking technologies (which we’ll also refer to as ‘cookies’ for the purpose of this Cookie Statement). Cookies can be used in various ways, including to make our website work, to analyse traffic, or for advertising purposes. Read on below to learn more about what a ‘cookie’ is, how they’re used and what your choices are.

For a detailed list of Greenstone’s cookies and categorizations please consult our cookie list.

What are cookies and online tracking technologies?

A web browser cookie is a small text file that websites place on your computer’s or mobile device’s web browser. These cookies store information about the content you view and interact with, in order to remember your preferences and settings or analyse how you use our website.

Cookies are divided into ‘first party’ and ‘third party’:

First party cookies are the cookies served by the owner of the domain – in our case that’s Greenstone. Any cookie we place ourselves is a ‘first party cookie’.

Third party cookies are cookies placed on our domains by trusted partners that we’ve chosen to allow to do so. These can be social media partners, advertising partners, security providers and more.

And they can be either ‘session cookies’ or ‘permanent cookies’:
Session cookies only exist until you close your browser, ending what is called your ‘session’. They are then deleted.

Permanent cookies have a range of different lifespans and stay on your device after the browser is closed. On our website, we try to only serve permanent cookies that have a limited lifespan. However, for security reasons, or in other exceptional circumstances, we might sometimes need to give a cookie a longer lifespan.

Web browser cookies may store information such as your IP address or another identifier, your browser type, and information about the content you view and interact with on our website. By storing this information, web browser cookies can remember your preferences and settings for online services and analyse how you use them.

Alongside cookies, we also use tracking technologies that are very similar. Our website, emails and mobile apps may contain small transparent image files or lines of code that record how you interact with them. These include ‘web beacons’, ‘scripts’ and ‘tracking URLs’:

Web beacons have a lot of different names. They might also be known as web bugs, tracking bugs, tags, web tags, page tags, tracking pixels, pixel tags, 1×1 GIFs or clear GIFs. In short, these beacons are a tiny graphic image of just one pixel that can be delivered to your device as part of a web page request or an advertisement. They can be used to retrieve information from your device, such as your device type or operating system, your IP address, and the time of your visit. They are also used to serve and read cookies in your browser or to trigger the placement of a cookie.

Scripts are small computer programs embedded within our web pages that give those pages a wide variety of extra functionality. Scripts make it possible for the website to function properly. For example, scripts power certain security features and enable basic interactive features on our website. Scripts can also be used for analytical or advertising purposes. For example, a script can collect information about how you use our website, such as which pages you visit or what you search for.

Tracking URLs are links with a unique identifier in them. These are used to track which website brought you to this website you’re using. An example would be if you click through from a social media page, search engine or one of our affiliate partners’ websites.

All these tracking technologies are referred to as ‘cookies’ here in this Cookie Statement.

How are cookies used?

They allow you to be recognised as the same user across the pages of a website, across devices, between websites or when you use our apps. When it comes to purpose, they are divided into three categories – functional cookies, analytical cookies and targeting cookies.

Functional cookies (also referred to as necessary cookies) are required to make our website function correctly and are used to create technologically advanced, user-friendly websites and apps that adapt automatically to your needs and preferences, so you can browse and book easily. This also includes enabling essential security and accessibility features. More specifically, these cookies:

Remember your selected currency and language settings, your past searches and other preferences to help you use our website and apps efficiently and effectively.
Analytical cookies (also referred to as performance cookies) measure and track how our website is used. We use this information to improve the website. More specifically, these cookies:

  • Help us understand how visitors use our website.
  • Help improve our website to make sure we’re interesting and relevant.
  • Allow us to find out what works and what doesn’t on our website.
  • Help us understand the effectiveness of advertisements and communications.
  • Teach us how users interact with our website after they have been shown an online advertisement, including advertisements on third-party websites.
  • Enable our business partners to learn whether or not their customers make use of any offers integrated into our or their websites.

The data we gather through these cookies can include which web pages you have viewed, which referring/exit pages you have entered and left from, which platform type you have used, which emails you have opened and acted upon, and date and time stamp information. It also means we can use details about how you’ve interacted with the site or app, such as the number of clicks you make on a given screen, your mouse movements and scrolling activity, the search words you use and the text you enter into various fields.

We also use targeting cookies to gather information about you over time, across multiple websites, applications, or other platforms. Targeting cookies help us to decide which products, services and interest-based advertisements to show you, both on and off our website and apps. More specifically, these cookies:

Categorize you into a certain interest profile, for instance, on the basis of the websites you visit and your click behavior.

Display personalized and interest-based advertisements both on our website and other websites. This is called ‘retargeting’ and is based on your browsing activities, such as the destinations you’ve been searching for, the accommodation you’ve viewed and the prices you’ve been shown. It can also be based on your shopping habits or other online activities. Retargeting ads can be shown to you both before and after you leave our website, as their purpose is to encourage you to browse or return to our website.

If you prefer, you can adapt your browser settings to choose to have your computer warn you each time a cookie is being sent, or to turn off all cookies. If you have activated a “Do Not Track” functionality on your device or browser, this will only affect cookies, not the remainder of Greenstone’s information collection and disclosure practices described in this Privacy Statement. 
To learn more about (or opt-out from) such advertising, you can visit the websites of the Digital Advertising Alliance at http://aboutads.info and Networking Advertising Initiative at http://networkadvertising.org/choices.
