What are 'cookies'?
Cookies are small text files which are downloaded to your computer or mobile device when you visit a website or application. Your web browser (such as Internet Explorer, Mozilla Firefox or Google Chrome) then sends these cookies back to the website or application on each subsequent visit so that they can recognise you and remember things like personalised details or user preferences.
Cookies are very useful and do lots of different jobs which help to make your experience on websites as smooth as possible. For example, they let you move between web pages efficiently, remembering your preferences, and generally improving your experience (see below for more examples). They can also help to ensure that adverts you see online are more relevant to you and your interests.
They are referred to as session or persistent cookies, depending on how long they are used:
- Session cookies only last for your online session and disappear from your computer or device when you close your browser.
- Persistent cookies stay on your computer or device after the browser has been closed and last for the period of time specified in the cookie. These persistent cookies are activated each time you visit the site where the cookie was generated.
Where we refer to “cookies” in this policy, we mean cookies or similar technologies.
Which cookies does CrescoData use and why?
When you use one of our Services either on a web browser or a device, the following 4 categories of cookies may be set:
- ‘Strictly necessary’ cookies
These cookies are essential in helping you to move around our website and app and to use their features, such as accessing secure areas of the website. Without these cookies, services you have asked for, such as setting up account log-in protection on CrescoData, cannot be provided. These cookies do not gather information about you that could be used for marketing or remembering where you’ve been on the internet.Some examples of these essential cookies include:
- Identifying you as being signed in to CrescoData services and keeping you logged in throughout your visit so that you don’t need to sign in each and every time you visit.
- Establishing links between your account and your device, for example if you link your CrescoData registered account to an Apple device, a file containing information establishing this link will be stored.
- Functional cookies
These cookies allow websites and applications to remember choices you make and provide enhanced, more personal features. They can also help us to display our advertisements and control how often an advertisement is shown to you, how long it is shown for and how often it will appear (these are commonly known as “ad-serving” or “ad delivery” cookies). Whilst these cookies don’t collect things like your name or email address, they do collect a unique user identifier code. This enables us to identify your device so that we can improve your experience and make sure your settings are remembered correctly.Some examples of how we do this include:
- Remembering if we’ve already asked you if you want to fill in a survey or if you’ve completed a survey, so you’re not asked to do it again.
- Remembering if you’ve been to the site before so that messages intended for first-time users are not displayed to you.
- Restricting the number of times you’re shown a particular advertisement. This is sometimes called ‘frequency capping’.
- Working out when to show you advertisements on any of the viewing services so that you don’t get shown too many.
- Making sure you get shown advertisements that are part of a sequence in the correct order.
- Analytics cookies
Again, these cookies do not identify you directly as they do not collect information such as your name or email address. However, the information collected by these cookies will be linked to a unique user identifier code. This is a random sequence of numbers and letters which we can use to link information collected by the cookies back to you without the cookies collecting your name or email address. This allows us to use the information collected by the cookies to understand more about your browsing habits and your interests so that we can make our advertising and marketing more relevant to you.
You can find out more about our advertising and marketing in our Security Policy.
How to control your cookies
There are various ways that you can control and manage your cookies which are discussed in a bit more detail below. Please remember that any settings you change will not just affect CrescoData cookies. These changes will apply to all websites that you visit (unless you choose to block cookies from particular sites). The settings you change will also only apply to the device on which you change them and will not apply across all your devices. If you want to opt out of cookies on all your devices, you will need to change the settings on all your devices individually.
Managing cookies in your browser
Most modern browsers will allow you to:
- See what cookies you’ve got and delete them on an individual basis
- Block third party cookies
- Block all cookies from being set
- Delete all cookies when you close your browser
You should be aware that any preferences will be lost if you delete all cookies. Ironically, this includes where you have opted out from cookies, as this requires an opt-out cookie to be set. This means that if you opt out from cookies and then delete all cookies, your opt out will not be saved and you will need to opt out again (which will store a strictly necessary cookie so that your device can remember that you have opted out).
If you block cookies completely, many websites will not work properly and some functionality on these websites will not work at all. We do not recommend turning cookies off when using our Services for these reasons.
The links below take you to the ‘Help’ sections for each of the major browsers so that you can find out more about how to manage your cookies.

Managing analytics cookies
It is possible to opt out of having your browsing activity recorded by analytics cookies. CrescoData uses the following analytics providers and you can opt out of their cookies by clicking on the following links. Please note that this will take you to the relevant third party’s website and generate a ‘no thanks’ cookie, which will stop any further cookies being set by those third parties.
Don’t forget that by not allowing analytics cookies, this stops us from being able to learn what people like or don’t like about CrescoData and our Services, so that we can make them better.
