The survey you complete is conducted by Trendstream Limited (GWI). This Survey Cookie Policy provides information about how and when we use cookies and similar technologies during the survey process.
For information about the cookies and similar technologies we use on our website (gwi.com) please see our GWI Website Cookie Policy..
What is a Cookie?
A cookie is a piece of data (text file) sent to your computer’s browser when you visit a website. Cookies and similar technologies are used for a range of purposes, including to remember your identity when completing a survey so you can pick up where you left off. We also use similar technologies referred to as ‘tags’ and ‘tracking pixels’ created for customers. These tags or tracking pixels are implemented on customer websites and may be used together with the cookie to track your internet activity, including what pages you visit on other sites, to determine the effectiveness of advertising on your behavior.
We might add, remove or update the cookies and similar technologies we use, and update this policy accordingly. We will let you know by updating the date at the top of this policy.
What is the difference between first and third party cookies?
First party cookies are set by the website you visit and only that website can access and read those cookies.
Third party cookies are set by someone other than the owner of the website you visit. These cookies can be used to track you on other websites that use the same third party service.
Cookies set in our survey may be set by us, third parties we are working with or customers.
What types of cookies does GWI use?
GWI uses both persistent and session cookies. This means:
Persistent: these cookies remain on your devices for a set period of time and the duration is set out in this GWI Survey Cookie Policy. Please note that these cookies will remain after you have closed your browser.
Session: these cookies are used to identify a visit to our survey and they will expire after a short period of time and deleted after you’ve closed your browser.
Our categories of cookies
Strictly necessary cookies.
These are cookies that are required for the operation of our survey. They include, for example, cookies that enable you to log into the survey. GWI uses an internal tool and a third party supplier (Qualtrics) to manage collection of your survey responses and both of these serve these cookies. As these are strictly necessary to deliver our survey, you cannot refuse them.
Functional cookies
These are used to recognise you when you return to our survey. This enables us to personalize our content for you and remember your preferences. For example, your language preference in the survey. These may be set by GWI or third party suppliers whose services are used to deliver the survey.
Analytics/performance cookies
They allow us to recognise and count traffic sources so GWI or a third party supplier used to deliver the survey can measure and improve the performance. For example, cookies that store your Identifier and session details to allow us to understand average completion times for surveys.
Advertising cookies
These cookies may be set by GWI or by our customers. They may be used by GWI to provide its GWIQ Services (described below). They may be used by customers to uniquely identify your browser and internet device in order to create tailored advertising experiences based on your interests.
When does GWI use cookies and similar technologies during a survey?
When you agree to take part in one of our surveys, you are asked to consent to the collection of cookies and similar technologies as part of the survey consent flow. GWI will only drop and use these non essential cookies and similar technologies if you have given your explicit consent.
How does GWI use cookies and similar technologies?
We use the data collected from cookies and similar technologies to:
What are the GWIQ Services?
For our GWIQ services, we drop a cookie and similar technologies on your device to identify the websites you use and your exposure to our customer’s online adverts and websites. This means that GWI is able through its GWIQ Services to provide customers with anonymous and aggregated insights about their advertising campaigns in relation to the real world.
The GWIQ Services include: i) reporting on whether a target audience (made up of you and others that are not identifiable to our customer) have seen our customer’s online advert (GWIQ Audience Validation) and ii) reporting on whether a target audience (made up of you and others that are not identifiable to our customer) have seen our customer’s website. We also use the cookie to see if you have seen an advert and then invite you back to complete an additional survey based on whether you did or didn’t see an advert or website (GWIQ Advertising Effectiveness).
For example, GWI may report to customers: X% of your target audience was exposed to your online advert in magazine website one vs Y% in magazine website two or 75% of your target audience watched 80% of your video advert before closing it.
To provide the GWIQ Services to customer, GWI collects the following Technical Data from you: two unique alphanumeric identifiers (one from the Panel Provider and one generated by GWI which are used to identify you as explained further in our GWI Survey Privacy Notice), your internet protocol (IP) address (used to generate location), location, user agent, language, host browser headers and attributes agreed with our customer. The attributes may include: total number of people exposed to an advert, frequency of the exposure, location on the website or advert, which advert was seen, how much of the advert you saw (for example x% of video was watched) and website domain. This information is used to provide the anonymous GWIQ Services described above.

Most browsers are configured to accept cookies by default, but you can update these settings to either refuse cookies altogether, or to notify you when a website is trying to set or update a cookie. Please be aware that the use of cookies and similar technologies is browser-specific. If you use multiple browsers or devices, you will need to modify your preferences on each one.
