Cookie Policy

Effective date:: April 2018
Last revised: April 2018

We use cookies and similar technologies for the purposes of the MediaView panel on our panel portal website (the “Portal”), during online surveys (the “Surveys”) and with our MediaView mobile application (the “App”) as set out by this Cookie Policy.

1 What are cookies, browser local storage and the mobile advertising ID (“cookies and similar technologies”)?

Cookies are small text files placed on your computer or mobile device when you access websites. “First party” cookies are set by websites that you are visiting at the time. “Third party” cookies are set by domains other than those of the websites that you visit.

Like cookies, the local storage technology allows websites to store information on a computer or mobile device. Local storage is typically persistent and, unlike cookies, data in local storage is not automatically transferred over the internet every time when the website is visited that stored the data.

The mobile advertising ID is a unique identifier (ID) set by the operating system of your mobile device. This ID is shared with apps that you install on your device and which may contain advertisements. Most devices allow apps to access the Mobile Advertiser ID by default. You may, however, be able to change your device settings to prevent your device from sharing this ID with apps. Check your operating systems' "Help" section to learn more about handling Mobile Advertising IDs. On Android, Advertising means the Android Advertising ID, on iOS devices it means the ID for Advertiser (IDFA).

We refer to cookies, local storage and the mobile advertising ID together as “cookies and similar technologies”.

2 How we use cookies and similar technologies

We use cookies and similar technologies:

  • on the Portal,
  • during Surveys

in order to

  • improve the respective websites’ performance and user experience,

3 Types of cookies that we use

Most cookies fall into one or more of the following categories:

3.1 Strictly necessary
These types of cookies are essential to provide services specifically requested by website visitors. Without them, websites cannot function or deliver the requested services. For the purposes of the Panel, we use strictly necessary cookies on the Portal and during online surveys.

3.2 Performance
These cookies collect information about how visitors use a website, such as which pages are most popular, which method of linking between pages is most effective, and if users encounter error messages from web pages. These cookies allow us to provide a high-quality user-experience. The information collected by these cookies does not identify users. They are designed to help improve how our website works.

3.3 Functionality
These cookies remember choices that you make so as to improve your experience.

We also provide social widgets on the Portal  – Facebook, Twitter, LinkedIn and other sharing tools – for users that would like to share content on our site with their friends, followers and connections. These social widgets are disabled by default, but you can enable them during your visit. If you enable the Like button, we will remember that preference on your next visit.

3.4 Targeting cookies
These cookies collect information about your browsing habits in order to make advertising relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of advertising campaigns. While targeting cookies are normally placed by advertising networks or by social networking firms with the website operator’s permission, we as market researchers set these cookies to measure ad exposure and deliver aggregated, statistical data to advertisers about the effectiveness of their campaigns. We use targeting cookies only with your consent as a participant in the Panel.

4 Can website users block cookies?

Yes, you can adjust the privacy settings in your browser to block all cookies; however, this could severely affect your browsing experience as many websites may not function properly. Your browser may allow you to delete all cookies upon closing your browser. This option, though, results in persistent cookies getting deleted that may store your preferences and personalized settings on websites that you visit regularly. It is possible to keep desired cookies, though, as your browser may allow you to specify which websites are always or never allowed to use cookies.
