Cookie Policy

Last updated on: 02/08/2019

At Catawiki, we use cookies and other tracking technologies on our website and app in various ways. That’s why we feel it’s important to explain to you what cookies are and why we use them. We’ve outlined all the details below, so we recommend reading our policy thoroughly to get a better understanding of how we use cookies and what your options are.

We value your privacy, so we always handle any personal data collected in accordance with the Catawiki Privacy Policy. You can find the definitions for capitalised terms in our Terms of Use.

What are cookies?

A cookie is a small piece of data placed in the browser of your computer or mobile device. Cookies use different methods to post data on or read data from users’ devices, such as your computer, laptop, tablet, or smartphone. They do this to help us recognise your device or store your preferences. The most well-known cookies are small (text) files that are placed on devices and can be identified again at a later stage. We also use other tracking techniques, such as javascript, web beacons (tags) (small blocks of code installed on a webpage, app, or ad that can retrieve certain information about the device and browser you use), or device fingerprinting, mobile identifiers, and tracking URLs. We refer to all these technologies as ‘cookies’ in this Cookie Policy.

How long do Catawiki’s cookies remain active?

The cookies we use vary in life span. A ‘session cookie’ will expire when you close your browser, while a ‘persistent cookie’ remains on your device for a longer period. See our cookie overview for the specific retention periods. The cookies we use vary in life span.

Which cookies do we use?

Our cookies fulfil different purposes, as specified below. To find out which cookies we use, have a look at our cookie overview.

Functional Cookies. Functional cookies are cookies that are necessary for the performance of our Online Marketplace. These cookies help us provide our services according to your preferences, helping you have a better Catawiki experience. There is, for instance, a cookie that makes sure you stay signed in. This means you don’t have to continuously sign in every time you go to a new page. These cookies also help us remember how you use certain features (e.g. lots you have marked as interesting) and account settings (e.g. language or display settings).

Analytics and research cookies. These cookies capture how you use Catawiki. We use the information from these cookies to analyse Online Marketplace usage and determine what causes errors. In general, analytics and research cookies are used to:

  • Track the number of users on the Online Marketplace
  • Track the time you spend on the Online Marketplace
  • Track the order in which you view different web pages
  • Decide which parts of the Online Marketplace need improvements
  • Show you feedback surveys
  • Understand what type of user you are

Marketing cookies. We use marketing cookies to understand what you like and how you behave on our Online Marketplace. We track your behaviour so we can get an idea about your preferences, store the IDs of the auctions you click on, and show you lots that match your interests. Third parties also place marketing cookies on Catawiki. This helps them show you tailored ads on third party websites, based on your behaviour on our Online Marketplace. In our cookie overview below, you’ll find the third parties that place marketing cookies when you visit Catawiki.

Furthermore, marketing cookies track which ads you’ve already seen, to make sure you aren’t seeing the same ads all the time. They also check whether you’ve clicked on an ad.

We only use marketing cookies with your consent. If you choose to turn off marketing cookies, you may still see online advertising, but the ads you see will not be tailored to your interests.

Your preferences are stored per Catawiki domain. Disabling marketing cookies on one domain (e.g. does not automatically mean they are disabled for our other domains as well.

The Catawiki app

You can also use our Online Marketplace through our app. The Catawiki app can be downloaded from the Apple App Store or the Google Play Store. We use methods similar to cookies and third-party services to ensure we understand how our users interact on our app and to make sure our app remains safe and secure. For instance, we use Fabric to track down bugs and errors. We also use the services of Selligent and Firebase to send you push notifications. These notifications serve many important functions (e.g. they can update you about an auction you’re interested in). You can change your push notification settings in our app.

Could this Cookie Policy be amended?
