Information on tracking technology for Klarna.com/uk
Klarna.com Tracking Technology Notice
This document describes how we use tracking technologies such as cookies, pixels, web beacons, browser local storage and device fingerprinting (together “tracking technologies”) on the Klarna.com site, and your choices relating to these technologies.
What are tracking technologies?
The technologies we use are small pieces of information or code that a website transfers to or accesses from your computer or device to store, and sometimes track, information about you. An example of these are cookies that let websites remember information about you and your preferences, manage different features and content, store searches, and personalize content. Some cookies only last while you use our site. Some cookies are used to remember you when you visit again, and will last for longer.
What type of tracking technologies do we use?
The tracking technologies we use typically enhance our services towards you. Some of the functionalities we offer on our site actually need tracking technologies to work at all, other tracking technologies simply make our services smooother for you. We categorise the tracking technologies we use as follows:
Necessary tracking technologies
Some of these tracking technologies are necessary and can’t be switched off in our systems. These are technologies where the storage of (or access to) information is essential rather than reasonably necessary. For instance, we need to use these in order to provide a service to you or ensure our website functions, where it is in our legitimate interest to do so (balanced with your rights). Additionally, these tracking technologies can be strictly necessary in order to provide a service that you have signed up for, in which case we rely on the contract we have with you. We may also need to use them to comply with a legal obligation that we are subject to. You can set your browser to block or alert you about these tracking technologies, but it could result in parts of the site not working properly.
Example of data collected: Your preferences when it comes to the use of tracking technologies on Klarna.com to ensure that you are always presented with the correct Klarna experience, your tracking technology consent preferences and when you last changed them, or information about your participation in referral programs or eligibility for discounts or other benefits through Klarna.
All the necessary tracking technologies are set by Klarna and not by any third party except for AB Tasty which is set by a third party. AB Tasty’s privacy policy can be viewed
