We use this data to improve the performance of our platform and services, as well as to perform user experience and business analysis of our stores and applications.

We collect user journey information to deliver relevant sponsored content about our products. For example, we may use information about your purchases and interactions on the site to select content that matches your interests. We may share this information and customer identifiers, such as email address or device details, with third parties such as Facebook and Google. This will introduce you to relevant advertisements on third party sites and apps. We may also link this data to the different devices you use, as well as process data about ads (for example, whether you clicked on an ad and then made a purchase) which is used to measure ad performance.

We use this data to improve your platform experience, avoid errors and test new functionality. We also use it to analyse the user experience and business-relevant data.
