This page is our Privacy Policy

A Privacy Policy tells you how we use your personal data, so you know what happens with it when you or other people give it to us. Personal data is any data that can identify you, either on its own or used with other data.

This Privacy Policy will help you understand your privacy rights, how and why we need to process your personal data, and how you can get in touch with us if needed.

Processing personal data involves any activity to do with that data, for example collection, storage, editing, and deletion.

This Privacy Policy also applies to children’s personal data that we may collect and use to assist with a service provided by us. For the purposes of this Privacy Policy we view a “child” to be any user who is under the age of 18.

We have presented this information in different sections so you can access the information you need more easily.

Personal data? What is that?

Anything that can identify you is your personal data. This can include your name, age, a photo of you, your email address, where you live, or your online gamertag.

There are some types of data we must be particularly careful with, known as ‘special category data.’ This could include data related to your health, or religious beliefs.

Sometimes we have to share personal data with the police to assist with their investigations.

Privacy and data protection laws

We are committed to complying with privacy and data protection laws in all countries in which we operate, to the extent that such laws are applicable to us.

We operate different websites, Apps (web and mobile) and an online retail shop (together referred to as the OS Sites and/or Services).

We must follow certain rules when we have your personal data.

We are committed to protecting your personal information and respecting your privacy. We may collect and process personal data about you in different ways, depending on the nature of our relationship with you.

We use cookies to distinguish you from other users of our Sites and Services.

The main reason we need to use your personal data is to know who you are. If we do not have your personal data, it could mean you miss out on the things we can do for you.

We use online marketing to keep you up to date with our products and offers.

Your personal information may be transferred to, and processed in, countries other than the country in which you are a resident. These countries may have data protection laws that are different to the laws of your country (and, in some cases, may not be as protective).

We store personal data as either secure physical records, or electronically on our internal IT systems, in cloud storage, and in some cases, records on third party servers, which may be located in various countries (please see the "Data transfers to third countries" section above for more details).

We will retain your personal data for as long as necessary to fulfil the purposes we collected it for, including the purposes of satisfying any legal, accounting, or reporting requirements. We may also retain your personal data for a reasonable period after collecting it, to allow us to respond to any follow up enquiries or complaints, or for as long as you remain a registered user of our products and services.
