  • Username and email address.
  • The contents of forum posts, private messages, and chat messages

We use username and email address to provide you with an account (a contract with you) or when you subscribe to our newsletter (on the basis of your consent).

We use the content of forum posts, private messages and chat messages to provide you with the service (a contract with you) and to monitor content for compliance with our community rules (the legitimate interest of us and other players to have a safe environment to play our games in).

We use account information and payment information to provide you with the game, and the possibility to buy in-game currency (a contract with you).

We use login and navigational data to help with navigating around web pages or accessing secure areas of the website (a contract with you). Without these cookies, the website cannot function properly.

We have also engaged third-parties for analytics and advertising and social plug-ins. How they capture and use data is described under Cookies and other technologies.

Finally, as we develop our business, we might sell or buy businesses or assets. In the event of a corporate sale, merger, reorganization, bankruptcy, dissolution or similar event, your information may be part of the transferred assets.

How long and where do we store data?

If you made an account, we store data until you delete your account. We store other non-account related personal data that we collect for up to a year, and only aggregate data after that time. Aggregation data means that we can no longer look at data for individual players.

When a third-party service provider is a controller, they may keep data as well, either for a shorter or longer period.

We store newsletter subscriber information until such subscriber indicates they no longer want to receive the newsletter.

We store analytics and advertising data (insofar we have access) for up to 5 years to be able to analyze seasonal and mid-term trends.

How do we protect your information?

Taking into account the nature, scope, context and purpose of the processing, we have taken the following technical and organizational measures:

  • Access to our database and user accounts with third-party service providers is protected with access control.
  • Access to the database is limited, not all staff in our organization have full access.

We do not actively monitor the security of our database and need to rely on our processors to notify us of any data breaches.

Do we disclose any information to outside parties?

You should also know that your personal data may be transferred from your home country to third parties. If you are an EU resident, this could imply that we also transfer data to countries that do not offer an adequate level of protection for your personal data. When we transfer this data, we will do so only when we have put in place appropriate safeguards to protect your personal data. Please contact us to get a copy of the safeguards that we have put in place.
